Until recently, patients undergoing lens implant surgery received a monofocal, or single focus IOL. Monofocal IOLs implanted in both eyes generally provide excellent distance vision, while patients often need spectacle correction for near and intermediate vision. In the late 1990s, Advanced Medical Optics (AMO) introduced its first multifocal IOL designed to provide multiple points of focus, thereby dramatically reducing the need for bifocals or trifocal glasses after surgery.
Today, with many optical design enhancements, Multifocal IOL's are providing patients with a full range of vision and greater independence from glasses or contact lenses than ever before. Clinical studies show that 92% of those receiving multi-focal technology “never”, or “only occasionally,” need to wear glasses.
If you suffer from poor vision, or think you might have a cataract, you should make an appointment to have a complete eye examination. Once it is determined that you are a good candidate for the multifocal IOL, you will be given additional information about the possible risks, complications, and costs involved with the procedure. Be sure to have all of your questions answered before giving your consent to have surgery.
