When the natural lens is removed during cataract surgery, it must be replaced with an intraocular lens. There are two types of intraocular lenses, Single Focus and and Multi Focus Lenses. Patients now have the opportunity to make an informed decision as to which lens and visual outcome they want.
Single Focus Intraocular Lenses
A single focus or monofocal intraocular lens is considered the traditional lens which has been used in cataract surgery for the last 30 years. This lens is one that corrects only for distance vision unless you have astigmatism in which case even the distance is blurred. Usually these patients have crisp distance vision, but have to wear glasses for both intermediate and near vision. This is a great lens for patients who want good distance vision and don’t mind wearing glasses.
Multi Focus Intraocular Lenses
As we perform daily activities such as reading, watching television or working at the computer, our eyes are constantly focusing on objects at varying distances – up close, far away and everything in-between. However, as we age, the ability of our eyes to focus weakens, resulting in the need for bifocals and reading glasses. Multifocal Intraocular Lenses (IOLs) are FDA-approved lenses which give patients clear vision at many distances: near, intermediate and far. Imagine the greater overall freedom of being free of glasses!
Multifocal IOLs are implanted during cataract surgery to replace the natural lens. There are several options available when it comes to choosing a multifocal IOL. Each has unique attributes that may or may not be of benefit to your vision correction goals. At The Nielsen Eye Center, we are happy to offer the latest in multifocal lenses in cataract surgery. We offer four IOL options, each designed for a specific corrective function:
