Life without glasses or bifocals is something most people experienced when they were young. Tenafly Eye Associates is able to give patients choices after Cataract surgery, choices that affect their vision outcomes and possibly freedom from glasses.
During cataract surgery an intraocular lens (IOL) is inserted to replace the natural lens that was removed during cataract surgery. The lens power is determined based upon a series of pre-operative tests. We are able to give patients advice about their options for IOL choice once the testing is complete.
AcrySof® ReSTOR® IOL
The ReSTOR® lens is a multifocal lens implant that is designed to replace the natural lens of the eye after cataract surgery. Comprised of a flexible plastic material, the ReSTOR® lens has a patented design that allows it to focus light on the retina for clear vision at near, far, and intermediate distances. The benefit for cataract surgery patients is a high level of spectacle freedom. Alcon has patented the application of apodization technology to an IOL, making the AcrySof® ReSTOR® lens the first apodized diffractive IOL.
How Does ReSTOR Work?
As we perform daily activities such as reading the newspaper, watching TV or working on the computer, our eyes are constantly changing focus through a process known as “accommodation”. This task is performed by the lens of the eye, which changes shape, or accommodates, to allow the eye to focus at different distances. However, as we age our lens loses the ability to change shape and thus our accommodating ability diminishes, causing us to become more dependent on bifocals or reading glasses. The AcrySof® ReSTOR® IOL by Alcon is a foldable IOL lens that was designed to overcome this dependence, helping correct for the condition known as presbyopia.
Toric IOLs for Astigmatism
If you have been told that you have developing cataracts and you also have astigmatism, new premium lens implant options are available to help minimize your need for glasses after surgery. If you are unsure if have astigmatism please check with your eye doctor.
Astigmatism is a refractive error where people are unable to see objects clearly from a distance or up close. Astigmatism is asymmetric steepening of the cornea or natural lens causes light to be focused unevenly. Astigmatism may occur in varying degrees in each eye and can accompany myopia or hyperopia. For individuals with uncorrected astigmatism, images may look blurry or shadowed.
Toric Lens Implants are a unique type of lens implant that are used to correct astigmatism. A toric lens implant is NOT the only method of astigmatism correction so consult a doctor about the current possibilities. Asymmetric steepening of the cornea or natural lens causes light to be focused unevenly, which is the main optical problem in astigmatism. To individuals with uncorrected astigmatism, images may look blurry or shadowed. Astigmatism can accompany any form of refractive error and is very common. Astigmatism can be corrected with glasses, contact lenses, corneal relaxing incisions, laser vision correction, and special implant lenses. If a cataract patient has astigmatism and has aspirations to be glasses free after surgery the Toric lens implant is a good option. Toric lens implants are NOT a correction option for presbyopia. The ACRYSOF® Toric lens implant is a popular choice for this type of lens.
