EVO ICL™ * Fiscal Year 2020; remaining 13% of sales mix is “Other Products” including aphakic IOLs for cataract surgery and lens delivery systems. **The ICL is a “Phakic” lens that is implanted into the eye without removing the eye's natural crystalline lens. In cataract surgery or refractive lens exchange (RLE) the natural crystalline lens of the patient is removed. “Aphakic” procedures require removal of a person’s natural crystalline lens such as during cataract surgery. An ICL (Implantable Collamer® Lens) is a single-piece foldable phakic** intraocular lens (IOL) made of STAAR’s proprietary Collamer material and implanted into the posterior chamber

EVO ICL™ Technology A Closer Look The EVO lens is implanted in the posterior chamber of the eye. It is positioned behind the iris and in front of the natural lens The EVO ICL is not visible to other people after implantation 10 ICL™
