Another option is a non-laser procedure called limbal relaxing incisions.

Accommodating IOLs can be used in refractive cataract surgery for cataract patients or they can be used in refractive lens exchange (RLE) for people who don't have cataracts, but want lens-based vision correction surgery to reduce the need for reading glasses.

A realistic expectation is that you will be less dependent on reading glasses after accommodating IOL surgery, and that you will be able to read and see many things up close better than you could prior to surgery without bifocals or reading glasses.

In some cases, an accommodating IOL may be properly implanted, but the ciliary muscle or the zonules attaching the lens capsule to the muscle may no longer function properly.

In these cases, an accommodating IOL may not be able to improve near vision, but it will still function well as a monofocal (single power) IOL for good distance vision.

Accommodating IOLs are premium intraocular lenses and cost significantly more than conventional IOLs.

Currently available accommodating IOLs do not correct astigmatism, but several options exist for the correction of astigmatism after accommodative IOL surgery, including standard LASIK, custom LASIK (also called wavefront LASIK), PRK, and other laser vision correction procedures.

As the IOL moves forward during focusing effort, the optic may also flex slightly, adding to the eye's magnifying power for reading.

Candidacy for accommodating IOL surgery is determined using the same criteria used to determine candidacy for either refractive cataract surgery or refractive lens exchange.

If you choose to have an accommodating IOL implanted during cataract surgery, you typically will have to pay the difference between the cost of the accommodating IOL and the amount your insurance plan allows for the cost of a conventional IOL. Currently, only one brand of accommodating IOL is FDA-approved for use in the United States — the Crystalens accommodating IOL produced by Bausch & Lomb (Rochester, NY).

However, other brands are currently being clinically tested and may be available soon.
