A most accomodating

This is why they are classified as "accommodating IOLs." Accommodation is made possible by the lens inside the eye and the circular muscle that surrounds the lens, called the ciliary muscle.

The lens and ciliary muscle are connected by a 360-degree series of fibers (called ciliary zonules) that extend from the ciliary muscle to the thin lens capsule (or "bag") that encloses the lens.

When the ciliary muscle is relaxed, the lens flattens to enable clear distance vision.

In a young eye, accommodation is essentially instantaneous and effortless.

As the eye ages, the lens becomes less flexible, causing the loss of near vision that is the hallmark sign of presbyopia in people over age 40.

Currently, Crystalens and Trulign Toric IOLs are the only FDA-approved presbyopia-correcting IOLs for cataract surgery that improve near vision by a focusing process called accommodation.

During cataract surgery, a circular opening is cut in the anterior part of the lens capsule so the surgeon can remove the eye's natural lens that has become cloudy. The peripheral and posterior portions of the lens capsule are left intact, forming a partially open "bag" that the intraocular lens is positioned within to restore focusing power to the eye.

All IOLs have a central optical zone, with peripheral "legs" (called haptics) that secure the lens implant inside the lens capsule.The ciliary muscle, ciliary zonules and lens capsule keep the lens suspended in its proper position inside the eye for clear vision.In a normal eye (without presbyopia or cataracts), this dynamic process of accommodation adjusts the focusing power of the eye by changing the thickness of the eye's natural lens.Though Crystalens and Trulign Toric accommodating IOLs provide an expanded range of clear vision compared with conventional monofocal intraocular lenses, you may still need reading glasses to comfortably see small print and perform other near vision tasks.That said, most people who choose one of these accommodating IOLs are very pleased with the greater freedom from eyeglasses they have after cataract surgery.Also, the added cost of these presbyopia-correcting IOLs typically is not covered by Medicare or private health insurance.
