Accomodating intraocular lenses
As the IOL moves forward during focusing effort, the optic may also flex slightly, adding to the eye's magnifying power for reading.
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.
When the focusing muscle relaxes (as the person looks across the room, for example), the accommodating IOL returns to its original position and provides for clear distance vision.
Some accommodating IOLs also have an optic (the central part of the IOL that focuses light) that can partially flex.
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.
