| Corporate information and statement of IFRS compliance [abstract] | |
| Selected accounting policies | Selected accounting policies Basis of preparation These Condensed Consolidated Interim Financial Statements for Alcon Inc. ("the Company") and the subsidiaries it controls (collectively, "Alcon") have been prepared in accordance with International Accounting Standard 34, Interim Financial Reporting, as issued by the International Accounting Standards Board ("IASB") and with the accounting policies as described in Note 2 to the December 31, 2024 Consolidated Financial Statements in the Company’s 2024 Form 20-F ("Form 20-F"). These Condensed Consolidated Interim Financial Statements do not include all of the information required for a complete set of International Financial Reporting Standards ("IFRS") financial statements. The financial information consolidates the Company and the subsidiaries it controls, and includes selected notes to explain events and transactions that are significant to an understanding of the changes in Alcon's financial position and performance since the prior annual Consolidated Financial Statements. For non-wholly owned subsidiaries, non-controlling interests are recognized to reflect the portion of equity that is not attributable, directly or indirectly, to Alcon. The Condensed Consolidated Interim Financial Statements should be read in conjunction with the annual Consolidated Financial Statements for the year ended December 31, 2024, which have been prepared in accordance with IFRS as issued by the IASB ("IFRS Accounting Standards") and can be found in the Form 20-F. The accompanying Condensed Consolidated Interim Financial Statements present our historical financial position, results of operations, comprehensive income and cash flows in accordance with IFRS Accounting Standards. Alcon's principal accounting policies are set out in Note 2 to the Consolidated Financial Statements in the Form 20-F. Use of estimates and assumptions The preparation of Condensed Consolidated Interim Financial Statements requires management to make certain estimates and assumptions, either at the balance sheet date or during the period, that affect the reported amounts of assets and liabilities as well as revenues and expenses. Because of the inherent uncertainties, actual outcomes and results may differ from management's assumptions and estimates. Business combinations The business combinations accounting policy was expanded in 2025 to include business combinations achieved in stages and non-controlling interests, as follows: If the business combination is achieved in stages, the acquisition date carrying value of Alcon’s previously held equity interest in the acquiree is remeasured to fair value at the acquisition date. Any gains or losses arising from such remeasurement are recognized in Other income or Other expense, respectively, in the Consolidated Income Statement. Alcon recognizes non-controlling interests in the acquired entity on an acquisition-by-acquisition basis, either at fair value or at the non-controlling interests' proportionate share of the acquired entity’s net identifiable assets. This decision is made on an acquisition-by-acquisition basis. Treasury shares The accounting policies were expanded in 2025 to include treasury shares acquired in repurchases, as follows: Common shares repurchased, which are measured at fair value on their trade date and include transaction costs directly attributable to the repurchase, are held in treasury and deducted from equity. No gains or losses are recognized in the Consolidated Income Statement on the purchase or issuance of such shares. Payments for the acquisition of treasury shares are recorded in Financing activities in the Consolidated Statement of Cash Flows. Treasury share repurchases denominated in a currency other than the reporting currency are valued at the trade date using the spot exchange rate for the reporting currency. Any realized foreign exchange gains or losses arising between the trade date and settlement date is recognized in Other financial income & expense in the Consolidated Income Statement. If the trade date by the broker or bank and settlement date of the repurchase by the Company fall in different reporting periods, an accrued liability is recognized at period-end for the settlement obligation in Provisions & other current liabilities on the Consolidated Balance Sheet. Impairment of goodwill, Alcon brand name and definite lived intangible assets As discussed in Note 2 to the Consolidated Financial Statements in the Form 20-F, Goodwill, the Alcon brand name and acquired in-process research & development ("IPR&D") projects are reviewed for impairment at least annually and these, as well as all other investments in intangible assets, are reviewed for impairment whenever events or changes in circumstance indicate that the asset's balance sheet or reportable segment carrying amount may not be recoverable. Goodwill and other intangible assets represent a significant amount of total assets on the Consolidated Balance Sheet. Impairment testing may lead to potentially significant impairment charges in the future, which could have a materially adverse impact on Alcon's results of operations and financial condition. New standards and interpretations not yet adopted In April 2024, the IASB issued IFRS 18, Presentation and Disclosure in Financial Statements, which will replace IAS 1, Presentation of Financial Statements and accompanies limited amendments to other standards which will be effective upon the adoption of the new standard. IFRS 18 will be retroactively effective for our annual reporting periods beginning on January 1, 2027, with early adoption permitted. The standard is expected to improve comparability and transparency of financial statements by requiring defined subtotals in the Consolidated Income Statement, requiring disclosure of management-defined performance measures and adding new principles for aggregation and disaggregation of information. Alcon is currently evaluating the impact of this standard on its Consolidated Financial Statements. Other than previously described, as of June 30, 2025 there are no IFRS Accounting Standards, interpretations or amendments not yet effective that would be expected to have a material impact on Alcon upon adoption.

