The Verisyse™ Phakic IOL is used to treat moderate to severe nearsightedness. With over 18 years of use and 150,000 procedures performed worldwide, results show that the Verisyse™ design is safe and effective for very nearsighted people in New York and Manhattan who are not candidates for Custom LASIK and do not like thick glasses or wearing contact lenses.

How the Verisyse™ lens works:

To understand how Verisyse™ works, you must first 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.

The Verisyse™ Phakic IOL is placed behind your cornea in the anterior chamber of the eye and on top of your iris. This provides your eye with another focusing lens that can give high-quality, high-definition vision like a normal eye. Although the Verisyse™ Phakic IOL is intended to be permanent, the procedure is reversible if needed.

This procedure entails leaving your natural crystalline lens in the eye. This is important because your natural lens plays an important role in focusing to see objects that are near.

Good candidates for the Verisyse™ Phakic IOL in New York and Manhattan:

  • At least 21 years old
  • Have healthy eyes with no eye disease, iris or corneal abnormality
  • Nearsightedness that can be corrected with lenses between -5 to -20 diopters with up to 2.5 diopters of astigmatism
  • Stable refraction, as determined by Dr. Bonanni (this test determines that your nearsightedness has not changed more than 0.50 diopters for six months prior to surgery)
