Implantable Collamer Lenses or Implantable Contact Lenses ICL frequently asked questions.
The Visian ICL is a very effective implantable collamer lens (sometimes called an implantable contact lens) for many people who have moderate to severe myopia, or nearsightedness. Until now, however, people with steep astigmatism were not candidates for ICL, or for many other procedures. Visian Toric ICL was developed specifically for those patients in mind. It treats myopia as well as astigmatism, and it has also been effective in managing an eye disease called kerataconus.