| Significant Transactions [Abstract] | |
| Significant transactions | Significant transactions Significant transactions in 2025 Vision Care - Acquisition of majority interest in Aurion Biotech, Inc. On March 24, 2025, Alcon closed on agreements with certain existing shareholders of Aurion Biotech, Inc. ("Aurion") to acquire approximately 58.7% of outstanding equity for approximately $486 million and outstanding convertible notes from the same shareholders for approximately $36 million, totaling $522 million cash paid at closing. When combined with Alcon's existing 40.3% investment in Aurion, the transaction resulted in 99% ownership of Aurion on an outstanding basis. Aurion's ownership on a fully diluted basis at closing was approximately 85.0% held by Alcon and 15.0% held by non-controlling interests. This transaction supports Alcon's ophthalmic pharmaceutical portfolio expansion, including biopharmaceutical applications, with the potential to advance the first-ever corneal cell therapy candidate. The acquisition of majority interest was accounted for as a business combination that resulted in goodwill of $140 million after the preliminary purchase price allocation ("PPA") of the consideration to the fair values of acquired assets and assumed liabilities. The fair values of the acquired assets and assumed liabilities are provisional primarily due to pending final measurement of the non-controlling interests and valuation of acquired tax attributes. Total cash paid at closing, net of cash acquired, was $496 million. Refer to Note 11 for additional information, including preliminary PPA and details related to the associated non-controlling interests. Surgical - Acquisition of Cylite Pty Ltd. On January 16, 2025, Alcon executed a stock purchase agreement and acquired approximately 91.2% of outstanding equity from Cylite Pty Ltd. ("Cylite") shareholders, resulting in 100% ownership when combined with Alcon's existing 8.8% investment in Cylite. The Cylite diagnostic device complements Alcon’s existing Surgical portfolio for cataracts. The acquisition of the remaining equity interest was accounted for as a business combination that resulted in goodwill of $90 million after the preliminary PPA of the consideration to the fair values of acquired assets and assumed liabilities. The fair value of the assets acquired and liabilities assumed for the acquisition were based on preliminary calculations and valuations, and the estimates and assumptions for this acquisition are subject to change as additional information is obtained during the respective measurement period up to one year from the acquisition date. Total cash paid at closing, net of cash acquired, was $72 million. Refer to Note 11 for additional information and preliminary PPA. Significant transactions in 2024 Divestment of product rights and out-licensing in China On October 17, 2024, Alcon closed on a set of definitive agreements to divest its rights in China in favor of Ocumension Therapeutics (Hong Kong) Limited (“Ocumension”) to Bion Tears and Tears Naturale (reported in Vision Care segment) and procedural eye drops (reported in Surgical segment). Under the terms of the agreements, Ocumension licensed the exclusive commercialization rights to Systane Ultra in China and development and commercialization rights to AR-15512 in China. In exchange, Alcon received up-front consideration of $116 million in the form of approximately 16.7% of the ordinary shares of Ocumension. Alcon will also receive royalties and defined AR-15512 sales milestones. Surgical - Acquisition of BELKIN Vision Ltd. On July 1, 2024, Alcon acquired 100% of the outstanding shares and equity of BELKIN Vision Ltd. ("BELKIN") as provided under the Agreement and Plan of Merger. This transaction complements Alcon’s existing Surgical portfolio in the treatment of glaucoma. The acquisition was accounted for as a business combination that resulted in goodwill of $20 million after the PPA of the consideration to the fair values of acquired assets and assumed liabilities. Total cash paid at closing for the net identifiable assets recognized, net of cash acquired, was $61 million.

