What is Crystalens Aspheric Optic?

Dependence upon corrective lenses to improve your vision becomes tiresome. Some patients opt for a more permanent solution that can correct both cataracts and presbyopia at the same time: the Crystalens Aspheric Optic lens procedure. Here is a quick rundown of the procedure, its benefits, side effects, and the downtime you can expect for recovery.

What Crystalens Aspheric Optic Means

Crystalens Aspheric Optic is an intraocular lens (IOL) implant procedure that uses the eye’s inner focusing muscles to flex an accommodating lens. This allows the lens to adapt and focus at varying distances in a more natural way.

The Procedure

This type of IOL implant takes about an hour and is an outpatient procedure. It includes the following steps:

  • numbing and relaxation of the eye
  • making a tiny cut through the cornea to get to the lens of your eye
  • removing the existing lens
  • implanting the new lens
  • healing without stitches

Once the procedure is finished, you will be free to go home, although you will need someone else to drive.


Crystalens Aspheric Optic provides a number of key benefits over other types of IOL implants. Here are a notable few.

  • It provides for excellent quality of vision over a wide natural range.
  • Near, intermediate, and distant vision outcomes can be sustained for up to seven years.
  • Spherical aberration (loss of image definition) can be reduced to zero.
  • It does not compromise field of depth.


When considering all forms of surgical or non-surgical eye treatment options, it is best to understand the possible negative side effects. The potential risks related to this procedure include shifting or improper lens placement, as well as corneal clouding. There is also no long-term data concerning effectiveness and longevity beyond 7 years.

With all forms of eye surgery, there is the risk of infection, vision loss, and a detached retina, although these are rare.

Recovery Time

Recovery times vary from one patient to the next, but most common visual tasks can be performed immediately after surgery. However, there are special instructions for some tasks along with recovery orders.

If you are tired of your reliance on corrective lenses for proper vision, and/or suffer from cataracts and presbyopia, the Crystalens Aspheric Optic lens might be the solution you are looking for.
