How Phakic Intraocular Lenses Differ from Crystalens
Today’s advanced vision technology offers two excellent options for patients seeking improved vision.
The Verisyse™ Phakic Intraocular Lens
Verisyse is a Phakic Intraocular Lens (IOL) implanted in the eye, either temporarily or permanently, to improve moderate to severe nearsightedness. The term “phakic” refers to an eye that retains its natural crystalline lens. In nearsightedness, the cornea, or front surface of the eye, bends light rays so that the light focuses correctly on the retina. Therefore, the cornea is too steep, focusing light rays in front of the retina and causing blurry vision.
The Verisyse Phakic IOL is implanted behind the cornea, on the iris, for improved focusing of light and, therefore, improved vision. The cornea remains in place and continues to focus between far and near objects. People who wear thick glasses or contact lenses and do not qualify for LASIK are excellent candidates for the Verisyse Phakic IOL.
Verisyse lenses are made from PMMA, a material used successfully in cataract surgery for over fifty years. The implant procedure is performed on an outpatient basis under local anesthesia and takes approximately thirty minutes. The best candidates for the Verisyse Phakic IOL are:
- Over 21
- Have good eye health
- Have stable vision
- Are not pregnant or nursing
Crystalens™ Accommodating Intraocular Lens
Crystalens™ is a multifocal IOL designed specifically for replacement of the eye’s lens after cataract removal. Crystalens is made from a flexible silicone that features a hinged design. This means Crystalens™ can work naturally with the ciliary muscles of the eye so that the eye can “accommodate”, or shift its focus between distant and close objects. With monofocal IOLs, this ability is lost and the patient requires glasses or contact lenses to see clearly at all distances.
Crystalens™ is implanted using nearly identical surgical techniques as for cataract surgery. Success rates are high and millions of people today enjoy improved vision and freedom from corrective eyewear after cataract surgery because of Crystalens.
The best candidates for Crystalens are individuals who are:
- Over age 50 years
- Have cataracts
- Want to restore their full vision range
- Have little to no astigmatism
- Have good eye health
- Have not had previous cataract surgery