| Segmentation of key figures | Segmentation of key figures The segment information disclosed in these Condensed Consolidated Interim Financial Statements reflects historical results consistent with the identifiable reportable segments of Alcon and financial information that the Chief Operating Decision Maker ("CODM") reviews to evaluate segmental performance and allocate resources among the segments. The CODM is the Executive Committee of Alcon. The businesses of Alcon are divided operationally on a worldwide basis into two identified reportable segments, Surgical and Vision Care. Alcon's reportable segments are the same as its operating segments as Alcon does not aggregate any operating segments in arriving at its reportable segments. As indicated below, certain income and expenses are not allocated to segments. Reportable segments are presented in a manner consistent with the internal reporting to the CODM. The reportable segments are managed separately due to their distinct needs and activities for research, development, manufacturing, distribution and commercial execution. The Executive Committee of Alcon is responsible for allocating resources and assessing the performance of the reportable segments. In Surgical, Alcon researches, develops, manufactures, distributes and sells ophthalmic products for cataract surgery, vitreoretinal surgery, refractive laser surgery and glaucoma surgery. The surgical portfolio also includes implantables, consumables and surgical equipment required for these procedures and supports the end-to-end procedure needs of the ophthalmic surgeon. In Vision Care, Alcon researches, develops, manufactures, distributes and sells daily disposable, reusable, and color-enhancing contact lenses, cell therapies to treat ocular diseases and a comprehensive portfolio of ocular health products, including products for dry eye, ocular allergies, glaucoma and contact lens care, as well as ocular vitamins and redness relievers. Alcon also provides services, training, education and technical support for both the Surgical and Vision Care businesses. The basis of preparation and the selected accounting policies mentioned in Note 1 are used in the reporting of segment results. The Executive Committee of Alcon evaluates segmental performance and allocates resources among the segments based on net sales and segment contribution, which is the single measure of segment profitability. Net identifiable assets are not assigned to the segments in the internal reporting to the CODM, and are not considered in evaluating the performance of the business segments by the Executive Committee of Alcon. Segment contribution excludes amortization and impairment charges for acquired product rights or other intangibles, general and administrative expenses for corporate activities, fair value adjustments to contingent consideration liabilities, past service costs primarily for post-employment benefit plan amendments, acquisition and integration related costs, certain acquisition and divestment related items, product discontinuation costs, fair value adjustments of financial assets in the form of options to acquire a company carried at fair value through profit and loss ("FVPL"), net gains and losses on fund investments and equity securities valued at FVPL, fair value remeasurements of investments in associated companies, restructuring costs, legal provisions and settlements and other income and expense items not attributed to a specific segment.

| Earnings per share [abstract] | |
| Dividends, earnings per share and share repurchase program | Dividends, earnings per share and share repurchase program Dividends On February 25, 2025, the Company's Board of Directors (the "Board") proposed a dividend of CHF 0.28 per share, which was subsequently approved by the shareholders at the Annual General Meeting on May 6, 2025 and paid in May 2025 for an amount of $166 million. On February 27, 2024, the Board proposed a dividend of CHF 0.24 per share, which was subsequently approved by the shareholders at the Annual General Meeting on May 8, 2024 and paid in May 2024 for an amount of $130 million. Earnings per share As of June 30, 2025, there were 494.4 million outstanding common shares after repurchases of 1.4 million common shares, partially offset by the delivery of 1.1 million net shares vesting under the equity incentive programs during the six months ended June 30, 2025. Basic earnings per share is computed by dividing net income attributable to shareholders of Alcon Inc. for the period by the weighted average number of common shares outstanding during the period. For the three and six months ended June 30, 2025, the weighted average number of shares outstanding was 495.2 million. For the three and six months ended June 30, 2024, the weighted