Our mission at UCSF is to exercise the highest standard of surgical care using sound judgment and the latest techniques, to provide balanced information about all available surgical and non-surgical options, and to advance the field of vision correction surgery through research.

All of our attending surgeons are board-certified ophthalmologists who have undergone formal fellowship training in corneal and refractive surgery and who have extensive clinical experience in performing refractive surgery. Each surgeon is on the full-time faculty of the University of California, San Francisco, a leading referral center for the treatment of ocular diseases. Collectively, they have authored dozens of publications and have lectured extensively both nationally and internationally.
