Professional Statement

My work focuses on providing outstanding the outcomes of cataract surgery and improving the field through our extensive research activities. Best outcomes with cataract surgery require many elements: 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 cataract and intraocular lens problems, including inaccurate outcomes and poor quality of vision. I conduct research and teach physicians around the world in these areas.

Skills

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: 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.
