proposal necessary to consummate the Merger (the “Merger Proposal”). As disclosed by STAAR on a Current Report on Form 8-K filed on October 27, 2025, STAAR announced that, in light of ongoing
discussions with Alcon, the Special Meeting, which had previously been adjourned to November 6, 2025 at 8:30 a.m. Pacific Time, has been postponed to December 3, 2025 at 8:30 a.m. Pacific Time. The record date for the Special Meeting,
which was previously September 12, 2024, has been reset to be the close of business on October 24, 2025 (the “Record Date”). Stockholders who hold shares as of the Record Date will be eligible to vote at the postponed Special
Meeting on December 3, 2025.

The Special Meeting will be held in a virtual meeting format only. Stockholders who wish to attend the
virtual Special Meeting on December 3, 2025 may access the meeting via the following link:www.virtualshareholdermeeting.com/STAA2025SM.
