About Me

Dr. Ryan Mercer is a cornea and refractive-trained ophthalmologist who offers a full range of vision-correcting procedures alongside comprehensive eye care. He performs laser cataract surgery and implant options including astigmatism-correcting and multifocal lenses, and provides LASIK, PRK, and implantable collamer lens (ICL) surgery for patients who want to reduce their dependence on glasses or contacts. He also treats keratoconus with crosslinking and performs partial- and full-thickness corneal transplants. Dr. Mercer takes time to understand each patient’s visual goals, explains options in plain language, and builds a plan to maximize both quality of vision and long-term eye health. He manages dry eye with a stepwise approach and offers minimally invasive glaucoma procedures (MIGS) when appropriate, coordinating closely with referring providers to ensure smooth, timely care.
