In virtually every instance, at the time of cataract surgery, once the cataractous protein lens is completely removed, an intraocular implant (IOL) is then inserted and centered into the eye. There are two main categories of implants: monofocal implants and multifocal implants. To find out more about monofocal implants, click on the link above.
Multifocal implants are specially designed lenses that allow patients to see at various distances (far and near) without the need for glasses. Not every patient is a candidate for this type of lens. Only a doctor that is specially trained to implant these types of lenses can determine if it is right for you. Currently, there are three brands of multifocal lenses available in the U.S. (ReSTOR, Rezoom, and Crystalens. You and your doctors at the Texas Vision & Laser Center will determine which, if any, is right for you. Please click on the links above to find out more about each of these implants.
Although these multifocal implants work very well in the right type of patient, there are a few considerations every patient must consider before electing this option. First, these implants are not covered by any insurance plan (not even medicare or any medicare supplement), and must be paid for entirely by the patient. Second, in some instances there are slight halos (especially in non-ideal lighting situations) with these lenses. Most patients do not find these halos to be obtrusive, and find the advantages of having a multifocal implant outweigh any of the slight disadvantages. However, it is still imperative that you and your doctor determine if indeed you are a good candidate for this type of implant. Finally, multifocal implants are designed to be implanted into both eyes. Therefore, the patient will need to commit to having a multifocal implant inserted into each eye within a reasonable period of time.
