The AcrySof® IQ ReSTOR® intraocular lens (IOL) has revolutionized the field of vision restoration, allowing thousands of cataract sufferers to regain clear, crisp eyesight. For many people who are interested in the ReSTOR® IOL, the bottom line is enough: this extraordinary lens implant allows people to see clearly at near, intermediate, and far distances without the aid of reading glasses or bifocals. Others, however, may be interested in the science behind this breakthrough technology.
The ReSTOR® IOL replaces the natural lens of the eye after it has been removed during cataract surgery. The artificial lens restores a person’s ability to accommodate – that is, to quickly adjust focus within the range of vision. This is an ability that comes naturally to most in their youth; however, with age, it begins to wane. The ReSTOR® IOL returns this ability through its unique apodized diffractive technology.
Apodized diffractive technology?
Admittedly, this is not a common phrase. However, the idea is simple. Diffraction refers to the distribution of light as it is processed through a lens. Apodization refers to a layering of “steps” that lead down from the center of the lens to its edges. These steps allow light to be spread effectively at all distances. Each step accommodates light from a different distance, focusing it on the retina to produce a sharp, vivid image.
Truly, the ReSTOR® IOL presents cataract sufferers with an opportunity that was not available in the past: the opportunity to say goodbye to reading glasses and bifocals and hello to crisp, unaided vision.
