PRELEX - stands for presbyopic lens exchange.

It is the term to describe lens replacement surgery in patients who require reading glasses prior to the development of significant sight reducing cataract. In actual fact, the aging change of a lens reducing near vision can be thought of as an incipient cataract. Surgery can be performed at this time to replace the aging lens and substitute it with a multifocal lens that can allow for clear near and distant vision.

Please note that there are two types of premium lens exchange options: Premium Multifocal Lenses and Toric Lenses for Astigmatism.
