Accomodating all

The primary difference between these two FDA-approved accommodating IOLs is that the Trulign Toric IOL can correct astigmatism as well as nearsightedness or farsightedness.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.Crystalens and Trulign Toric are premium intraocular lenses (IOLs) that correct presbyopia as well as common refractive errors, enabling an expanded range of clear vision and a decreased need for eyeglasses after cataract surgery, compared with surgery performed with conventional IOLs.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.The purpose of an adaptation is to assist children in compensating for intellectual, physical or behavioral challenges.They allow children to use their current skills while promoting the acquisition of new skills.Crystalens and Trulign Toric accommodating IOLs are premium intraocular lenses and therefore cost more than conventional monofocal IOLs.

The ciliary muscle, ciliary zonules and lens capsule keep the lens suspended in its proper position inside the eye for clear vision.

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.

In an accommodating IOL, the haptics are designed to keep the IOL securely in place and prevent any rotational movement, but the legs are flexible in a way that allows the optical portion of the IOL to move slightly forward upon contraction of the ciliary muscle.

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.

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.
