Multifocal Lens Implants
Cataract surgery is very good at helping people to see better at a distance; for example, you may be able to see the television or to drive without eyeglasses after this surgery. However, reading and doing other up-close work may be harder. Multifocal lens implants can be placed into your eyes to improve up-close images, giving you better vision overall. When you visit us in Brooklyn, our eye surgeon will have a detailed discussion with you about multifocal lens implants.
Who Will Benefit from Multifocal Lens Implants?
If you have cataracts and are planning to have cataract removal surgery, now is the time to consider the potential benefits of multifocal lens implants. Without this type of implant, most people who have their cataracts removed need to purchase bifocals for reading and other up-close work. Multifocal lens implants can be a better option, making eyeglasses completely unnecessary. Otherwise, it is most likely that after having your cataracts removed, you will require some type of vision assistance.
What does a Multifocal Lens Implant Procedure Involve?
There are several FDA-approved implantable multifocal lenses available, including AcrySof IQ ReSTOR, Tecnis Multifocal, and Tecnis Symfony lenses. When you come in for your exam, we’ll discuss all the options to determine which is best for your needs.
Implanted lenses work a bit differently than bifocal eyeglasses. A multifocal lens is specifically designed to provide for distance , near and intermediate vision at the same time. In contrast, bifocals require you to look through different portions of the lens to see clearly at various distances, whether you’re reading a menu, looking at your computer screen, or identifying a neighbor across the street.
Before the implant procedure begins, you will receive sedation and numbing agents, so you will not experience any pain. During the procedure, the surgeon creates a small, nearly invisible, incision in the eye, removes the cataract or crystalline lens and inserts the lens implant. The incision is so tiny that usually no stitches are required.
Although your vision is likely to be blurry for a while after the surgery, you’ll notice some improvement in the first few days. Most people see significant improvement in their vision within a few days to a week. Soon, you’ll find you can see and do things that you had not been able to do for some time because of your compromised vision.
It’s important to talk to our team about your vision, your overall health, and the benefits you hope to gain from multifocal lens implants. When you come in for a consultation with us in Brooklyn, we will discuss multifocal lens implants with you in detail.
Premium Lens Implants
Symfony, the latest advancement in IOL (Intraocular Cataract Lenses) optical technology are the first and only FDA approved presbyopia-correcting Extended Range of Vision lenses.
Unlike traditional multifocal lenses, Symfony targets Presbyopia which is farsightedness caused by the loss of elasticity in the lens due to aging. Recovery from surgery is minimal where patients can return to their usual routine 24 hours after surgery. Symfony patients also reported a low incidence of glares & halos, a common a side effect caused by traditional lens implants.
Symfony Extended Range of Vision IOL is available in both a Non-Toric version and a Toric version for patients with an astigmatism.
Crystalens® – Far, near and everything in-between
Crystalens, manufactured by Bausch & Lomb, gained FDA approval in late 2003. A newer version of the IOL, known as Crystalens HD, was approved by the FDA in June 2008. Crystalens was designed to restore the ability of the eye to focus, or accommodate, which is gradually reduced in patients after the age of 40.
Crystalens implants can give individuals clear reading vision (within 1 to 2 feet), arm’s-length vision (2 to 3 feet), and distance vision without glasses, because the implant actually adjusts its position within the eye as the eye looks from far to near subjects, just like the autofocus mechanism on a camera. Most people with Crystalens implants have clear distance and intermediate vision without any need for glasses. This enables them to drive, watch TV, and use a computer, all without eyeglasses. About 90 percent of people can also read newsprint unaided after receiving Crystalens implants.
ReSTOR® – The Space-Age
AcrySof ReSTOR, manufactured by Alcon, uses apodized diffractive technology — a design that responds to how wide or small the eye’s pupil is — to provide near, intermediate, and distance vision. Clinical studies used to support the March 2005 FDA approval showed that 80 percent of people who received the lens didn’t use glasses for any activities after their cataract surgery.
The ReSTOR lens is a nonmoving lens implant. Alcon’s high-tech manufacturing process creates a gradual blending of focusing power throughout the entire lens surface. With the ReSTOR lens, over 90 percent of people can clearly see distant objects, such as road signs, as well as near objects, such as reading material within 1 to 2 feet, especially in good light. As with all multifocal lenses, a period of adjustment is required for your brain to get used to the lens. The length of the adjustment period depends on several factors, including your age and your vision requirements.
TECNIS®Multifocal IOL – Youthful Vision after Cataracts
The Tecnis Multifocal IOL from Abbott Medical Optics is a diffractive artificial lens with specific zones that provide near, intermediate, and distance vision. Company officials say the lens has a proprietary design to enhance vision at all distances without depending on the size of the pupil as it expands in low light or constricts in bright light. The Tecnis lens is shaped to correct for certain higher-order aberrations, which helps improve the ability to see contrasting objects, particularly at night. AMO reported a 95 percent patient satisfaction rate in clinical trials leading to FDA approval in early 2009
