Dr. Colby Stewart attended St. Thomas High School in Houston, Kent Preparatory School in Kent, Connecticut and the University of Texas in Austin, before graduating from the University of Texas Ophthalmology residency program in Galveston in 1996. He completed a six-month fellowship in oculoplastic and reconstructive surgery before moving to Tennessee to join a private practice. In 1998 he became Board Certified by the American Board of Ophthalmology and was one of the first to be recertified in 2009.
Dr. Stewart spent 1997 through 2003 working exclusively in middle and east Tennessee, including cities such as Nashville, Cookeville, and Knoxville. He worked together with local eye care providers and optometrists. As their primary surgeon and he performed oculoplastic procedures, topical anesthetic cataract surgery, glaucoma procedures and a new form of refractive surgery called LASIK. In 1998 he was the first surgeon to perform LASIK surgery in Cookeville. He quickly became recognized across Middle Tennessee for his surgical skills and his contributions to laser and cataract surgery. Dr. Stewart developed tracking and nomogram software for his LASIK practice that many doctors, including Dr. Stewart, still use today to monitor LASIK outcomes, and to ensure that patients are appropriate candidates for this procedure. In 2004 Dr Stewart returned to his hometown to join his father and the Houston Eye Associates. During this time, he focused on improving his surgical skills and introducing new techniques to improve patient outcomes and experiences.
