The Verisyse™ lens, offered by our Virginia area surgeons at Eye Doctors of Washington, is used to treat moderate to severe myopia. With over 18 years of use and 150,000 procedures performed worldwide, results prove that the Verisyse™ design is safe and effective for individuals with severe myopia (nearsightedness) - who are tired of thick glasses and are not candidates for Custom LASIK.
These individuals may not qualify for laser vision correction because they have a high refractive correction, thin corneas, or a preference for non-laser vision correction. In contrast to a laser procedure, where tissue is permanently removed, the Verisyse™ lens can be removed, if needed.
The Procedure
The Verisyse™ lens is comprised of a convex or concave, 5 or 6 mm optic, on an 8.5 mm wide elliptical carrier (Figure 1). Implanting the Verisyse™ lens takes approximately 15 to 30 minutes during which time the surgeon creates an opening in the iris with a laser to assist fluid flow through the chambers of the eye. The eye is then numbed with local anesthesia and tiny incisions are created in the cornea. Using specialized instruments, the Verisyse™ lens is inserted behind the cornea and in front of the iris, giving the eye another focusing lens that provides high-quality, high-definition vision (Figure 2). Following implantation, the Verisyse™ lens rests on the edge of the iris, vaulted over the central iris and pupil, and positioned in front of the natural lens of the eye (Figures 3-5). Once the Verisyse™ lens is in place, the small corneal incision is closed with microscopic stitches and a temporary protective shield is placed over the eye. Patients may return home soon after the procedure is complete.

Comparison of STAAR Visian ICL™ and Verisyse™

Both the Verisyse™ and STAAR Visian ICL™ are safe and effective phakic intraocular lenses. Both provide excellent outcomes as alternatives to laser surgery for the correction of moderate to high myopia. There are some differences between the two lenses in their approach to treating refractive errors.
The reason that the Visian ICL has supplanted the Verisyse lens is two fold:

The Visian lens is foldable as opposed to the ridgid Verisyse lens, allowing for a much smaller incision.
The Visian lens is placed behind the iris making it invisible to the naked eye whereas the Verisyse lens is placed in front of the iris.Overall, however, they are both safe and effective lenses, and your surgeon will work with your individual case to help you select the most appropriate lens for your eye.
