Verisyse Phakic IOL

The Verisyse™ Phakic intraocular lens (IOL) is used to treat moderate to severe myopia, also known as nearsightedness. With over 18 years of use and 150,000 procedures performed worldwide, Verisyse™ lens design is safe and effective for very nearsighted people who are tired of thick glasses and are not candidates for custom LASIK procedures.

How Verisyse™ Works

The procedure involves placing the Verisyse™ lens behind your cornea and on top of your iris. This gives your eye another focusing lens that provides high-quality, high-definition vision like a normal eye. Although this lens 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 plays an important role in helping your eye adjust between seeing objects that are near and far.

The Verisyse™ Procedure

Implanting the Verisyse™ lens is an outpatient procedure that takes approximately 15 to 30 minutes. Usually, one eye is treated at a time.

  • Drops will be placed in your eyes in order to reduce the pupil size.
  • For better access to your eye, the physician will use an instrument to comfortably hold your eyelids open during the procedure.
  • A local anesthetic is given to numb the eye, so the procedure is virtually painless.
  • A small incision is made in the cornea for the Verisyse lens to be placed in the space between the iris and the cornea.
  • The lens is centered in front of the pupil (the black part in the center of your eye), and is gently attached to the iris (the colored part of your eye) to hold the lens in place.
  • The small incision is closed with microscopic stitches that dissolve over time.
  • A temporary shield will be placed over your eye to protect it during the time just after the procedure.


Will I be able to see or feel the Verisyse™ Phakic IOL in my eye?
Once the Verisyse™ Phakic IOL is placed inside your eye, it is virtually undetectable; however, you and others may be able to see the lens in your eye if you look very closely. Because the Verisyse™ Phakic IOL is placed inside your eye, you will not be able to feel it.

Is Verisyse™ safe?
Yes. The Verisyse™ Phakic IOL is made from polymethyl methacrylate (PMMA) -- an extremely well proven biocompatible material that has been widely used in and on eyes for over 50 years.

Can I see well near and at a distance with the Verisyse™ Phakic IOL?
Most people who have the Verisyse™ procedure see well atnear and at a distance because their natural lens is left in place. This lens (the crystalline lens) naturally adjusts to focus on near and distant objects. As you age, this natural lens function may diminish and you may need reading glasses to see objects that are near.

Can I go swimming with the Verisyse™ Phakic IOL in my eye?
You can swim and participate in virtually any other activity with the Verisyse™ Phakic IOL because unlike contact lenses, the Verisyse™ Phakic IOL is implanted in the eye, in front of the crystalline lens. Therefore, it is not affected by external elements such as water.

Is the Verisyse™ Phakic IOL affected by elements like rain or steam?
The Verisyse™ Phakic IOL is not affected by external elements like rain or steam because it is implanted behind the cornea of your eye.

How long does the Verisyse™ Phakic IOL last?
Clinical evaluations have proven that PMMA can remain in the eye for decades without changing its properties or losing stability; however, the procedure is completely reversible. If, in the future, your surgeon determines that there is a better procedure, the Verisyse™ Phakic IOL can be surgically removed at any time. Only your doctor can determine if this measure may be necessary.
