Dr. Ryan Mercer is a cornea and refractive-trained specialist who also manages other eye conditions (such as glaucoma and medical retina). Dr. Mercer implants several different types of lenses at the time of cataract and refractive lens exchange surgery including standard monofocal lenses, astigmatic lenses, and multifocal lenses (such as PanOptix and Synergy, among others).

In addition to laser cataract surgery, Dr. Mercer performs laser refractive surgery (PRK, LASIK, AK, LRI). Some near-sighted individuals who are not candidates for laser refractive surgery may still be candidates for an implantable collamer lens (ICL) surgery, which Dr. Mercer performs. Dr. Mercer is proficient in partial thickness corneal transplant surgery (DSEK, UT-DSEK, nano-DSEK) and full thickness cornea transplant surgery (PKP), in addition to other ocular surface procedures such as pterygium excision.

Dr. Mercer has years of experience treating dry eye syndrome where he believes in using a multimodal and tiered approach to addressing each subtype of dry eye syndrome. Finally, Dr. Mercer performs MIGS and laser procedures to address glaucoma, and administers eye injections that treat certain retinal conditions related to diabetes and macular degeneration.
