Crystalens accommodating iol patients conventional

Currently, Crystalens is the only accommodating IOL that is FDA-approved for use in refractive or cataract surgery in the United States.

(The only difference in the two procedures is that in cataract surgery the natural lens that is removed is cloudy, and in refractive lens exchange the removed lens is still clear.) The actual surgery takes approximately 15 to 20 minutes, and it is performed as an outpatient procedure under local anesthesia.

So you are awake during the procedure and can go home as soon as the surgery is finished.

Most people can return to their normal routine the day after surgery and can see well enough to function without glasses almost immediately.

However, it can take several months before a person fully adapts to multifocal vision with the Crystalens IOL and attains the best vision possible with the lens implant. Crystalens HD represents the fourth generation of Crystalens IOLs, replacing the Crystalens Five-O model, which was used implanted into the eyes of over 100,000 patients.

In July 2008, Bausch & Lomb introduced its new Crystalens HD to the U. The optic (the central portion of the lens that corrects vision) of the new Crystalens HD offers an enhanced depth of focus and is designed to improve near vision without compromising intermediate or distance vision or inducing glare or night vision problems, says Bausch & Lomb.

In the clinical study required for FDA approval, the Crystalens HD was implanted in 125 eyes of patients who had a visually significant cataract, less than 1.00 diopter of corneal astigmatism, and the potential for best corrected visual acuity (BCVA) of 20/25 or better in both eyes.

Of the 67 subjects who were within ± 0.50 D of intended target, 80 percent achieved the equivalent of 20/20 or better reading vision within six months of surgery.

Crystalens is an accommodating IOL designed to correct presbyopia as well as nearsightedness and farsightedness.

This premium intraocular lens can be inserted in the eye as part of refractive cataract surgery for people who already have cataracts, or it can be used in refractive lens exchange (RLE) for people who don't yet have cataracts and wish to have lens-based vision correction surgery with little or no need for reading glasses after surgery.

Crystalens does not correct astigmatism, but if residual astigmatism remains after the Crystalens procedure, it can be eliminated with one of several other refractive surgery options, including standard LASIK, wavefront LASIK (also called custom LASIK), or PRK surgery.
