What Are Multifocal Lenses?
Multifocal lenses use multiple refractive zones built in rings to give patients distance and near vision. These lenses are designed to address the problem of presbyopia, in which people over the age of 40 begin to lose their ability to read or see up close.
Single Focus IOLs vs Multifocal IOLs
In the past, when an artificial lens, called an intraocular lens implant or IOL, was placed inside the eye during cataract or lens-replacement surgery, it could only focus at a single distance. These IOLs are called single-focus IOLs and allow an eye to see either far away or close-up but not both. Now, intraocular lenses, called multifocal IOLs, are available.
These lenses provide correction for both near and distance vision. And both near and far objects can be in focus at the same time. Many people get used to multifocal IOLs right away. Other people feel a little imbalanced at first but get use to it within a matter of days or weeks.
Are You a Candidate?
You might be a candidate for multifocal or accommodative lens if you are farsighted or nearsighted with minimal astigmatism and wear reading glasses. An exam with our refractive surgeon will determine if these new lenses are appropriate for your eyes.
