A Multifocal Lens Implant is a lens that has a different power in the center of the lens and another power in the border of the lens so that vision can be focused for far or near out of the same eye. These different zones of lens power work together to provide the eye with near and distance vision. The lenses are made of plastic or silicone materials and placed permanently in the eye after removal of the eye’s natural lens. Subsequently, a Multifocal Lens can help correct Nearsightedness, Farsightedness, and Presbyopia.
The AcrySof IQ ReSTOR IOL is implanted during cataract surgery to replace the natural lens, which has become clouded by cataracts. This new lens can provide enhanced vision quality and full range of vision, giving patients an increased independence from reading glasses and bifocals.
Our eyes are continuously focusing on objects at different distances. Whether it be watching television, sitting at a computer or driving, our eyes automatically focus on different things at different distances quite quickly. As we age, the ability for our eyes to change focus (or accommodate) weakens, which leads to the need for bifocals and reading glasses. By combining the strengths of apodized diffractive and refractive technologies, the Acrysof IQ ReStor IOL provides quality near, intermediate and distance vision and increased independence for reading glasses and bifocals.
