During conventional lens implant surgery, the eye surgeon implants a fixed focus plastic or silicone artificial intraocular lenses (IOLs). This lens allows the patient to see well only a single distance, typically far; for close-up vision, patients would require a pair of glasses. However, the CrystaLens has the unique ability to focus on objects at varying distances using the eye's internal muscle in a manner that mimics a youthful, flexible lens. This means that the CrystaLens can provide sharper vision without corrective glasses, potentially throughout a full range of vision.

Fixed focal point Corrects only distance vision Does not move in eye Glasses required |
Moving focal point - "accommodates" Full range of distance, intermediate, and near vision Uses eye's natural focusing mechanism Use of glasses is greatly minimized |
Standard (single-focus) lens implants do not have the ability to provide a full range of vision. Most people who have single-focus lens implants must wear glasses for middle and near vision. Similarly, most people over the age of 45 who have LASIK have a single range of vision, unless they have monovision: one eye treated for distance and one eye corrected for near vision. Monovision has its own set of limitations and may not be the answer for everyone. However, the CrystaLens is able to restore your eye's natural focusing ability by using a design that corresponds to the way the natural lens flexes and focuses.
The CrystaLens is implanted in a similar manner to other intraocular lenses. It can be implanted after the removal of the eye's natural lens using the same technique as modern cataract surgery. This means your surgery can performed on an outpatient patient basis and that you can resume your normal work and recreational activities within a couple of days.
The CrystaLens is intended and FDA Approved for the visual correction, secondary to the removal of a cataract, in adult patients with and without presbyopia. During the FDA Clinical Trials, it was discovered that:
98.4% of patients implanted with the CrystaLens accommodating lens in both eyes could pass a driver's test without glasses
100% could see intermediate (24" to 30") without glasses, the distance for most of life's activities
98.4% could see well enough to read the newspaper and the phone book without glasses
Some patients did require glasses for some tasks after implantation of the CrystaLens accommodating lens
Significantly more patients implanted with a CrystaLens (88.4%) could see better at all distances without glasses than patients implanted with a standard IOL (35.9%)
