Partner with MERSI to Better the World's Vision.

We offer immediate access to appointments.
Patients no longer have to wait weeks to see a specialized ophthalmologist. Here at MERSI, we offer immediate access to appointments, a 24-7 on call doctor and monthly Saturday hours. This is crucial for patients with uveitis and ocular inflammatory disease.

We treat a wide range of diseases and conditions.
We provide modern diagnosis and treatment of eye problems including but not limited to cataract, glaucoma, dry eye, uveitis, diabetic eye care, macular degeneration, as well as general eye care. Dr. Foster brings over 40 years of experience, and has trained both Dr. Anesi and Dr. Chang with his expertise.

We offer the latest advances in technology.
Technology is increasingly changing the healthcare industry and MERSI intends to always have the most revolutionizing products in the industry. MERSI was designed to allow for “one-stop-shopping” with exams, testing, surgery and treatments all under one roof. Our onsite infusion suite, and blood and pathology labs provide enhance diagnostic and treatment capabilities. All testing is reviewed and interpreted on the same day as visit. We also offer the latest advancements in cataract surgery and care.

We always work to give patients the most pleasant experience possible at MERSI, from the moment of check in to departure. Our staff is trained in the philosophy that the patient always comes first. Our revolutionary technology also helps with patient flow and performance optimization, resulting in more efficient patient visits.
