Intraocular Lenses – Multifocal and Monofocal Lens Implant
Intraocular lenses- also called IOLs - come in two varieties: monofocal and multifocal intraocular lenses. IOLs are implantable lenses that replace the lens of the eye when it is removed during cataract surgery. 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 (or age-related farsightedness). Newer, multifocal intraocular lenses will correct vision at multiple ranges, without the use of glasses or regular contact lenses.
If you are considering cataract surgery to replace the lens in your eye, you should discuss with your doctor which of the different types of IOL may work best for you. There are two main types of IOL to consider: monofocal and multifocal intraocular lenses.
A multifocal lens implant is designed for the correction of both near and far vision. Your brain must learn to select the visual information it needs to form an image of either near or distant objects, so multifocal lenses may require a period of adjustment. A person may adjust better to multifocal intraocular lenses if they are placed in both eyes.
The IOL procedure is performed on an outpatient basis, usually requiring just a few hours to complete. The eye(s) is treated with anesthetic to limit any discomfort. A tiny incision is made at the edge of the eye and the cataract is removed. The monofocal or multifocal lens implant is then inserted through the same tiny incision.
Benefits of Intraocular Lenses: Millions of people around the world who have suffered vision loss due to cataracts or presbyopia are now enjoying the benefits of intraocular lenses. Intraocular lenses provide remarkable vision improvement; a multifocal lens implant can alleviate the effects of presbyopia and eliminate or greatly reduce the need for reading glasses or contact lenses.
