Verisyse™ is the trade name of a phakic intraocular lens (IOL). The term phakic refers to an eye which still has its natural lens. There are other types of IOLs, such as Crystalens, which require the natural lens to be removed, and they will substitute for it. But a phakic lens is inserted in front of the iris (colored part), to supplement the eye’s refractive ability.
Verisyse is used for moderate to severe nearsightedness (myopia). If you have been told that you are not a good candidate for LASIK, a Verisyse procedure would be another alternative for you.
What is Myopia?
The cornea (clear front part of the eye) bends light entering the eye, and the lens (behind the iris) bends it more. Between them, the cornea and lens should focus that incoming light on the retina to give you clear vision.
But a myopic eye has a steeply curved cornea. It bends light too much, so that by the time that light passes through the lens as well, it has been refracted so much that it focuses in front of the retina. That means the light-sensitive cells in the retina do not receive full image information. What they do receive, they pass on to the brain via the optic nerve, and the brain does its best to interpret the partial information and supply names for you.
You have blurry vision for distant objects but can see clearly up close. That is because close-up objects need the light to be bent more than far objects do. Your eyes are supplying enough refraction for the close-up things but cannot reduce refraction enough to give you clear images of far objects.
How does a Verisyse IOL work compared to LASIK?
In principle it works the same way as a LASIK surgery: it changes the way your eyes refract light. In practice, it takes another route to accomplish this goal.
LASIK vaporizes tiny pieces of corneal tissue to somewhat flatten the corneal curvature, and the new curvature bends light correctly so you have clear vision at all distances.
A Verisyse IOL bends incoming light rays, modifying the refraction already being done by both the cornea and the lens. The end result is correct refraction for distance vision. The eye’s lens will take care of near vision by altering its own curvature, a process called accommodation.
The Verisyse Procedure
It is more like a cataract procedure than LASIK, except that your natural lens will not be removed. It is an outpatient procedure taking between 15 and 30 minutes. Dr. Almallah uses a laser to make one or two tiny perforations at the edge of the iris. These are to allow fluid to move freely between the areas behind and in front of the iris. You will not be able to see them.
Eyedrops are used to reduce the size of your pupils and anesthetic drops will numb the eyes. Dr. Almallah makes a tiny incision to insert the Verisyse IOL in front of your iris. He centers it in front of the pupil and attaches it to the iris for stability. Tiny dissolvable stitches close the incision. He will place a temporary shield over the eye to protect it during your recovery period.
Most people achieve better than 20/20 vision with a Verisyse IOL. Many achieve 20/20, and all are extremely pleased with the results.
