Presbyopic Lens Exchange
PRELEX corrects nearsightedness, farsightedness, and presbyopia, using a multifocal intraocular lens implant. PRELEX my be the procedure of choice for patients who are too nearsighted, too farsighted, or have corneas that are too thin for laser vision correction. It is also a viable alternative for those over the age of 40 who wish to eliminate their dependence on bifocals or reading glasses and for those individuals who may be showing signs of developing cataracts.
In contrast to monofocal lens implants that provide excellent vision at one point of focus, multifocal lens implants provide a full range of clearer vision at multiple distances: near, intermediate, and distance, thereby allowing a person to perform most of their daily activities with reduced or no dependence on glasses. Having multifocal lenses implanted in both eyes proved the added advantage of binocular vision and improved depth perception at multiple distances.
Millions of eyes have received intraocular lens implants when undergoing cataract surgery, using the same highly successful surgical techniques used in PRELEX.
Performed as an outpatient procedure, the natural lens is removed through a very small micro-incision and replaced through that same incision with the multifocal intraocular lens. You will remain comfortable as the eye is completely anesthetized with numbing eye drops. Everyone heals differently, but many patients report improvement in their vision almost immediately, and most resume their normal activities within a day or two. One eye is done at a time, and the second eye is usually done in a week or two.
