Multifocal IOLs are a type of lens implant used in cataract surgery. During cataract or lens replacement surgery, the patient’s natural lenses are replaced with multifocal IOLs. These new lenses improve near, intermediate, and far-distance vision.
Etched onto the surface of the multifocal lens are concentric rings, which allow images at a variety of distances to focus on the retina. Ultimately, multifocal IOLs provide restored visual function and reduce or eliminate the need to wear corrective eyewear.
The intraocular lens (IOL) covered by Medicare only corrects vision at a single focus, such as distance. This means glasses are required for all computer use and near vision.
In addition, the “standard” lens does not correct a common problem known as astigmatism, which if present to a significant degree, will require you to wear eyeglasses even to see distance clearly.
Multifocal lenses come with astigmatism correction where needed, and thus offer the broadest range of vision correction available, and the greatest freedom from glasses.