average number of shares outstanding was 494.5 million and 494.1 million, respectively. The only potentially dilutive securities are the outstanding unvested equity-based awards, as described in Note 9. Except when the effect would be anti-dilutive, the calculation of diluted earnings per common share includes the weighted average net impact of unvested equity-based awards. For the three and six months ended June 30, 2025, the weighted average diluted number of shares outstanding was 497.9 million, which includes the potential conversion of 2.7 million unvested equity-based awards. For the three and six months ended June 30, 2024, the weighted average diluted number of shares outstanding was 497.0 million and 496.7 million, respectively, which includes the potential conversion of 2.5 million and 2.6 million unvested equity-based awards, respectively. Share repurchase program On February 25, 2025, the Board authorized the repurchase of up to $750 million of the Company’s common shares. The shares acquired are held in treasury and are intended to offset the dilutive effect of shares vesting under Alcon's equity-based incentive plans. Alcon expects to fund the repurchases through cash generated from operations. The program is authorized by the Swiss Takeover Board and subject to customary safe harbor conditions. The timing and total amount of share repurchases will depend upon a variety of factors. The share repurchase program is expected to be completed over a three year period but may be suspended or discontinued at any time. On March 27, 2025, the Company executed an agreement with a bank to set the terms on which the bank will execute the share repurchases as the Company's agent. The agreement with the bank is cancellable at any time without continuing obligation such that no financial liability exists to the Company from execution of the agreement or the approval of the program. As of June 30, 2025, 1.4 million shares were repurchased for a total consideration of $121 million. Total cash payments for acquisition of treasury shares of $116 million were recorded to "Payments for acquisition of treasury shares" within the financing section of the Consolidated Statement of Cash Flows. Liabilities of $5 million were recorded to "Provisions & other current liabilities" on the Condensed Consolidated Balance Sheet for share repurchases which were initiated but not settled as of June 30, 2025.

| Financial instruments | Financial instruments Fair value by hierarchy As required by IFRS, financial assets and liabilities recorded at fair value in the Condensed Consolidated Interim Financial Statements are categorized based upon the level of judgment associated with the inputs used to measure their fair value. There are three hierarchical levels, based on an increasing amount of judgment associated with the inputs to derive fair value for these financial assets and liabilities, which are as follows: Financial assets and liabilities carried at Level 1 fair value hierarchy are listed in active markets. Financial assets and liabilities carried at Level 2 fair value hierarchy are valued using corroborated market data. Level 1 financial assets include money market funds, equity securities in public companies and deferred compensation assets. There were no financial liabilities carried at Level 1 fair value, and Level 2 financial assets and liabilities include derivative financial instruments. Investments in money market funds and equity securities in public companies are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices. Investments in money market funds are classified as Cash & cash equivalents within the Condensed Consolidated Balance Sheet. Deferred compensation investments for certain employee benefit plans are held in a rabbi trust and dedicated to pay the benefits under the associated plans but are not considered plan assets as the assets remain available to creditors of Alcon in certain events, including bankruptcy. Rabbi trust assets primarily consist of investments in mutual funds. These assets are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices. Level 3 inputs are unobservable for the financial asset or liability. Fair value measurements classified as Level 3 are performed primarily using the income approach or market approach. The financial assets and liabilities generally included in the Level 3 fair value hierarchy are equity securities and convertible notes receivable of private companies measured at fair value through other comprehensive income ("FVOCI"), fund investments, options to acquire private companies, and contingent consideration liabilities measured at FVPL. The below table summarizes financial assets and liabilities measured at fair value on a recurring basis as of June 30, 2025 and December 31, 2024.
