Every day, one patient at a time, all of us at Harvard Eye Associates strive to provide the latest proven vision solutions for you and your loved ones. If you are interested in seeing your best, please contact Harvard Eye Associates to evaluate the appropriateness of the Verisyse lens implant for you. Together, we will discuss the benefits, risks and costs.

What Is the Verisyse Phakic Lens Implant?

Verisyse Lens Implant

The Verisyse phakic intraocular lens (IOL), manufactured by AMO (Advanced Medical Optics), is a tiny plastic lens that is surgically implanted inside of your eye between the cornea and the iris, and is used for the correction of moderate to severe nearsightedness (myopia).

This type of lens is called "phakic" because your eye retains its natural lens, whereas "pseudophakic" refers to the removal of the natural lens, such as occurs during cataract surgery. Allowing your natural lens to stay in place retains its ability to "accommodate" or see objects that are both near and far without glasses.

The Verisyse acts as a "helper" lens to reduce refractive error and is an alternative to conventional or wavefront Lasik, All-Laser Lasik, PRK, LASEK, and EpiLASIK for patients with very high myopic (nearsighted-shortsighted) vision. Although the Verisyse phakic IOL is intended to be permanent, the procedure is potentially reversible.


The Verisyse lens can improve your distance vision, with the goal of eliminating glasses and contact lenses. This revolutionary implant procedure gives the eye another focusing lens to provide the same quality and definition as that of a youthful healthy eye. By placing the Verisyse phakic IOL micro lens behind your cornea and on top of your iris, your Harvard Eye eye surgeon alters the configuration of your eye for the correction of moderate to severe nearsightedness. Inserted through a tiny incision and implanted in front of the eye's natural lens, the Verisyse lens works by bending light rays so that they focus on the retina.

The Verisyse lens implant is the first phakic implantable contact lens approved by the FDA. Available in Europe for more than a dozen years, over 150,000 Verisyse lenses have been successfully implanted worldwide. An acrylic implantable contact lens, the Verisyse lens is made of polymethylmethacrylate (PMMA), the same material in many intraocular lens implants used in the eyes for over 50 years and proven biocompatible.

For High Degrees of Nearsightedness

Depending upon the architecture of your eye, the size of the pupil, and the thickness of the cornea, LASIK and PRK can be used to correct up to approximately -10 diopters of nearsightedness. However, for patients with higher degrees of nearsightedness, LASIK and PRK are often are not suitable choices.

Today, for people with -10 to -20 diopters of myopia (nearsightedness), the Harvard Eye team offers this promising new procedure. The Verisyse lens implant has been tested and successfully used on thousands of patients in Europe since 1990. In the United States, clinical studies of the Verisyse lens implant procedure began in 1997 and ended in 2003. During that time, over 1000 lenses were implanted in over 500 patients. In this study, over 84% of subjects achieved 20/40 vision or better without the use of glasses or contact lenses (20/40 vision allows people to legally drive without glasses). The Verisyse Phakic IOL was approved by the Food and Drug Administration in September of 2004 and recognized as one of the most impressive advancements in vision science. The Verisyse lens implant is the first implantable lens especially designed to help people who are too nearsighted for LASIK and PRK.
