When you are facing a complex or sight-threatening eye condition, selecting the right medical team is the most vital decision you will make. While routine eye exams with a local optometrist are essential for updating prescriptions for glasses or contact lenses, serious ocular diseases require a significantly higher tier of medical expertise.
For patients living in Andover, Massachusetts, and the surrounding Merrimack Valley, navigating the healthcare landscape to find university-level care often means facing the traffic and logistical headaches of downtown Boston. However, there is a superior alternative.
At the Massachusetts Eye Research and Surgery Institution (MERSI), we bridge the gap between standard vision care and high-level academic medicine. Conveniently located in Waltham, MERSI serves as a premier regional destination for Andover residents seeking advanced treatment for uveitis, retinal disorders, glaucoma, and cataracts, without the stress of city driving.
What Is Specialized Eye Care?

To understand why patients travel from Andover to MERSI, it is important to understand the distinction between general eye care and specialized medicine. Specialized eye care refers to medical and surgical treatment provided by ophthalmologists who have undergone rigorous, additional training in specific areas of the eye.
Unlike a general eye exam, which focuses largely on visual acuity (how well you see), specialized care involves the diagnosis, treatment, and long-term management of disease (the biological health of the eye).
How Specialized Ophthalmology Differs From Routine Optometry
Many patients confuse optometry with ophthalmology.
-
- Optometrists are vital for primary vision care, annual check-ups, and corrective lenses.
- Ophthalmologists are medical doctors (MDs) capable of performing delicate surgeries and managing systemic diseases that affect the eyes.
At MERSI, our distinction goes even further: our physicians are fellowship-trained. This means that after medical school and residency, our doctors completed additional years of intensive study dedicated to subspecialties like the retina, cornea, or ocular inflammation (uveitis). This depth of knowledge is essential for preserving vision in complex cases where standard treatments have failed.
Conditions That Require Specialized Attention

If you have been diagnosed with a condition that threatens your sight, you require more than a general check-up. We frequently treat patients from the Andover area presenting with:
-
- Retina and Macular Diseases: Including complex diabetic retinopathy, macular holes, retinal detachments, and age-related macular degeneration (AMD).
- Glaucoma: A group of serious eye conditions that damage the optic nerve, often requiring advanced laser or surgical intervention to prevent blindness.
- Inflammatory Eye Conditions: Such as uveitis, scleritis, and ocular cicatricial pemphigoid, which often require systemic chemotherapy or biologic medication and careful, long-term monitoring.
- Complex Cataracts: Surgical cases that may be complicated by other pre-existing eye diseases or prior surgeries.
- Dry Eye Syndrome: Severe cases that have not responded to over-the-counter treatments or standard prescription drops.
Why Andover Patients Choose MERSI

MERSI was founded on a dual commitment to patient-centered care and academic excellence. Our facility allows us to offer university-level medicine in a private practice setting. For residents of Andover, North Andover, and Methuen, MERSI offers a unique combination of accessibility and world-class expertise.
1. Renowned Fellowship-Trained Specialists
Our team includes recognized leaders in the field of ophthalmology. Dr. Stephen D. Anesi and Dr. Peter Y. Chang, along with associates Dr. Peter L. Lou and Dr. Carl S. Wilkins, bring a powerful combination of expertise to the practice. Having trained hundreds of eye surgeons and ocular immunologists worldwide, our institution remains at the forefront of ophthalmic research.
Whether you require a vitreoretinal surgeon or an expert in ocular immunology, our partners work collaboratively to ensure every aspect of your eye health is addressed under one roof.
2. Commuter Advantage: Avoiding Boston Traffic
One of the significant advantages of choosing MERSI is accessibility. While Boston is a global hub for medicine, accessing hospitals in the city center often involves unpredictable traffic, expensive parking garages, and long wait times.
For a patient coming from Andover, the drive to Waltham is often faster and less stressful than navigating into the Longwood Medical Area or Mass General. Located just off Route 128 / I-95, MERSI is easily accessible via I-93 and I-95. We offer free parking and full handicap accessibility, removing the logistical stress often associated with medical appointments.
3. Integrated Advanced Technology
We believe in a “one-stop” approach to care. To reduce the burden on our patients, we have integrated state-of-the-art technology directly into our Waltham facility.
-
- Diagnostic Testing: We offer optical coherence tomography (OCT), fluorescein angiography, and visual field testing with same-day interpretation. You won’t have to wait days for results.
- Infusion Suite: For patients with inflammatory diseases requiring biologic therapies (like Remicade or Humira), our on-site infusion suite offers a comfortable environment staffed by skilled nurses.
- Pathology Lab: We house a CLIA-certified diagnostic immunopathology laboratory for ocular tissue, ensuring rapid and accurate diagnosis without sending samples off-site.
Specialized Services Offered
Our comprehensive eye care center addresses diagnostic and therapeutic needs across several key subspecialties.
Retina & Macular Disease Care
Our fellowship-trained surgeons provide management for vitreoretinal disorders. This includes cutting-edge treatments for both wet and dry AMD.
-
- Valeda Light Therapy: MERSI offers Valeda, the first FDA-authorized light therapy specifically for dry AMD.
- Susvimo Implants: Our team of doctors is experienced in implanting Susvimo for wet AMD and diabetic macular edema, offering continuous drug delivery.
Glaucoma & Cataract Services
We utilize the latest technology for preserving vision. This includes Femtosecond Laser surgery for cataracts, offering a level of precision not always achievable with traditional manual techniques. For glaucoma patients, we perform various procedures ranging from laser iridotomy to advanced MIGS (Minimally Invasive Glaucoma Surgery) and valve-tube surgery.
Ocular Immunology (Uveitis & Scleritis)
As a center globally renowned for ocular immunology, we specialize in the long-term management of uveitis and scleritis. These conditions often require a delicate balance of medication (immunomodulatory therapy) and surgery. Our doctors work closely with rheumatologists and other specialists to manage the patient’s overall systemic health, ensuring a holistic approach to eye care.
What to Expect as a New Patient
We understand that visiting a specialist can be stressful, especially if you have received a concerning diagnosis. Our goal is to make your experience as pleasant and efficient as possible.
Rapid Access to Appointments
MERSI prides itself on offering immediate access to appointments. Unlike many academic centers where wait times for specialists can be months long, we strive to see patients quickly. This is an essential factor when dealing with aggressive inflammatory diseases or retinal conditions where time is of the essence.
While many patients are referred by their local Andover optometrist or general ophthalmologist, you can also contact our office directly to discuss appointment availability.
Coordinated Care with Your Local Doctors
When you become a patient at MERSI, we become partners in your health. We promptly send detailed reports of your consultation to your referring doctor in Andover or the Merrimack Valley to ensure continuity of care.