(1) As of December 31, 2024, included $11 million of Long-term convertible notes due from associated companies. (2) Recorded in Other non-current assets. (3) Recorded in Other current assets. There were no transfers of financial assets or liabilities between levels in the fair value hierarchy during the six months ended June 30, 2025. The carrying amount is a reasonable approximation of fair value for all other financial instruments as of June 30, 2025 and December 31, 2024, with the exception of the Series 2026, 2028, 2029, 2030, 2032, 2049 and 2052 Notes ("Notes") recorded in Non-current financial debt. As of June 30, 2025, the Notes had a fair value of $4,392 million and a carrying value of $4,607 million. As of December 31, 2024, the Notes had a fair value of $4,240 million and a carrying value of $4,538 million. The fair value of the Notes was determined using Level 2 inputs. The Notes were valued using the quoted market price for such Notes, which have low trading volumes. Level 3 financial instruments measured at fair value on a recurring basis Financial assets
Financial liabilities
Additions to contingent consideration liabilities in the current year period relate to the Cylite acquisition. Refer to Note 11 for additional information. As of June 30, 2025, the probability of success for various development and commercial milestones ranges from 0% to 95% and the maximum remaining potential payments related to contingent consideration from business combinations is $790 million, plus other amounts calculated as a percentage of commercial sales in cases where there is not a specified maximum contractual payment amount. The estimation of probability typically depends on factors such as technical milestones or market performance and is adjusted for the probability of payment. If material, probable payments are appropriately discounted to reflect the impact of time. Contingent consideration liabilities are reported in “Provisions & other non-current liabilities" based on the projected timing of settlement which is estimated to range from late 2026 through 2036 for contingent consideration obligations as of June 30, 2025. Long-term note receivable and other financial assets measured at amortized cost As described in Note 17 to the Consolidated Financial Statements in the Form 20-F, on May 22, 2023, Alcon entered into financing arrangements with a long-term supplier, Lifecore Biomedical, Inc. and certain of its affiliates (collectively, “Lifecore”) resulting in financial assets which Alcon concluded were originated credit-impaired. The maximum exposure to credit risk is reflected in the carrying value of the assets, which amounted to $184 million as of June 30, 2025, including a non-current portion of $183 million in Financial assets and a current portion of $1 million in Other current assets. As of June 30, 2025, in accordance with the terms of the Pledge and Security agreement (“security agreement”), the credit risk exposure is fully mitigated by the collateral, with an estimated amount of approximately $385 million. The estimated amount of collateral increased approximately 20% from December 31, 2024 based on updated forecasts reflecting recent market data and discounted cash flow analysis. There have been no significant changes in the quality of the collateral, the terms of the signed security agreement or the credit monitoring procedures described in Note 17 to the Consolidated Financial Statements in the Form 20-F. In addition, as of June 30, 2025, Alcon assessed there was no lifetime expected credit loss due to the value of the collateral under the security agreement. Derivatives The below table summarizes the net value of unsettled positions for currency derivatives contracts including swaps, forwards and options as of June 30, 2025 and December 31, 2024.
There are master agreements with several banking counterparties for derivative financial instruments; however, there were no derivative financial instruments meeting the offsetting criteria under IFRS as of June 30, 2025 or December 31, 2024. Nature and extent of risks arising from financial instruments Note 17 to the Consolidated Financial Statements in the Form 20-F contains a summary of the nature and extent of risks arising from financial instruments. There have been no significant updates to our assessment of the nature and extent of risks arising from financial instruments or corresponding risk management policies during the period.

| Other Provisions, Contingent Liabilities And Contingent Assets [Abstract] | |
| Legal proceedings update | Legal proceedings update A number of Alcon companies are, and will likely continue to be, subject to various legal proceedings and investigations that arise from time to time, including proceedings regarding product liability, sales and marketing practices, commercial disputes, mergers and acquisitions, employment, wrongful discharge, antitrust, securities, health and safety, environmental, tax, international trade, privacy, intellectual property, including under the Hatch-Waxman Act, and anti-bribery matters such as those under the Foreign Corrupt Practices Act of 1977, as amended. As a result, Alcon may become subject to substantial liabilities that may not be covered by insurance and could affect Alcon's business, financial position and reputation. While Alcon does not believe that any of these legal proceedings will have a material adverse effect on its financial position, litigation is inherently unpredictable and large judgments sometimes occur. As a consequence, Alcon may in the future incur judgments or enter into settlements of claims that could have a material adverse effect on its results of operations or cash flow. Note 18 to the Consolidated Financial Statements in the Form 20-F contains a summary of significant legal proceedings to which Alcon or any of its subsidiaries was a party as of the date of the Form 20-F. In the first quarter of 2025, both Alcon and the generic drug company defendant in the patent litigation concerning Simbrinza filed notices of appeal of certain rulings made by the trial court. As of August 19, 2025, there have been no other significant developments in the proceedings described in the Form 20-F nor any new significant proceedings commenced since the date of the Form 20-F. Alcon believes that its total provisions for litigation and other legal matters are adequate based upon currently available information. However, given the inherent difficulties in estimating liabilities, additional liabilities and costs may be incurred beyond the amounts provided.

