Carter Eye Center in Dallas, Texas

Crystalens® is an Accommodating Intraocular Lens (IOL) that differs from other IOLs. Because it is controlled naturally, using your eye muscles, it is able to move and accommodate vision to see at variable distances. It is a wonderful corrective solution for both presbyopia and cataracts. Although presbyopia and cataracts are two entirely different anomalies of the eye, they both involve the ocular lens.

In presbyopia, the lens loses its ability to accommodate or change its shape to focus clearly between near and far. This is a normal aging effect and is seen most often in people over 40. It generally affects both eyes.

Cataracts are clumps of protein whose density creates a cloudy area in the lens that blurs vision. Cataracts can occur in one or both eyes, and can result from aging or from trauma to the eyes. In the case of trauma, cataracts may develop earlier in life.

Crystalens® IOLs are implanted, replacing the natural lens. This procedure attaches the IOL to the eye muscles and allows these muscles to move the lens to accommodate focus changes between near and far vision. A recent improvement to Crystalens® is the FDA approved HD model that provides better contrast sensitivity and depth of focus. Most patients can see well at all focal ranges without the need for glasses, at all. Read more about Crystalens®.

Dr. Harvey Carter of the Carter Eye Center in Dallas was the first U.S. surgeon to implant Crystalens® after the FDA approved its use, and has performed more Crystalens® implants than any eye surgeon in the world.
