A cataract is the clouding of the lens of the eye that obstructs the passage of light. The human eye is much like a camera, and needs a clear lens to focus light on the retina. (The retina is the back of the eye, where images are focused- like the film in a camera.)
Cataracts Allentown


A cataract forms when proteins in the lens of your eye clump together, forming opaque clusters- like dark smudges on a camera lens. Over time, these proteins can cloud the lens, allowing less light to pass through and degrading vision. Left untreated, cataracts can cause a complete loss of vision.



Patient Testimonial

“I had laser cataract surgery and chose the ReStor ocular lens. I have had a truly remarkable outcome. I have amazing visual clarity. My vision is 20/20 near to far. As someone who has worn glasses and contacts since the age of 9, I never imagined I would be able to have such perfect vision. The experiences in the office and the surgery center were great. The staff was warm and inviting. The surgery team made me feel safe and comfortable. Dr. O’Brien has a caring, positive and welcoming approach which gave me great comfort in asking questions and confidence in her expertise.”
