Prior to development of IOLs, cataract patients were forced to wear thick glasses or contact lenses after surgery; they were essentially blind without their glasses. However there has been remarkable improvement in the designs of these IOLs over the years. Currently, most IOLs used in phacoemulsification are made of either silicone or acrylic. These materials make the IOLs pliable. Hence they can be folded or rolled to be placed into the eye.
In addition, there is also an array of IOLs ranging from "multifocal" to "wavefront", "yellow", "toric" and many more. The new "multifocal" and accomodating IOLs offer the possibility of seeing well at more than one distance and solving more vision problems than ever. Earlier designs had problems with glare but the current ones semms to work much better and are popular.
