The surgical procedure to implant the Visian ICL is simple and painless. As a Visian ICL candidate, your surgeon will prepare your eyes one to two weeks prior to the procedure by using a laser to create two very small openings in the colored part of your eye which lies between the lens and the front chamber of your eye. This allows for the natural passage of fluids between the two areas, thereby avoiding the build up of intraocular pressure following the treatment.
