The Implantable Collamer Lens (ICL) for nearsightedness and astigmatism is a refractive lens also known as a phakic IOL. “Phakic” meaning that the natural lens of the eye is in place, and “IOL” meaning intraocular lens, or a lens inside the eye. The EVO ICL is a posterior chamber implant that is introduced through a small incision in the eye and is placed behind the iris (the colored part of the eye), and in front of the natural crystalline lens in order to improve your nearsightedness and astigmatism.

The EVO ICL Lens (EVO) is intended for the correction of moderate to high nearsightedness. EVO ICL and EVO TICL surgery is intended to safely and effectively correct nearsightedness between -3.0 D to -15.0 D, the reduction in nearsightedness up to -20.0 D and treatment of astigmatism from 1.0 D to 4.0 D. If you have nearsightedness within these ranges, EVO ICL surgery may improve your distance vision without eyeglasses or contact lenses. Because the EVO ICL corrects for distance vision, it does not eliminate the need for reading glasses, you may require them at some point, even if you have never worn them before.

EVO ICL represents an alternative to other refractive surgeries including laser assisted in situ keratomileusis (LASIK), photorefractive keratectomy (PRK), incisional surgeries, or other means to correct myopia such as contact lenses and eyeglasses.

Patients who are pregnant and nursing and patients with a narrow angle in the front chamber of their eye, because in this case the space for the EVO ICL lens would be too small. The patient education booklet provides an additional list of conditions that should be taken into consideration when making a decision about the EVO ICL procedure.

The key benefit of EVO ICL surgery is the permanent correction or reduction of your nearsightedness and treatment of astigmatism allowing you to see clearly at long distances without eyeglasses or contact lenses to reduce your dependence upon them. In addition to the improvement of your uncorrected vision (vision without eyeglasses or contact lenses), your best corrected vision (best vision with contact lenses/eye glasses) may be improved.
