Accomodating lenses

26-Jan-2017 21:02

This condition, which begins to affect most people in their forties, is called presbyopia.Presbyopia is the inability of your eyes to accommodate.The Crystalens® is an accommodating intraocular lens that, unlike a standard IOL, can treat both a person’s cataracts and presbyopia- loss of near and intermediate vision.You probably noticed in your forties that you started to lose some of your up-close vision and had to start wearing reading glasses.Like the lens of a camera, the eye’s natural lens can change its focus and allow us to see objects up close, a process called “accommodation.” During cataract surgery, the natural lens is replaced by an artificial lens, and traditionally these artificial IOLs have been limited to allowing clear vision at only one distance.This technology is known as a non-accommodating “monofocal” IOL.There are several types of multifocal lenses available today.Each is designed to give you clear distance vision, but can also give you clear intermediate and near vision.

For example, you may find you are able to drive and see your dashboard, but have difficulty reading your grocery shopping list without glasses.

The unique Crystalens can reduce or eliminate glasses for most activities including: reading a book, working on the computer, and driving a car. Like the natural lens, it uses the eye muscle to flex and accommodate in order to focus on objects in the environment at all distances.

Crystalens dynamically adjusts to your visual needs.

In addition, if you have an astigmatism, you must have it corrected in order to maximize the benefit of these lenses. The design of the lens that allows you to focus at multiple distances can also create halos around and glare from lights.

Otherwise, you will not achieve your maximum level of glasses independence. Mostly, this affects patients at night when they are driving.
