Intraocular Lens Implants (IOL) for Vision Correction After Cataract Surgery

Reviewed by:

Jason Jacobs, MD & Paul Koch, MD

Intraocular Lenses (IOL) have been used to correct vision after Cataract Surgery for many years. IOLs are permanent artificial plastic lenses that are used to replace the cloudy Crystalline Lens of your eye that is removed during Cataract Surgery. Early Intraocular Lenses were manufactured from a rigid plastic that required implantation through a moderate sized incision that required stitches or sutures. Today's Intraocular Lenses are manufactured from flexible acrylic materials, silicone or proprietary co-polymers that are actually foldable and can be inserted through the same very tiny incision used to remove the Cataract. Typically the Lens Implant can placed in the eye in a "folded up" configuration, which unfolds into its correct position after just a few seconds after implantation.  Up until recently, choosing the type of Lens Implant to correct your vision after Cataract Surgery was left entirely to the Cataract Surgeon. Today, there are many types of Intraocular Lens Implants (IOL) that your surgeon can use in order to provide you with the best results to match your lifestyle.

These different types of Lens Implants include Monofocal Lens Implants  which are the most basic type of lens implant and only correct distance vision and not arms length or close reading vision, Aspheric Lens Implants which offer a higher quality of distance vision but still do not correct arms len or close reading vision, Toric Lens Implants for those patients with astigmatism and Near Vision Presbyopia Correcting Lens Implants such as the Crystalens® Lens Implant, the ReSTOR® Lens Implant and the ReZoom™ Lens Implant which correct distance vision, as well as arms length vision and close reading vision for most patients. In addition, for those patient who may have already had Cataract Surgery and who wish to decrease their dependence on eyeglasses for reading, reading glasses or bifocals, it may be possible for your surgeon to implant a Piggyback Lens Implant to help you achieve your personal vision correction goals.

Based on the results of your Cataract Examination, your lifestyle and your desire to conduct your daily activities without being dependent on eyeglasses, contact lenses, bifocals or reading glasses your surgeon and their staff will guide you in choosing the best Lens Implant for your individual needs.
