Carl Tubbs, MD

dr-tubbsDr. Carl Tubbs is a native of Washington State. He completed his medical training in Seattle, and then studied Ophthalmology at the University of Minnesota before finally completing a glaucoma fellowship at the University of Virginia in 1993. On completing training, he and his wife Christine moved to Stillwater, MN where they lived for 20 years while raising two wonderful boys. Eventually, family commitments and new opportunity brought them back west to Denver, returning to the mountain country that they both love.

An early adapter of technology, Dr. Tubbs has been active in glaucoma and lens implant research, and has learned and applied new skills such as novel microsurgery for glaucoma, injectable medications to lower eye pressure, new devices for measuring and managing glaucoma, and the utilization of cataract technologies including wave-front aberrometry ( ORA and Veryon)and laser cataract surgery (LensX). In addition, he is involved with writing medical device draft standards for ANSI (the American National Standards Institute), and also chairs the Medical Devices Division of Z80. Internationally, he serves as a Technical Advisory Expert (TAG member), helping to represent U.S. interests and opinions within the International Standards Organization (ISO) arena. Through the ISO, the safety and effectiveness of intraocular lens implants can be managed on an international level.

When not working, Dr. Tubbs is active with hiking, gardening, skiing and bicycling, and loves exploring the Denver environment with family. When the sky allows, he continues to enjoy astrophotography, imaging distant stars and other deep space objects as well as the planets, and learning about backyard astronomy and science. Teaching still remains important; he has instructed surgical techniques and glaucoma care to residents at the VA Medical Center over the past 2 decades, and continues to enjoy working with patients and other doctors in order to promote lifelong learning.
