A Multifocal IOL In The Eye
The primary goal of cataract surgery is to remove the cloudy lens, caused by cataracts and replace it with an artificial lens, restoring vision. However although patients notice great results for their long distance vision, there is no improvement for short vision, and there is a need to continue wearing reading glasses.
Nowadays, patients can have the option of multifocal intraocular lenses (IOL) that correct short vision, long vision and distances in-between. Unlike multifocal contact lenses, they don’t need regular care or replacement.
Many patients who have multifocal IOLs find that they don’t need to wear glasses after cataract surgery, or if they do, they may only need reading glasses for very fine print.
