The Visian ICL provides vision correction that goes beyond LASIK. It helps you enjoy sharper, clearer, and more vivid vision, with greater depth and dimension. Good candidates for the Visian ICL include patients who: Are nearsighted with or without astigmatism* or farsighted*, including those with mild, moderate, and severe myopia (as low as -3D to as high as -20D prescription) with minor or no occurrence of astigmatism. Have not had a change in their eyeglass prescription of more than 0.5D in a year. Have dry eyes, severe myopia, or a thin cornea (non-LASIK candidate). The implantation procedure for the Visian ICL involves a procedure similar to that of cataract surgery. The main difference is that, unlike cataract surgery, the Visian ICL procedure does not require the removal of the eye’s crystalline lens. And unlike the LASIK or PRK refractive procedures, the Visian ICL procedure does not involve the removal of sensitive eye tissue.
