Visial Implantable Collamer Lens (Visian ICL)
The Visian ICL is designed for the correction of moderate to high nearsightedness. Visian ICL surgery is intended to safely and effectively correct nearsightedness between -3 diopters to -15 diopters and partially correct nearsightedness to up to -20 diopters in eyes with up to 2.5 diopters of astigmatism. It is not intended to correct any astigmatism you may or may not have. If you have nearsightedness within these ranges, Visian ICL surgery may improve your distance vision without eyeglasses or contact lenses. Because the Visian 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.