| Acquisitions | Acquisitions Acquisitions of businesses During the first six months of 2025, acquisitions of businesses included Aurion Biotech, Inc. and Cylite Pty Ltd., described below. There were no acquisitions of businesses during the first six months of 2024. Vision Care - Acquisition of majority interest in Aurion Biotech, Inc. On March 24, 2025, Alcon closed on agreements with certain existing shareholders of Aurion to acquire approximately 58.7% of outstanding equity for approximately $486 million and outstanding convertible notes from the same shareholders for approximately $36 million, totaling $522 million cash paid at closing. When combined with Alcon's existing 40.3% investment in Aurion, the transaction resulted in 99% ownership of Aurion on an outstanding basis. Aurion's ownership on a fully diluted basis at closing was approximately 85.0% held by Alcon and 15.0% held by non-controlling interests. This transaction supports Alcon's ophthalmic pharmaceutical portfolio expansion, including biopharmaceutical applications, with the potential to advance the first-ever corneal cell therapy candidate. The acquisition of majority interest was accounted for as a business combination that resulted in goodwill of $140 million after the preliminary PPA of the consideration to the fair values of acquired assets and assumed liabilities. Total cash paid at closing, net of cash acquired, was $496 million. The transaction also resulted in non-controlling interests, described below. The acquisition date fair value of the equity interest previously held by Alcon was $334 million, resulting in a remeasurement fair value gain of $136 million in the first quarter of 2025. The fair value gain has been included in Other income in the Condensed Consolidated Income Statement. The preliminary PPA for the Aurion acquisition was not finalized as of the date the first quarter of 2025 interim financial statements were issued. During the second quarter of 2025, Alcon recorded a measurement period adjustment to fair values of acquired intangible assets, which resulted in an increase of $5 million to Currently marketed products and a decrease of $5 million to the Acquired IPR&D. The below table summarizes the updated preliminary PPA for the Aurion business combination. The PPA remains provisional pending final measurement of the non-controlling interests and valuation of acquired tax attributes.
Goodwill is attributable primarily to assembled workforce and biopharmaceutical research and development capabilities. The goodwill is not deductible for tax purposes. Direct acquisition costs of $2 million were recognized in Other expense in the Condensed Consolidated Income Statement and were reported in operating cash flows in the Condensed Consolidated Statement of Cash Flows. Subsequent to the acquisition, the current and non-current financial debts were repaid in the second quarter of 2025. Pro forma financial information is not presented for the Aurion business acquisition as it is not material to the Condensed Consolidated Financial Statements. For the period from the date of the Aurion acquisition, March 24, 2025, through June 30, 2025, the acquired business reduced Alcon's Net income by $17 million. Non-controlling interests Alcon elected to recognize the non-controlling interests in Aurion at fair value. Non-controlling interests with a fair value of $27 million were recognized at acquisition date, comprised of common stock and vested options. The fair value of non-controlling interests was estimated using the market and income approaches, which were equally weighted. The income approach valuation utilized net present value techniques which involve significant judgement by management and include assumptions with measurement uncertainty. The estimates include cash flow projections for a five-year period based on management forecasts, sales forecasts beyond the five-year period extrapolated using long-term expected growth rates, discount rates and future tax rates. Actual cash flows and values could vary significantly from forecasted future cash flows and related values derived using net present value techniques. Since the cash flow projections are a significant unobservable input, the fair value of the non-controlling interests was classified as Level 3 in the fair value hierarchy. On March 26, 2025, the Aurion Board exercised their discretion under the Aurion stock plan and approved an exchange of outstanding vested options of Aurion employees for cash as settlement of their non-controlling interests in Aurion. As a result, Alcon's fully diluted interest in Aurion increased from 85.0% on the business combination date to 91.2% as of June 30, 2025. The below table summarizes movements in the non-controlling interests on a fully diluted basis from the acquisition date to the end of the reporting period.
