Verisyse Phakic Intraocular Lens for Extreme Myopia
Reviewed by Marc Michelson, M.D.
An Intraocular Lens is a microscopic lens that can be placed inside your eye in order to correct certain vision problems or conditions of the eye. The most common type of Intraocular Lens is one that is implanted in your eye when you have the natural lens in your eye removed during cataract surgery. This type of Intraocular Lens is called a "Pseudophakic Intraocular Lens" because it is a replacement for your natural lens. It is placed behind the Iris, or colored part of your eye in an anatomical area called the Posterior Chamber. For patients who are extremely nearsighted and may have contraindications to LASIK, an Intraocular Lens may be implanted in front of the Iris, in an anatomical area called the Anterior Chamber. When an Anterior Chamber Lens is implanted, it is possible to leave the natural crystalline lens intact that allows for uninterrupted focusing from far to near, a process called accommodation. For patients who are extremely nearsighted and who have LASIK contraindications, Verisyse™ may be an effective option for correcting their distance vision and maintaining normal focusing ability and near vision.
How Verisyse Works
The Verisyse™ procedure involves placing the Verisyse™ Phakic IOL behind your cornea and on top of your Iris. This gives your eye additional focusing lens that corrects your nearsightedness, much like have a contact lens placed inside of your eye. Although the Verisyse™ Phakic IOL is intended to be permanent, the procedure is reversible if desired.
The word "Phakic" means that your natural crystalline lens is left in the eye. This is important because your natural lens is responsible for helping your eye adjust between seeing objects that are near and far.
