Accommodating IOLs Thus far, the only accommodating lens available outside of clinical trials is the Crystalens (Eyeonics); therefore much of the following text about surgical technique and clinical results will focus on this lens.

The Crystalens is designed to provide good vision at all distances by moving forward and backward along the axis of the eye.

Though they achieve the goal by different means, their purpose is to restore to patients the ability to accommodate at near, intermediate and distance vision.

The Eyeonics Crystalens has been on the market for two years.

There are a number of other accommodating IOLs in various stages of clinical trials or early research.

So far, none has been implanted in large numbers of humans.Release Date: July 2005Last Review Date: July 2005Expiration Date: July 2006Media: CME Monograph Estimated Time to Complete the Activity: 1 hour Sponsored by the Postgraduate Institute for Medicine.This activity is supported by an educational grant from Eyeonics Inc.Computers, personal organizers, cell phones and other devices that require intermediate vision have become so pervasive in our society that good intermediate vision is at least as important now as reading vision.A true accommodating lens attempts to have a similar mechanism of action to the human lens, with the ability to focus near, far and at every point in between, just as the young human lens can.This activity has been planned and produced in accordance with the ACCME Essential Areas and Policies.
