AcrySof IQ ReSTOR Multifocal Lens Implant

The AcrySof^® IQ ReSTOR^® IOL Intraocular lens made by Alcon Laboratories (Ft.Worth, TX)  is an artificial lens that is implanted in the eye during cataract or refractive surgery to replace the eye's natural lens that has become cloudy or opaque.  It is a unique technological innovation that can provide enhanced image quality and a full range of vision - near, far and intermediate - for increased independence from reading glasses or bifocals. It is intended for patients who are interested in decreasing or even eliminating their dependency on glasses and contact lenses for both near and far vision. 

How AcrySof ReStor Works

The AcrySof ReStor lens is compromised of 2 regions.  The central 3.6 mm optical zone is compromised of the patented apodized* diffractive optics to provide a range of vision from near to mid-range to distance activities.  This area is formed by 12 concentric rings of various step heights (all smaller than a strand of human hair) that deliver light energy to the back of the eye by distributing the appropriate amount of light to near and distance focal points, regardless of the lighting situation.  The second region or zone is outside of these concentric rings and is considered the refractive zone. This area directs light to a distance focal point and is dedicated to achieving clear distance vision. This unique lens technology is specially designed to distribute light in response to the size of your pupil at any given moment, distributing the appropriate amount of light to near and distant focal points.  It is convex on both sides and is made of a soft acrylic plastic.  Aspheric optics help to counter act the spherical aberrations* of the cornea.  It also has a built in UV blocker* to protect the eye from harmful UV rays.  It is folded and inserted into the eye through a small incision about 1/8 of an inch.  Once inside the eye, it gently unfolds into position.  Up to 80% of patients who use the ReSTOR^® lens don't need to rely on glasses or contact lenses after surgery.

New and Improved ReSTOR lens

Although there have been previous versions of the AcrySof^® IQ ReSTOR^® IOL the +3.0 D add power is the best choice for true performance at all distances.  It provides improved intermediate vision over the original AcrySof® IQ ReSTOR® IOL +4.0 D, with similar near and distance visual acuity.

Disadvantages of the Acrysof ReSTOR                                                                                      

Less-than-crisp distance vision, possible ghosting or "smeared" vision, and impaired intermediate (computer vision range) are possible outcomes of the AcrySof ReStor multifocal IOL.  Again, many patients adapt to the multifocal designs, but there is always a possibility that adaptation will not occur.  As with all multifocal IOLs, impaired night vision due to glare, halos, starbursts (which may be permanent) could occur.

These are considered premium so the additional costs not covered by insurance companies have to be paid by the patient.
