Charles Manger III, M.D.

Dr. Manger was appointed to the U.S. Naval Academy in Annapolis, Maryland by Senator Daniel K. Inouye of Hawaii, where he earned his Bachelor’s of Science degree in mathematics and nuclear science and graduated with honors. Dr. Manger then served in the Navy as an engineering officer on a nuclear missile submarine under Admiral Hyman Rickover for 5 years.

He then completed an internship and 3-year ophthalmology residency at the renowned Doheny Eye Institute in Los Angeles.

I decided a long time ago to limit my practice to LASIK only. I figured if LASIK was the only procedure I did, I’d probably do it better than anyone else.

As with all surgical procedures, there are risks that will be discussed with you prior to having your procedure. These risks include, but are not limited to fluctuating vision, visual symptoms like glare or haloes around lights, dry eyes that require eye drops, and the occasional need for a retreatment.
