The American Academy of Ophthalmology (AAO) estimates that as many as 50 million Americans will suffer from vision-impairing cataracts by the year 2050.Given the current estimate of Americans with cataracts is only 25 million, the AAO is clearly expecting a surge over the next 30 years.(If you think about this in comparison, most of those “readers” available off the shelf in Walgreens and CVS provide 1.25 to 2.5 diopters of focusing power.
Most monofocal IOL patients opt for distance vision, then use eyeglasses for near vision.
For those who want to potentially get rid of their glasses altogether, the multifocal implant caters to both distance and near vision.
At the 2015 American Academy of Ophthalmology (AAO) annual meeting, clinical results of 2-year ongoing studies of a new, fluid-filled, shape changing, accommodating IOL, Fluid Vision (Power Vision, Belmont, California), were presented.
The Fluid Vision accommodating IOL gave excellent binocular distance, intermediate, and near visual acuities in the study population evaluated, reported Louis Skip Nichamin, MD, medical director, Laurel Eye Clinic, Brookville, Pennsylvania.
(Check out a past post I wrote comparing monofocal vs.
multifocal IOLs.)The most common IOL chosen by patients is monofocal, which provides vision correction for one distance (near, medium or distance vision).
An ambitious IOL indeed, but probably one that’s quite a few years from becoming a viable alternative.

With these new IOLs, as the ciliary muscle contracts, the accommodative lens contracts with it, curving and thickening to allow for focusing up close. Essentially, an accommodative IOL is the closest thing to the natural lens of the eye.
The only accommodating IOL currently approved by the FDA is Bausch Lomb’s Crystalens.
