Dr. Merkley serves as the Chair of the Department of Ophthalmology and Visual Sciences at UTMB. Dr. Merkley, with more than 25 years of experience as a cataract, cornea and refractive surgeon, he treats a wide range of eye conditions, including cataracts, glaucoma, cornea/external disease, diabetic eye disease, macular degeneration, and refractive errors. "The exciting thing about refractive surgery is that new technologies continue to come forward as older technologies continue to improve. This will allow us to treat an increasingly wide spectrum of patients and refractive errors with even more predictable outcomes than we have enjoyed in the past."
