When you are facing a complex eye condition, finding the right medical team is the most important decision you will make. While routine eye exams are essential for maintaining prescriptions for glasses or contacts, serious ocular diseases require a higher level of expertise. For patients living in Greater Boston and MetroWest Massachusetts, navigating the healthcare landscape to find that level of care can sometimes seem overwhelming.
At the Massachusetts Eye Research and Surgery Institution (MERSI), we bridge the gap between standard vision care and high-level academic medicine. Located conveniently in Waltham, MERSI serves as a regional destination for patients seeking advanced treatment for uveitis, retinal disorders, glaucoma, and cataracts without the hassle of navigating downtown Boston.
What Is Specialized Eye Care?

Specialized eye care refers to medical and surgical treatment provided by ophthalmologists who have undergone additional, rigorous training in a specific area of the eye. Unlike a general eye exam which focuses on visual acuity, specialized care involves the diagnosis and long-term management of disease.
How Specialized Eye Care Differs From Routine Exams
Many patients confuse optometry with ophthalmology. While optometrists are vital for primary vision care and corrective lenses, specialized ophthalmologists are medical doctors (MDs) capable of performing delicate surgeries and managing systemic diseases that affect the eyes.
At MERSI, our physicians are fellowship-trained. This means that after medical school and residency, they completed additional years of study dedicated to subspecialties like the retina, cornea, or ocular inflammation. This depth of knowledge is essential for preserving vision in complex cases where standard treatments may fail.
Conditions That Require Specialized Attention
If you have been diagnosed with a condition that threatens your sight, you likely need more than a general check-up. We frequently treat patients presenting with:
-
- Retina and Macular Diseases: Including diabetic retinopathy, macular holes, and age-related macular degeneration (AMD).
- Glaucoma: A group of eye conditions that damage the optic nerve, often requiring laser or surgical intervention.
- Inflammatory Eye Conditions: Such as uveitis and scleritis, which often require systemic medication and careful monitoring.
- Complex Cataracts: Cases that may be complicated by other pre-existing eye diseases.
