Your cataract surgeon can help you decide if accommodating IOLs or multifocal IOLs are the right choice for your particular needs during your preoperative eye exam and consultation.

Crystalens and Trulign Toric accommodating IOLs are premium intraocular lenses and therefore cost more than conventional monofocal IOLs.

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.

Both categories or presbyopia-correcting lenses — accommodating IOLs and multifocal IOLs — have advantages and limitations.

Generally, while both designs expand the range of clear vision compared with conventional monofocal IOLs, accommodating IOLs tend to provide sharper distance vision than multifocal lenses, and multifocal IOLs tend to provide more magnifying power for seeing fine print than accommodating IOLs.

The Crystalens IOL and the Trulign Toric IOL are very similar in design and both correct presbyopia.

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.

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.
