For many cataract patients, multifocal intraocular lenses have worked well and have afforded them a broader range of vision postoperatively.

For others, though, the possibility of glare, halo and other qualitative vision problems has led them to shy away from multifocal lenses and stick with monofocal options.

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.

This is why they are classified as "accommodating IOLs." Both lenses are manufactured and distributed by Bausch Lomb.

Cataract removal is the most common surgical procedure in the United States, with nearly 3 million operations performed annually.

This number will likely grow, according to National Eye Institute statistics that predict an increase in the number of people in the United States with cataracts from the current level of 20 million to more than 30 million by the year 2020.

There are some lenses, however, that aim to bridge the gap between multifocals and monofocals and allow more vision at different distances while minimizing visual side effects.

Recent advances in pseudoaccommodative multifocal IOL technology offer a new alternative for those desiring vision at both distance and near.He said he had a patient who had a Re STOR lens in one eye and was getting the Crystalens in the other eye.The patient was a minister who needed to have excellent intermediate vision because he stands at a podium to speak and is on the computer often. Horn described, “I noticed when I was sitting talking to him that he was reading a list of questions but the questions were on his lap. And I saw that he was reading them with his Re STOR eye that I had just operated on because his other eye was still hyperopic so he couldn’t have been reading it with that eye.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.In June 2014, AMO received the CE Mark to market the Tecnis Symfony Extended Range of Vision IOL in Europe.
