Multifocal Introduction
Intraocular lenses - also called IOLs - come in two varieties: monofocal and multifocal. Originally, IOLs were monofocal or corrective of vision at one distance only, whether near, intermediate, or far. Since they correct vision at just one distance, glasses are still needed--especially if the patient suffers from presbyopia (age-related farsightedness).
Newer multifocal intraocular lenses will correct vision at multiple ranges which means that you will be able to see distance and up close without glasses. To do this, the multifocal IOL creates multiple focal points allowing an individual to see better at a variety of distances. A multifocal IOL can improve an individual's overall vision, allowing objects to appear sharper and clearer.
Multifocal IOLs are an excellent option for individuals who suffer from eye diseases such as cataracts and presbyopia. The multifocal lens is designed to treat these ailments, improve vision, and decrease a dependency on prescription glasses or contact lenses.
Amazing Results
For patients with cataracts, a multifocal lens will replace the cataract-impaired lens providing improved vision almost immediately. This surgery is generally low risk and takes about 5-10 minutes to complete. It offers a safe, quick, and effective way to repair the patient's vision, and patients can resume activities the next day in many cases.There are several benefits of multifocal lenses, including:
- Improves vision for objects close up and in the distance
- Provides good vision in a variety of lighting conditions
- Requires no sutures
- Successful treatment for cataract patients
- Allows patients to get rid of their glasses and contact lenses
- Reading
- Seeing up close
- Seeing at a distance
- Driving, particularly at night
The IOL Procedure
The IOL replacement procedure is performed on an outpatient basis. The eye(s) is treated with anesthetic to limit any discomfort. A tiny incision is made at the edge of the eye and the natural lens is removed. The monofocal or multifocal lens implant is then inserted through the same tiny incision.
Am I a Candidate?
Individuals who may be a candidate for multifocal lenses have difficulty with one or more of the following:
Although IOLs are contraindicated for individuals who have particular medical conditions, most people between the ages of 21 and 80 who are suffering from cataracts or presbyopia and have healthy eyes are good candidates for intraocular lenses.
Multifocal lenses offer patients exciting new treatment options not only for those suffering from cataracts, but also for those who are looking to decrease or eliminate their dependency on glasses and/or contact lenses.
