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.
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.
When the ciliary muscle contracts, the lens thickens, becoming more curved for added magnification for clear near vision.
In a young eye, accommodation is essentially instantaneous and effortless.

When the ciliary muscle is relaxed, the lens flattens to enable clear distance vision.
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.
The ciliary muscle, ciliary zonules and lens capsule keep the lens suspended in its proper position inside the eye for clear vision.
In this fashion, an accommodating IOL can expand the range of clear vision after cataract surgery, providing better near vision without eyeglasses than what is possible with a conventional monofocal IOL procedure.
The Crystalens IOL and the Trulign Toric IOL are very similar in design and both correct presbyopia.
In a conventional IOL, the haptics are designed to keep the optical portion of the implant stationary, with no rotation or anterior/posterior movement that could affect vision.
