Professional Statement

My work focuses on improving the outcomes of cataract surgery and refractive surgery procedures such as LASIK and PRK. It involves all aspects: careful measurement, individualized selection of the appropriate options for each patient, meticulous surgery, prevention of complications, and maximizing the final vision. I also specialize in the management of complex conditions including cataract and intraocular lens problems, iris repair and replacement, and management of LASIK and PRK problems. I conduct research and teach physicians around the world in these areas.

Cataract and intraocular lens surgery
Basic and complex cataract surgery including personalized selection of the best option for each patient, meticulous measurements, and management of the most complex cataract and intraocular lens problems.
Laser cataract surgery
I was involved in the early stages of the development of laser cataract surgery and find it to be a major advance for accuracy and safety for the appropriate patient.
LASIK and PRK offer the possibility of remarkable vision for the appropriate patient. I have been doing these procedures from the time of their early introduction and have been involved in many of the major clinical trials that have brought new advances. My major emphasis is quality of vision and safety for all patients.
Iris repair
I also specialize in surgical procedures to repair and replace the iris, including leading at Baylor a new trial of an artificial iris that is individually designed to match the patient's other eye. Results have been amazing.