Profits and losses attributable to non-controlling interests are calculated on an outstanding basis. Surgical - Acquisition of Cylite Pty Ltd. On January 16, 2025, Alcon executed a stock purchase agreement and acquired approximately 91.2% of outstanding equity from Cylite shareholders, resulting in 100% ownership when combined with Alcon's existing 8.8% investment in Cylite. The Cylite diagnostic device complements Alcon’s existing Surgical portfolio for cataracts. The acquisition of the remaining equity interest was accounted for as a business combination that resulted in goodwill of $90 million after the preliminary PPA of the consideration to the fair values of acquired assets and assumed liabilities. Total cash paid at closing, net of cash acquired, was $72 million. The development milestone contingent consideration is related to a potential payment of up to $10 million upon achievement of the first commercial sale of a defined product within the United States. The contingent consideration recognized during the first quarter of 2025 represents its fair value (Level 3) at the acquisition date. The acquisition date fair value of the equity interest previously held by Alcon was $14 million, resulting in a remeasurement fair value gain of $6 million in the first quarter of 2025. The fair value gain has been included in Other income in the Condensed Consolidated Income Statement. The below table summarizes the preliminary PPA for the Cylite business combination at acquisition date. The fair value of the assets acquired and liabilities assumed for the acquisition were based on preliminary calculations and valuations, and the estimates and assumptions for this acquisition are subject to change as additional information is obtained during the respective measurement period up to one year from the acquisition date.
Goodwill is attributable primarily to buyer-specific synergies, including benefits to intraocular lens sales, development collaboration arrangement and associated development timeline reduction, and assembled workforce. The goodwill is not deductible for tax purposes. Direct acquisition costs of $1 million were recognized in Other expense in the Condensed Consolidated Income Statement and were reported in operating cash flows in the Condensed Consolidated Statement of Cash Flows. Pro forma financial information is not presented for the Cylite business acquisition as it is not material to the Condensed Consolidated Financial Statements. For the period from the date of the Cylite acquisition, January 16, 2025, through June 30, 2025, the acquired business reduced Alcon's Net income by $8 million. Proposed acquisition of LENSAR, Inc. On March 23, 2025, Alcon entered into a definitive agreement to acquire all outstanding shares of LENSAR, Inc. ("LENSAR"), a global medical technology company focused on advanced laser solutions for the treatment of cataracts, with a total consideration of up to approximately $430 million. The planned acquisition will complement Alcon’s existing Surgical portfolio in the treatment of cataracts. The transaction is subject to customary closing conditions, including regulatory approval and approval by LENSAR’s stockholders, and is expected to close in late 2025.

| Subsequent events | Subsequent events On July 7, 2025, Alcon entered into a definitive agreement to acquire 100% of the outstanding equity of LumiThera, Inc. (“LumiThera”), a privately held, US-based company and manufacturer of the Valeda photobiomodulation device, a multi-wavelength treatment for dry age-related macular degeneration. The planned acquisition will expand Alcon's Surgical portfolio. Pursuant to the terms of the agreement, Alcon agreed to pay $132 million, which represents up-front consideration of $140 million less the value of Alcon's equity interest and certain deductions, and additional amounts to be potentially paid upon achievement of certain regulatory and commercial milestones. The transaction is subject to customary closing conditions and is expected to close in the third quarter of 2025. On August 4, 2025, Alcon entered into a definitive agreement to acquire STAAR Surgical Company ("STAAR"), a global medical technology company focused on the research, development, manufacturing, distribution and sale of phakic intraocular lenses. The planned acquisition will complement Alcon’s existing Surgical portfolio in the treatment of myopia. Pursuant to the terms of the agreement, Alcon agreed to pay $28.00 per share to acquire all outstanding shares of STAAR’s common stock for total consideration of approximately $1.5 billion. The transaction is subject to customary closing conditions, including regulatory approval and approval by STAAR’s shareholders, and is expected to close in six to 12 months. On July 4, 2025, the United States Congress enacted budget reconciliation bill H.R. 1, which includes significant provisions such as the permanent extension of certain provisions of the Tax Cuts and Jobs Act that were set to expire. The legislation has multiple effective dates, with certain provisions effective in 2025 and others to be implemented through 2027. The enactment of H.R. 1 did not impact Alcon's Condensed Consolidated Financial Statements for the period ended June 30, 2025. Alcon is continuing to evaluate the potential future impact of these tax law changes on our consolidated results of operations, financial position and cash flows. These unaudited Condensed Consolidated Interim Financial Statements were authorized for issue by the Audit & Risk Committee on August 19, 2025.

