TedX with Dr. Levenson

In November 2017, Dr. Levenson gave an illuminating talk at TEDx Santa Barbara. Jeff shared the story of how his life changed dramatically when he started losing his sight to cataracts. Once he received the treatment he needed to regain his sight, he became passionate about restoring sight to those without access to eye care. To do so, he needed to learn a different cataract surgery method that did not involve the technology commonly used in the United States.

Jeff reached out to SEE to learn the technique, known as Manual Small-Incision Cataract Surgery, or MSICS, which is critical to treat cataracts in humanitarian settings. Now an expert in the procedure, Dr. Levenson volunteers treating with SEE regularly, giving the gift of sight to those in need.
