EVO ICL is a trademark acronym for Implantable Collamer Lens. EVO ICL’s are advanced technology lenses that can correct low and high nearsightedness and astigmatism. This device is similar to a contact lens but it is placed inside the eye, not on the eye, so it provides constant vision correction.EVO ICL was approved by the FDA in 2005, and worldwide prior to that. Unlike laser vision correction, EVO ICLs are reversible, can correct low to very high nearsightedness (myopia) with or without astigmatism, and do not affect the corneal surface.
