In a cataract surgery, the cloudy natural lens of the eye is removed and replaced with an intraocular lens. In the past, patients only have one option: the monofocal IOL. This provides good distance vision, but for activities that require near vision such as reading, patients must continue to wear prescription eyeglasses. Now, with the AcrySof IQ ReSTOR multifocal intraocular lens, you can reduce your dependency on eyeglasses and restore both near and distance vision!
What is the ReSTOR Multifocal Intraocular Lens?
Our eyes change focus quite quickly. One moment you are watching television, the next you’re reading a text message. As we age, our eyes gradually lose this ability; hence the need for eyeglasses or bifocals.
The AcrySof IQ ReSTOR is a type of intraocular lens designed to replace natural lens that has become clouded by cataracts as well as correct presbyopia. It is not like the traditional monofocal IOL that allows you to see things only in the distance. The unique engineering of the ReSTOR multifocal intraocular lens allows for multiple points of focus so you can see things at different distances.
The ReSTOR lens consists of a series of concentric rings. Some rings are for distance vision; some rings are for near vision. The rings decrease in height from the center towards the periphery of the lens surface, a principle is known as apodization. The varying height design helps decrease night glares and halos and makes ReSTOR lens the best multifocal lens for night driving!
Am I a candidate?
Anyone over the age of 40 is a potential candidate for ReSTOR IOL implantation, as well as people who have:
- Begun to develop cataracts
- Near vision problems caused by hyperopia
- Severe levels of myopia
Certain health conditions may prevent you from having the procedure. Your eye doctor will determine if you are a good candidate during the examination.
The ReSTOR lens is FDA-approved both for cataract surgery as well as refractive lens exchange. The procedure is basically the same for both. First, the natural lens is removed, then replaced with ReSTOR lens. The difference is that in a cataract surgery, the lens is clouded. In refractive lens exchange, the lens is presbyopic but clear.
Both cataract surgery with IOL implantation and refractive lens exchange take only a few minutes, and the visual results are immediate. Most patients are able to return to normal activities within 24 to 48 hours after surgery.
