Cataract patients now have options for more independence from glasses at both near and far distances after cataract surgery. Previously, patients suffering from cataracts had only a standard single vision lens implant option after surgery. Now with advancements in intraocular lens (IOL) technology, a number of premium IOLs are now available, including accommodating, multifocal and toric lens implants. Your doctor will help you decide which lens implant is best for you based on the unique characteristics of your eye and your lifestyle needs.
Standard Single Vision IOLs
Traditional monofocal IOLs have a fixed focal point that is usually set for distance vision, so reading glasses are usually necessary for good near vision. In some cases, patients may choose to focus the lens for near tasks, such as reading. In these cases, glasses or contact lenses would be necessary to see clearly at distance, such as for driving. Standard single vision lenses do not correct astigmatism, and any remaining astigmatism after cataract surgery may cause blurring of vision at all distances without glasses. If you are having cataract surgery, these lenses are covered with the expense of the surgery.
Many patients suffer from the common eye condition known as astigmatism. Often this astigmatism can lead to blurred or impaired vision, as a result of the eye having an irregular shape. A normal eye has a round, spherical shape, whereas an eye with astigmatism has a longer, more oval shape.
We are pleased to offer the new Acrysof Toric IOL for correction of astigmatism at the time of cataract surgery. These lenses are designed to help patients with astigmatism achieve better vision than they would with a standard single vision IOL. Toric IOLs neutralize or compensate for naturally occurring astigmatism in the cornea, thereby reducing the need for glasses and improving quality of vision. They do not provide BOTH near and distance vision simultaneously.
ReSTOR Multifocal IOL
A revolutionary breakthrough in lens technology, the ReSTOR multifocal IOL provides a full range of vision – near, far and everything in between – thus reducing or eliminating the need for glasses after surgery. No matter what we are doing, our eyes are continuously focusing on objects at different distances. As we age, our eyes gradually lose the ability to change focus, or accommodate, which leads to the need for reading glasses or bifocals.
ReSTOR multifocal IOL gives patients a clinically-proven way of leaving glasses behind, because it is designed with apodized diffractive technology. This patented, FDA approved design improves image quality while minimizing visual disturbances. The net result is an enhanced range of quality vision. Clinical studies showed a high rate of patient satisfaction, with over 94% of patients stating that they would have this lens implanted again.
TECNIS Multifocal IOL
Designed to give patients back their youthful vision, the TECNIS multifocal lens provides patients with high-quality vision at any distance, and at any lighting condition – even in low light. This offers patients an excellent chance of becoming spectacle independent after cataract surgery. Approved by the FDA in 2009, this lens uses diffractive rings on its inner surface to focus the light from objects in our vision at varying distances. This allows for a smooth transition of focus between distant, intermediate and near targets.
The clinical studies supporting the FDA approval of TECNIS mutifocal IOL indicate that:
