Wonder how LASIK (laser eye surgery) measures up again the new and upcoming Visian ICL (implantable collamer lens) in the treatment of nearsightedness? Find out in their ultimate showdown LASIK vs. VISIAN ICL. LASIK is the most commonly performed vision correction technology used to treat mild, to moderate forms of nearsightedness, farsightedness, and astigmatism. The term LASIK is short for “laser-assisted in situ keratomileusis.” Visian ICLs (Implantable Collamer Lenses)are the newest in the line of revolutionary vision correction technology used to treat mild, moderate, and severe nearsightedness. It’s a small, soft, and flexible gel lens made of a biocompatible material termed “collamer” that is surgically placed in the eye on top of the crystalline lens to treat nearsightedness.
