A variety of lenses can be placed in the eye at the time of cataract surgery, including: conventional implants, astigmatism correcting implants, and accommodating or bifocal lenses. These lenses are also known as IOLs, or intraocular lenses.
Intraocular Lens Options for Cataract Patients include:
- Traditional Implant Lens - TECNIS™ Monofocal Lens
- Astigmatism Correcting Implant Lens - AcrySof® Toric Lens
- Accommodating or Bifocal Implant Lens - Crystalens® HD Lens
Traditional/Convential Implant Lenses
TECNIS lensTecnis Conventional Implant Lenses are also known as Monofocal Lenses. These intraocular lenses correct vision for a specified distance. Eyeglasses are often needed after cataract surgery if a conventional, monofocal lens is used.
An example of a single piece, intraocular, monofocal lens is the TECNIS™ lens, pictured on the left.
Astigmatism Correcting Implant Lens
Acrysof Toric Lens alcontoricIn addition to correcting for nearsightedness (myopia) or farsightedness (hyperopia), these lenses also help compensate for astigmatism after cataract surgery.
Glasses are needed less frequently when these implant lenses are used. An example of an astigmatism correcting implant lens is the AcrySof® Toric lens, pictured on the right.
Accommodating or Bifocal Lenses
Bifocal Lens pic of lens here.....The third type of IOL available to cataract patients is the accommodating or bifocal lens. These lenses not only correct distance vision, but also provide intermediate and near vision.
An accommodating or bifocal lens provides the best chance of independence from eye glasses following cataract surgery. An example of an accommodation or bifocal lens is the Crystalens® HD.
