Sight Surgery International provides free eye surgery and educational ophthalmic skills enhancement around the world.  The next clinic will be in San Salvador, El Salvador at the invitation of the Salvadorian Ophthalmological Association.  The Association has requested Brown to coordinate a "Cataractathon" where Association members all donate part of a week doing free eye surgery for patients who could not otherwise afford cataract surgery. SSI will provide overall coordination, surgical supplies and multiple surgical instrument sets.
