MERSI physicians perform the following surgical procedures:


The most advanced cataract surgery available: small incision, sutureless, with topical anesthesia per patient preference, employing state-of-the-art intraocular lens implants, especially those best tolerated for patients with a history of uveitis and/or glaucoma. Our surgeons also offer the latest Premium Lifestyle lenses.

Laser Cataract Surgery

Femtosecond Laser now offers patients the new standard in precision cataract surgery with the CATALYS Precision Laser System. Using CATALYS, the surgeon can provide a gentle, highly customized cataract procedure with precision not achievable with traditional manual techniques.  This allows patients the opportunity to receive tailored treatment with advanced technology multi-focal lenses, which may reduce the need for glasses or contacts after surgery.


Amniotic membrane grafting, anterior segment, reconstruction, corneal transplantation, keratoprosthesis, pterygium excision, and limbal stem cell transplantation for ocular surface reconstruction are all performed on an ambulatory outpatient basis.


Glaucoma laser surgery, trabeculectomy filtering surgery, express shunt, endoscopic cyclophotocoagulation (ecp) and valve-tube surgery performed on an ambulatory outpatient basis.


Diagnostic and therapeutic pars plana vitrectomies with and without endolaser or epiretinal membrane peeling for patients with uveitis, diabetic retinopathy, retinal detachments, or epiretinal membranes are performed on an ambulatory outpatient basis. Admission may be required depending on the complexity of the case, which may also apply to scleral buckling or other vitreo-retinal surgeries.
