Accomodating intraocular lenses
Accommodating IOLs are premium intraocular lenses and cost significantly more than conventional IOLs.
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).
The lens is held in place within the eye by fibrous strands, or zonules, which attach the outer capsule of the lens to the focusing muscle (called the ciliary muscle) that surrounds the lens.
Contraction and relaxation of the ciliary muscle changes the tension in the zonules, which in turn changes the shape of the lens to provide the correct focusing power for seeing objects at all distances.
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.
