Accommodating IOLs are used in two procedures: refractive lens exchange (RLE) if you do not have cataracts and refractive cataract surgery if you do.
They cannot be used to treat astigmatism, but you can choose to have a separate laser eye surgery procedure to address your astigmatism if you wish. S., only one brand of accommodating IOL is currently available: Crystalens.
Not every patient is a good candidate for the presbyopic intraocular lenses.
Your physician will discuss with you the appropriateness of these based on your individual visual needs and on your eye examination. Accommodating IOLs are also designed to provide a continuous range of vision for distance, intermediate, and near, eliminating or reducing patients’ dependence on reading glasses or bifocals.
The crystalline lens is located behind the iris (the colored part of your eye), and is controlled by the surrounding ciliary muscles.
The lens bends, flexes, thickens, and thins as you focus on objects near and far. The accommodation of the lens works to focus images on the retina, where the images are turned into chemical signals which are interpreted by your brain.

Your lens can also become clouded with cataracts or you may experience difficulty seeing near objects due to presbyopia.
Are both cataracts and age-related farsightedness (presbyopia) affecting your lifestyle?
If you answered yes to either of these questions, accommodating intraocular lens implants (IOLs) may be the solution you’ve been looking for.
The new crystalens® intraocular lens, approved by the FDA in 2003, actually bends and flexes much like your natural lens, giving patients near 20/20 vision, often without the use of prescription glasses or contact lenses.
Crystalens® has an excellent success rate of accommodating for near and far vision, literally giving many older patients the same visual acuity they had in their 20s.