| Corporate information and statement of IFRS compliance [abstract] | |
| Statement of IFRS compliance | The accompanying Condensed Consolidated Interim Financial Statements present our historical financial position, results of operations, comprehensive income and cash flows in accordance with IFRS Accounting Standards. |
| Use of estimates and assumptions | Use of estimates and assumptions The preparation of Condensed Consolidated Interim Financial Statements requires management to make certain estimates and assumptions, either at the balance sheet date or during the period, that affect the reported amounts of assets and liabilities as well as revenues and expenses. Because of the inherent uncertainties, actual outcomes and results may differ from management's assumptions and estimates.
|
| Business combinations | Business combinations The business combinations accounting policy was expanded in 2025 to include business combinations achieved in stages and non-controlling interests, as follows: If the business combination is achieved in stages, the acquisition date carrying value of Alcon’s previously held equity interest in the acquiree is remeasured to fair value at the acquisition date. Any gains or losses arising from such remeasurement are recognized in Other income or Other expense, respectively, in the Consolidated Income Statement. Alcon recognizes non-controlling interests in the acquired entity on an acquisition-by-acquisition basis, either at fair value or at the non-controlling interests' proportionate share of the acquired entity’s net identifiable assets. This decision is made on an acquisition-by-acquisition basis.
|
| Treasury shares | Treasury shares The accounting policies were expanded in 2025 to include treasury shares acquired in repurchases, as follows: Common shares repurchased, which are measured at fair value on their trade date and include transaction costs directly attributable to the repurchase, are held in treasury and deducted from equity. No gains or losses are recognized in the Consolidated Income Statement on the purchase or issuance of such shares. Payments for the acquisition of treasury shares are recorded in Financing activities in the Consolidated Statement of Cash Flows. Treasury share repurchases denominated in a currency other than the reporting currency are valued at the trade date using the spot exchange rate for the reporting currency. Any realized foreign exchange gains or losses arising between the trade date and settlement date is recognized in Other financial income & expense in the Consolidated Income Statement. If the trade date by the broker or bank and settlement date of the repurchase by the Company fall in different reporting periods, an accrued liability is recognized at period-end for the settlement obligation in Provisions & other current liabilities on the Consolidated Balance Sheet.

| Impairment of goodwill, Alcon brand name and definite lived intangible assets | Impairment of goodwill, Alcon brand name and definite lived intangible assets As discussed in Note 2 to the Consolidated Financial Statements in the Form 20-F, Goodwill, the Alcon brand name and acquired in-process research & development ("IPR&D") projects are reviewed for impairment at least annually and these, as well as all other investments in intangible assets, are reviewed for impairment whenever events or changes in circumstance indicate that the asset's balance sheet or reportable segment carrying amount may not be recoverable. Goodwill and other intangible assets represent a significant amount of total assets on the Consolidated Balance Sheet. Impairment testing may lead to potentially significant impairment charges in the future, which could have a materially adverse impact on Alcon's results of operations and financial condition.

| New standards and interpretations not yet adopted | New standards and interpretations not yet adopted In April 2024, the IASB issued IFRS 18, Presentation and Disclosure in Financial Statements, which will replace IAS 1, Presentation of Financial Statements and accompanies limited amendments to other standards which will be effective upon the adoption of the new standard. IFRS 18 will be retroactively effective for our annual reporting periods beginning on January 1, 2027, with early adoption permitted. The standard is expected to improve comparability and transparency of financial statements by requiring defined subtotals in the Consolidated Income Statement, requiring disclosure of management-defined performance measures and adding new principles for aggregation and disaggregation of information. Alcon is currently evaluating the impact of this standard on its Consolidated Financial Statements. Other than previously described, as of June 30, 2025 there are no IFRS Accounting Standards, interpretations or amendments not yet effective that would be expected to have a material impact on Alcon upon adoption.
