Paul S. Koch, MD

Cataract and Lens Implant Surgery, Refractive Surgery

Dr. Koch is a Founder and the Medical Director of Koch Eye Associates. His specialty is Cataract, Lens Implantation, and Refractive Surgery.

Dr. Koch has been named one of the Top 100 Ophthalmologists and one of the Top 15 Cataract Surgeons in North America by Ophthalmology Times. He has been cited in each issue of the Best Doctors in America. He has won many awards including the Mericos H. Whittier Foundation’s Lifetime Achievement Award, the American Academy of Ophthalmology’s Honor Award, the David Kelman Foundation’s Golden Hands Award, Cataract and Refractive Surgery Today’s Nordan Award, the Irish-American Ophthalmology Society’s Top-Gun Phaco Award, the Hoffer Award, (twice), and the International Film Festival of the American Society of Cataract & Refractive Surgery Award (four times). He was in the inaugural group of inductees into the Bishop Hendricken High School Hall of Fame.

Dr. Koch has written seven textbooks on eye surgery, six of them about cataract surgery, which are the standard reading materials for residency programs in the US and abroad, and one about corneal refractive surgery. He has also written many journal articles, book chapters, and specialty editorials. He is Medical Editor Emeritus of Ophthalmology Management Magazine.

He has helped popularize many advances in cataract surgery, including techniques that permit surgery to be performed comfortably without anesthetic injections, and with vision recovery beginning only a few minutes after the operation is completed.

Dr. Koch has been around for most of the major breakthroughs in refractive surgery. He was one of the first refractive surgeons in America, first performing keratomileusis (the original manual technique for what is now LASIK) in 1979, keratophakia in 1980, and radial keratotomy in 1983 (he is also a radial keratotomy patient himself). He was among the first phakic lens implant surgeons, being one of the original clinical investigators for the Artisan/Veriyse lens and an early international implanter of the Visian lens. He was also one of the first surgeons to use accommodating lens implants to correct presbyopia, as he was one of the original clinical investigators for the Crystalens.

Lately Dr. Koch has been developing new ways to treat glaucoma permanently and safely without eyedrops. He is one of the inventors of the technology leading to microcannulation of Schlemm’s Canal in order to perform Canaloplasty, the first glaucoma procedure to restore normal physiologic outflow to the eye’s drainage system.

Dr. Koch is local to this area. He grew up in West Warwick. His dad was Dr. Peter Koch, long-time anesthesiologist at Kent County Memorial Hospital.
