, are entitled to vote at the meeting. In conjunction with the definitive proxy filing, STAAR is mailing the following letter to STAAR stockholders: Dear Fellow Stockholders, On August 5, 2025, we announced that STAAR Surgical Company entered into a definitive merger agreement to be acquired by Alcon for $28.00 per share in cash. STAAR will hold a virtual Special Meeting of Stockholders on October 23 at 8:30 a.m. (Pacific Time) to ask for your vote to adopt the merger agreement. The STAAR Board of Directors unanimously determined that the proposed merger with Alcon is in the best interests of STAAR and its stockholders and strongly recommends that you vote “FOR” the merger proposal, as described in the accompanying proxy statement. $28.00 per share is a compelling premium on multiple measures:

| ~51% Premium to closing stock   
 price day prior to announcement |     | ~59% Premium to 90-day VWAP |     | Significantly Higher Premium                                   
 compared to the 26% median for comparable MedTech transactions |     | 47% Premium to median sell-side            
 price targets prior to merger announcement |

We believe the value provided by the Alcon merger exceeds what STAAR could achieve on a standalone basis in the foreseeable future, particularly given STAAR’s lower growth rate and the resulting impact on its valuation, and the substantial competitive and macro challenges in the markets STAAR serves. Our business is heavily exposed to China, which faces significant economic uncertainty and where sales trends have been declining despite actions taken by the Company. Notably, STAAR’s common stock closed at only $18.49 per share just prior to the announcement of the Alcon agreement. Vote “FOR” the Merger Proposal TODAY Your vote is importantbecause the merger is subject to approval by the holders of a majority of STAAR’s outstanding shares of common stock. Failure to vote will have the same effect as an “AGAINST” vote.To help ensure you receive the compelling, premium $28.00 per share cash value afforded by the Alcon merger please vote “FOR”the merger proposal TODAY.
