There are several types of intraocular lenses implanted in the eye after cataract surgery, states GetEyeSmart.org. They include monofocal, multifocal, accomodative and intraocular lenses for astigmatism.Continue Reading
There are new technology lenses from the brands ReSTOR, ReZoom and Crystalens, explains vision expert Dr. Troy Bedinghaus, for the American Academy of Opthamology. The specific lens is selected by the doctor according to patients' goals and the doctor's experience. These implants are effective in helping the patient see clearly at almost all distances.
Before surgery, the patient's eyes are measured to determine the correct intraocular prescription, notes Dr. Bedinghaus. The type of implant chosen affects how the patient will see after cataract surgery and whether or not glasses will still be needed for certain activities. Some patients decide on a different monofocal for each eye, one being for long distance and the other for near vision. This often reduces the need for glasses as the brain processes the information from both eyes because of the correction built into the lens.
Patients with intraocular lenses for astigmatism, a condition that distorts or blurs near and distant objects, find different degrees of satisfaction with toric intraocular lenses. These lenses reduce and possibly eliminate the need for glasses, details Dr. Bedinghaus.Learn more about Vision
