 for the                                                                                                     
 STAAR common stock within ten (10) business days of the written request of Alcon, provided that Alcon may make only one such request with respect to any public Acquisition Proposal, subject to certain exceptions. |

Prior to receipt of the Stockholder Approval, if STAAR receives a written Acquisition Proposal from a third party after August 4, 2025 that has not been withdrawn, the Board may, (x) effect a Recommendation Change or (y) only if the Acquisition Proposal did not result from STAAR’s material breach of its non-solicitationobligations, cause STAAR to terminate the Merger Agreement pursuant to the Superior Offer Termination Right, in each case if:

| • |     | the Board determines in good faith after consultation with its outside legal counsel and financial advisors that                                                                                             
 such Acquisition Proposal constitutes or would reasonably be expected to lead to a Superior Offer and that failure to take such action would be inconsistent with its fiduciary duties under applicable law; |

| • |     | (i) at least four (4) business days before making such a Recommendation Change or terminating the Merger                                                                                                                                          
 Agreement, STAAR provides to Alcon a written notice of its intention to make such Recommendation Change or terminate the Merger Agreement and (ii) during such four (4)-business day period, if requested by Alcon, has negotiated in good faith  
 with respect to any revisions to the terms of the Merger Agreement or another proposal to the extent proposed by Alcon such that the Acquisition Proposal would cease to constitute a Superior Offer (provided that any material modifications or 
 amendments to the terms of such Acquisition Proposal will commence a new notice period of two (2) business days); and                                                                                                                             |

| • |     | the Board determines in good faith after consultation with its outside legal counsel and financial advisors that                                                  
 such Acquisition Proposal constitutes a Superior Offer and that failure to take such action would be inconsistent with its fiduciary duties under applicable law. |

Additionally, at any time prior to receipt of the Stockholder Approval, other than in connection with an Acquisition Proposal, the Board may, in response to an Intervening Event (as defined in this section below) make a Recommendation Change if:

| • |     | the Board determines in good faith, after consultation with outside counsel and its financial advisor, that the 
 failure of the Board to take such action would be inconsistent with its fiduciary duties under applicable law;  |

| • |     | (i) at
