Our practice takes great pride in providing exceptional eye care and quality products. Our comprehensive examinations not only evaluate our patients’ vision, but also include an overall eye health assessment and evaluation of eye alignment, eye movements, focusing ability and more. We offer contact lens and corneal health examinations and fit specialty lenses including multifocal lenses and those for patients with astigmatism. For your convenience we stock many popular brands of contact lenses in the office. We diagnose, manage and treat many eye conditions such as infections, allergies, and dry eyes as well as eye injuries. Our cutting edge technology assists the doctors in the diagnosis and management of many eye diseases including glaucoma, macular degeneration, and diabetic eye disease. We also co-manage with skilled surgeons in the areas of cataract and LASIK surgery. Our goal is to provide our patients with healthy eyes and clear, comfortable vision from infancy through adulthood.
