Multi-focal Implant
The most common treatment today for cataracts is to remove the cloudy natural lens and replace it with an intraocular lens (IOL). The IOL can be monofocal or mutifocal. The monofocal type of lens is usually set for distance. With this lens, if there is no astigmatism, distance vision can be quite good without glasses and glasses would only be required for reading.
The ReZoomä multifocal IOL is designed to provide good far vision as well as intermediate and near vision. When this lens is used, glasses are needed much less frequently. This lens is ideal for the patient who does not want to depend on glasses after surgery.[www.amo-inc.com/site/products/rezoom.asp]
The main disadvantage of this lens is the presence of halos or glare around bright lights. This varies from person to person and in most cases is more noticeable immediately after surgery and diminishes after the first few months.
After having the ReZoomä lens inserted, most people report they can conduct their daily activities without depending on glasses, although you might prefer to use glasses for prolonged reading, to read small type, or to drive at night.
ReZoomä Multifocal IOL Facts at a Glance
Q: Will I still need to wear glasses if my surgeon recommends a ReZoom Multifocal lens?
A: The results will vary depending upon your vision, lifestyle and the anatomy of your eyes. Most people find that they need glasses to read small type or drive at night. Most people, however, can go to the store or conduct many of their day’s activities without depending on glasses. In the cases studied, 92% of those who received the technology in ReZoom Multifocal lenses “never” or only “occasionally” needed to wear glasses.
Q: How is the ReZoom IOL different from traditional single-vision intraocular lenses?
A: The ReZoom IOL is a multifocal intraocular lens. Unlike traditional single-vision lens implants, the ReZoom lens provides quality vision both at a distance and up close. Traditional single-vision lenses usually provide good vision only at a distance with limited ability to see objects that are near without glasses.
Q: How doe the ReZoom Multifocal lens replace the cataract?
The natural lens inside the eye is gently removed through a small micro-incision in the periphery of your eye’s cornea. The cataract-impaired lens is then removed through this incision and the lens implant is inserted in its place to permanently replace it. The procedure usually takes about 15 minutes and vision is usually improved immediately.
Q: How long after surgery until I see my best?
A: Like most procedures, this depends upon the overall health of your eye. For most people, vision is noticeably better immediately and continues to improve during the first few weeks after the procedure.
Q: Does the ReZoom Multifocal lens require an adjustment period?
A: Yes. For most people there is a period of weeks when your brain is learning to “see” up close and at a distance with the new lens. This adjustment period is usually complete within 6 to 12 weeks. Also, like all multifocal lenses, some people report halos or glare around lights. Again, for most people this diminishes over time. For some, it becomes less troublesome but never completely goes away. Most people report that the ability to see near and far outweighs any visual side-effects associated with the lens.
Q: Are there any risks of having the ReZoom Multifocal lens procedure?
A: Yes. With any surgical procedure there are risks. The biggest risk with any cataract procedure is infection. Less than one percent of patients having a lens implant procedure ever get an infection and most are treated successfully with medications. Infections, however, can cause a severe or total loss of vision.
