Crystalens may be an appropriate alternative to monovision for some patients.
As we mature, the natural crystalline lens in the eye expands, firms, and loses its ability to accommodate from distance to midrange to near vision.
Crystalens is the brand name of an intraocular lens (IOL) that is designed to provide distance, midrange, and near vision for pseudophakic patients.
This normal condition is known as presbyopia and develops in most people in between 40 and 60 years of age.
It is first noticeable when it becomes difficult to read items close to you, often requiring reading glasses, bifocals, or trifocals.
If the patient's pupils do not chemically dilate adequately, the doctor will be positioning the haptics around a blind corner, but if the patient's pupils naturally dilate too large, the Crystalens may induced glare in low light environments.
It is possible that a posterior capsule opacification may occur, but a quick laser procedure usually takes care of this problem.
Before this policy change, Medicare's restrictions made it nearly impossible for a patient to acquire a Crystalens IOL. It takes time for your brain and eye muscles to become accustomed to the new possibilities afforded with the Crystalens.
Now the patient may elect to pay the additional fees for the doctor, facility, and lens. Although accommodation may be immediate, expect the changes to be slow with improvement in real function over the first year.
It does not change from distance to near vision, and reading glasses or monovision are required for the patient to be able to see items at all distances.
The purpose of the Crystalens is to provide cataract and RLE patients with the ability to accommodate.

Crystalens is sometimes misspelled as Crysta Lens, Crystal Lens, Crystal-Lens, or Crysta-Lens.
Accommodation with a Crystalens is the same as accommodation with a natural lens.
