Phakic IOLs & Visian Glossary: Phakic Intra-Ocular Lenses (IOLs) such as the Visian Implantable Contact Lens (ICL) and the Verisyse (formerly the Artisan lens) are used inside the eye to correct large amounts of nearsightedness. This is an option we offer patients at Stahl Vision here in Dayton Ohio that are too nearsighted for LASIK surgery.
Visian ICL™ receives final approval from the United States Food and Drug Administration
The STAAR Visian ICL is a posterior chamber phakic intraocular lenses. Made of Collamer, STAAR’s proprietary collagen copolymer, the lens rests behind the iris in the ciliary sulcus. This unique material contains a small amount of collagen, which provides excellent biocompatibility and superior optical capability. The lens is gently folded and injected into the anterior chamber through a 3.0mm, temporal, clear corneal incision. The ICL is then carefully positioned by manipulating the footplates of the lens posterior to the iris plane and into the sulcus. The final position of the lens provides a perfect cosmetic appearance, a safe distance from the corneal endothelium and crystalline lens, and an extremely stable refractive outcome.The Visian ICL™ also provides excellent quality of vision. In a comparison of induced aberrations, ten Implantable Contact Lens patients and ten LASIK patients with a range of myopia from –8.0 to –10.0D were evaluated using wavefront analysis at least six months postoperatively.1 The results of these measurements of spherical and coma aberrations demonstrate a favorable advantage of the Visian ICL over LASIK for these high levels of myopia.
There have been approximately 50,000 ICL’s sold world-wide. Extensive development has been undertaken to deliver the most recent version of the ICL - V4. Version 4 of the ICL is optimally vaulted to produce consistent clearance from the crystalline lens; an improvement over earlier versions of the lens. This is important to minimize the incidence of developing a cataract after implantation with the Starr Visian ICL. The Visian ICL™ is approved for use in myopes between -3.0 to -20.0 diopters. FDA labeling recommends patients be 21 - 45 years of age with an anterior chamber depth (ACD) 3.00mm or greater, and a stable refractive history within 0.5 diopter for 1 year prior to implantation. In practical use however, there is a concern about any lens inside the eye causing more rapid development of cataracts if left in the eye over a long enough period of time. Thus the best candidates are patients between 40 and 60 years of age who have become intolerant to contacts lenses. Everyone develops a cataract eventually as we get older, it is a natural part of the aging process. Stahl Vision- building better vision, one patient at a time... |

The Visian myopic implantable contact lens (ICL) is used in the correction
of nearsightedness. Unlike laser refractive surgery, the ICL is removable
and does not permanently alter the shape or structures of the eye.
Phakic IOLs such as the Visian are a good option for patients with high
amounts of nearsightedness or those with thin corneas in whom LASIK is not
a good option.
