Refractive Lens Exchange

RLE

Refractive lens exchange, also called clear lens extraction, replaces the natural lens with a multifocal intraocular lens (IOL) in patients wishing to correct high farsightedness, high nearsightedness, or presbyopia without undergoing a corneal modification procedure such as LASIK. Patients can choose from a wide range of IOLs in order to achieve the best possible vision for their individual eyes.

The refractive lens exchange procedure is the same that is used in cataract surgery. The only difference is that refractive lens exchange is performed to achieve refractive correction rather than cataract removal. Refractive lens exchange involves a rapid recovery and offers patients dramatic improvement in vision quality.

Corneal Transplant Surgery

The cornea is the clear covering of the front of the eye which bends, or refracts, light rays as they enter the eye. For clear vision to occur, the cornea must have the correct shape and clarity to focus incoming light rays precisely on the retina at the back of the eye. When the cornea becomes cloudy or misshapen from injury, infection or disease, transplantation may be recommended to replace it.

Corneal transplants are usually performed with local anesthesia so there is no pain. During the procedure, the cornea is replaced with one from a human donor. The new cornea carries little risk of rejection and can last for many years.

AcrySof ReSTOR® Intraocular Lens

The AcrySof ReSTOR® Intraocular Lens replaces the natural lens after cataract surgery using advanced apodization, diffraction, and refraction technologies. Its design allows it to focus light correctly on the retina for both near and far distances without mechanical movement. Clinical studies have shown that this lens provides good near and distance vision, increasing independence from glasses.
