http://www.edow.com/images/img-staar.jpgThis STAAR Visian Implantable Contact Lens™ (ICL) is another type of phakic intraocular lens used to treat moderate to severe myopia. There have been approximately 40,000 ICLs implanted world-wide, and the lens recently received FDA approval for use in the United States. The lens is made of "collamer," a unique material that contains a small amount of collagen, which provides excellent biocompatibility and superior optical capability.
Patients who are suited for this lens usually have a high refractive correction, thin corneas, or a preference for non-laser vision correction. Some patients prefer the STAAR® ICL procedure compared to the laser procedure because it is reversible. In contrast to the LASIK procedure where tissue is permanently removed, the STAAR® lens implant can be removed, if needed. In addition some studies have shown that at high levels of correction (-8.0D and above), there may be less higher-order aberrations after the lens implantation when compared to rather than LASIK, which may translate in clearer vision.
The Procedure
During the procedure,with the eye under a local or topical anesthetic, the surgeon will create an incision in the eye. The implantable contact lens (ICL) is then gently folded and injected into the anterior chamber through a 3.0mm, temporal, clear corneal incision. The ICL is then carefully positioned. Following implantation, the lens rests behind the iris surface, vaulted over the natural lens of the eye.
