View Curriculum Vitae


D. Rex Hamilton, MD, is the Director of the UCLA Laser Refractive Center and Clinical Professor in the Cataract and Refractive Surgery Division at the world renowned Stein Eye Institute. He is highly trained in laser vision correction and advanced refractive cataract surgery. He has pioneered new techniques at the Eye Institute, in Los Angeles and the West Coast of the U.S. In 2004, Dr. Hamilton was the first surgeon at the Stein Eye Institute to implant an accommodating intraocular lens to restore focusing power to an aging eye. In 2010, Dr. Hamilton was the first surgeon at Stein Eye Institute to perform laser-assisted cataract surgery. Most recently, in 2017, Dr. Hamilton was the first surgeon on the West Coast to perform the refractive procedure SMILE (Small Incision Lenticule Extraction).

After graduating Phi Beta Kappa and Summa Cum Laude from Dartmouth College with an undergraduate degree in physics and mathematics, Dr. Hamilton pursued an advanced degree in biomedical engineering. With his highly technical background, Dr. Hamilton is a true physician scientist. Dr. Hamilton continued his education at the University of California, Irvine, where he earned a doctor of medicine degree and received numerous academic awards and scholarships, culminating in his graduation at the top of his class. He began performing refractive and cataract and corneal transplantation refractive surgery during his residency training at the Stein Eye Institute. Following the completion of his residency, Dr. Hamilton completed a one-year fellowship in refractive, cornea, anterior segment, cataract and glaucoma surgery at Minnesota Eye Consultants under the directorship of Dr. Richard Lindstrom, uniformly recognized as one of the founding fathers of modern cataract and refractive surgery. He then returned to the Stein Eye Institute, where he became and still is, the Medical Director of the UCLA Laser Refractive Center.

Dr. Hamilton is actively involved in clinical research, particularly in the area of premium (multifocal and toric) intraocular lenses for cataract surgery, corneal biomechanics and imaging. He has authored 40 peer-reviewed journal articles and book chapters, given more than 50 scientific presentations at national meetings and has delivered more than 150 invited lectures across the country and internationally. He has served on the American Academy of Ophthalmology’s Preferred Practice Pattern Committee for Refractive Surgery. He currently serves on the Refractive Surgery Clinical Committee and Refractive/Cataract Clinical Subcommittee for the American Society of Cataract and Refractive Surgery. Recognized for his contributions to the field, he was elected to Marquis Who’s Who in Medicine and Healthcare, 4th Edition and Who’s Who in Science and Engineering, 7th Edition. He is a member of the American Academy of Ophthalmology, American Society of Cataract and Refractive Surgery, and the International Society of Refractive Surgery.
