Services
Comprehensive Eye Exams
Our detailed eye examinations use advanced diagnostic technology to assess vision health and detect early signs of ocular disease. The process includes refraction testing, intraocular pressure measurement, and retinal imaging. Patients receive personalized recommendations for vision correction and eye health maintenance.
Dry Eye Treatment
We offer specialized treatments for chronic dry eye syndrome using advanced therapies like TearCare and PROKERA devices. Our approach combines diagnostic testing with customized treatment plans that may include prescription drops, nutritional supplements, and lifestyle modifications to improve tear production and quality.
Scleral Lenses
Custom-designed rigid gas permeable lenses provide vision correction for patients with keratoconus and other corneal irregularities. These large-diameter lenses vault over the cornea, creating a fluid reservoir that improves visual clarity while providing comfort for sensitive eyes.
Myopia Management
Our evidence-based programs slow the progression of nearsightedness in children through specialized contact lenses and orthokeratology. Treatment plans include regular monitoring of refractive changes and personalized interventions to reduce long-term risks of severe myopia and associated eye diseases.
Emergency Eye Care
We provide immediate treatment for ocular injuries and sudden vision changes. Services include foreign body removal, corneal abrasion treatment, and management of acute eye infections. Our doctors are trained to handle urgent conditions that require prompt intervention to preserve vision.
