What is the Crystalens?

crystalensThe Crystalens is a revolutionary new breakthrough in vision enhancement. It is the first and only intraocular lens (IOL) replacement that focuses like the eye's natural lens, allowing for continuous vision up close, far away and all distances in between. By using the eye's muscle to move the lens backwards and forwards naturally in response to the brain's desire to see at different distances, the Crystalens enables the eye to focus continuously and seamlessly through a range of distances. Patients experience the same vision they had when they were younger, for most without the inconvenience of corrective lenses.

What makes the Crystalens different from other intraocular lenses?

After the age of 40 people will often start to experience serious trouble reading as the eye’s natural lens starts to harden. This inability to see at close distances or difficulty for the muscles in the eye to auto-focus can be very discouraging. This is known as loss of accommodation, or presbyopia. The Crystalens lens was researched and developed specifically to help correct the aging vision condition and was engineered with a hinge design that allows the optic to move as your focus on an image changes. The Crystalens has the unique ability to focus on objects at varying distances using the eye’s natural muscles.


This means that the Crystalens can provide sharper vision, without corrective lenses, throughout a full range of vision from near to far and everything in between. Standard (single vision) lens implants do not have the ability to provide a full range of vision. Most people who have single vision lens implants MUST wear glasses for middle and near vision. It was shown in the two year clinical trial that supported the FDA approval of the Crystalens that:

  • Significantly more patients implanted with a Crystalens (88%) could see better at all distances than patients implanted with a standard lens (36%).
  • 73.5% of patients who received the Crystalens said they never or almost never wore spectacles.
  • 85% of patients said they didn’t need spectacles at night.

How do I know if I am a good candidate for Crystalens implantation?

The best candidate is the individual who is 45 or older who is dependent on glasses and/or contacts to see near, far and in-between. Your doctor will perform a thorough examination and advise you of a customized treatment plan for effectively correcting your vision. Virtually everyone with good general health is a candidate for implant surgery, but people with chronic infections, uncontrolled diabetes, or other health problems may have to wait until these conditions are under control prior to surgery. People who have had prior corneal refractive surgery are acceptable candidates for Crystalens implantation as long as their eye is in good health. Talk to your doctor. If you have already had cataract surgery, you are not a candidate for the Crystalens procedure.
