Intraocular lens implants, or IOLs, replace the eye’s natural crystalline lens after cataract surgery or clear lens exchange. Traditionally, the surgeon would select IOLs for each patient based on what would help the patient achieve the best possible distance vision, and the patient would be told to expect to need reading glasses for close work after surgery.
Beginning in the 1990s, however, a new type of lens implant was developed: the multifocal IOL, which featured zones of added refractive power in the lens itself. These new IOLs promised improved vision at all distances, and have been subject to constant refinement and improvement in the years since their introduction. Today newer, high-tech multifocal IOLs such as the Tecnis MF can reduce, or in many cases completely eliminate, the need for reading glasses after surgery. Multifocal IOLs have the advantage of outstanding post-operative vision at a wide variety of distances, but they do represent an additional cost over the conventional procedure. Also, not all patients are good candidates for multifocals; only an experienced surgeon can determine whether they would be of benefit. At your initial cataract examination at Hoopes Vision, the surgeon will discuss with you whether the Tecnis MF is a good option for your unique eyes and visual needs.
