 the U.S. Securities and Exchange Commission (SEC) our preliminary merger proxy statement. This comprehensive disclosure document includes information about the transaction and the special meeting of stockholders that STAAR will hold to seek adoption of the merger agreement. We have also commenced our submissions to antitrust regulators, with more expected in the coming days and weeks. We are also working to respond to your questions about the transaction. While we still have a lot of work to do on our integration planning efforts with Alcon, we are able to answer many of the questions you submitted, particularly regarding employee compensation and benefits matters. Earlier today, we posted to STAARNET a Q&A document with information that we hope will address most of your questions. We will continue to keep you updated as we progress toward the closing of the transaction. In the meantime, please refer to our public disclosures and employee Q&A documents for more information:

| • |     | Press release announcing transaction (link), issued on August 4. |

| • |     | Employee Q&A regarding merger with Alcon (link), posted on August 4. |

| • |     | Employee Q&A regarding compensation and benefits (link), posted on September 5. |

We continue to believe that joining forces with Alcon will create exciting career opportunities for STAAR team members and will make EVO ICLs more available to patients and surgeons worldwide. As I said before, this acquisition marks a new chapter of opportunity for STAAR, and the company is excited to embark on this journey. Please stay tuned for future updates, and please reach out with additional questions. Sincerely, Stephen C. Farrell Chief Executive Officer EMPLOYEE Q&A

Topic: Treatment of STAAR Employee Compensation, Benefits and Equity Awards Last updated: September 5, 2025 Employee Q&A:

| 1. | Will my compensation and benefits change during the transition period before the closing of the announced 
 merger with Alcon?                                                                                        |

| • |     | Until the merger with Alcon is completed (the “closing”), it is business as usual at STAAR. |

| • |     | Employee compensation and benefits programs are continuing as usual, subject to potential normal changes to 
 benefits as part of the annual open enrollment process.                                                     |

| • |     | STAAR and Alcon will continue to operate as two separate companies until the closing. |

| • |     | Enrollment periods will remain in place. |

| 2. | What will happen to my compensation and benefits after the closing of the merger?
