More Info		Procedures > Refractive Surgery Options > Verisyse   Phakic Implantable Lens   The Verisyse™ Phakic Implantable Lens is a micro lens placed behind your cornea. It is made out of "PMMA," which is the same type of material used safely for the past 50 years in cataract surgery. The word "phakic" means that your natural crystalline lens is left in the eye (not removed as in cataract surgery). This is important because your natural lens helps your eye adjust between seeing objects that are near and far.

With successful use in more than 150,000 procedures world wide, the Verisyse™ design is proven to provide very predictable correction of moderate to severe nearsightedness. During FDA clinical trials, an overwhelming majority of patients (more than 90%) were satisfied with the procedure and would recommend it to a friend.

To understand how Verisyse™ works, you first have to understand how the eye works. There are several structures in your eye needed to convert light into the images you see. When light enters the eye, your cornea and crystalline lens focus it onto the retina, which transforms it into the electrical signals that are sent to your brain. Because the cornea has the greatest focusing power, it’s the cornea’s shape that determines the majority of the eye’s focusing ability.

Through a small incision, your doctor places the Verisyse™ Phakic Implantable Lens behind your cornea. You generally do not feel or see the lens once it is in place, and it can never slip or fall out.
