Crystalens Accommodative Lenses

What is Crystalens?

Drs. Alvi or Quraishi provides patients with the Crystalens™ procedure. Crystalens is an accommodating intraocular lens used to treat both cataracts and presbyopia, the progressive inability to focus on near objects, commonly developed with age. Crystalens works by recreating accommodation similar to your eye’s natural lens. It uses the eye muscle to flex in order to focus on objects at all distances. This design allows the optic to move back and forth as you constantly change focus on images around you.

The Crystalens Procedure

The Crystalens procedure is an outpatient surgery, typically takes about 15-20 minutes, and is painless. Drs. Alvi or Quraishi will begin by numbing the eye with drops and sealing the cornea. The natural lens is then gently removed, and the Crystalens implanted. Normal activity can be resumed almost immediately after surgery, with a total recover time of only 2-3 days.

Benefits of Crystalens:


  • Crystalens is the first and only FDA-approved accommodating intraocular lens.
  • Over 200,000 patients worldwide have successfully been implanted with Crystalens, and the number continues to grow daily.


  • Over 88% of patients implanted with a Crystalens could see better at all distances, compared with 35.9% of patients achieving the same results from a standard intraocular lens.
  • Postoperatively, most Crystalens patients are able to see close-up without glasses, meaning reading the newspaper or seeing the keyboard will be easier than ever.
  • Most patients also report excellent improved distance vision, ranging from 20/40 to 20/20, meaning driving and watching TV will have newfound ease.
  • Most patients report having the same improved vision 7 years after their Crystalens implantation.


  • Only Crystalens treats both presbyopia and cataracts, while improving overall vision and eliminating or reducing your dependency on glasses and contacts.
  • Unlike multifocal lenses, Crystalens directs all available light received by the eye to a single focal point, just like a natural lens.
  • Patients with Crystalens do not need to neuroadapt to viewing multiple images as they would with a normal multifocal lens, because only Crystalens produces a single image consistent with normal vision.

FAQ about Crystalens:

Is Crystalens a permanent solution to my cataract problems?

The Crystalens surgery is permanent and the well-tested, durable design has allowed the flexing ability of the lenses to remain completely unchanged in patients for years.

Does Insurance or Medicare generally cover Crystalens?

Though insurance coverage varies, most private insurance and Medicare will cover the procedure, and may even provide an additional sum for the artificial lens implants.

What are the side effects of Crystalens?

Crystalens has the same risks as surgically implanting any standard intraocular lens. Glare, halos, and other visual disturbances may occur under certain lighting conditions, particularly at night. Our doctors can help you determine if Crystalens is right for you.
