When light enters the eye, it first travels through the cornea. The cornea is normally spherical, and light enters in one direction. In an astigmatic cornea, there are flat and steep areas, causing the light to be misdirected in the eye. Toric IOLs are designed to reduce or neutralize corneal astigmatism and significantly improve uncorrected vision. Each lens is specially selected to correct your personal astigmatism. In some cases, a toric IOL can reduce your dependency on glasses or contact lenses.
The muscles in the eye flex and relax to provide us with accomodation. This abilitiy is gradually lost as we age, and the lens becomes less flexible. Working like a natural lens, the accommodating IOL has a hinged design to allows the part of the lens you see through to adjust and move to focus over a broad range of distances. This is the only lens that provides a single focal point from far to near. The crystalens HD™ IOL is the only FDA approved accommodating intraocular lens.
The ReZoom™ lens is a multifocal lens designed with 5 multifocal rings or "zones" to provide better vision at a variety distances, and in various lighting conditions. An FDA study shows that 92% of all people receiving the lens technology found in ReZoom™ Multifocal Lens never or only occasionally need to wear glasses after the procedure.
The ReSTOR™ lens has a central region called an optic. The optic consists of blended circles which work together through a unique process called apodization. During this process, light is focused within the eye to accommodate both near and far objects, thereby enhancing near, intermediate, and distant vision.
