Cataract Surgery to Improve Unaided Near, Intermediate and Distance Vision
Traditional cataract surgery involves placement of a monofocal lens implant. This is the most common type of lens used with cataract surgery and is commonly called a monofocal IOL. It has one focusing distance. It is set to focus for up close, medium range or distance vision. Most people have them set for clear distance vision. Then they wear eyeglasses for reading or close work.
These IOLs provide both distance and near focus at the same time.This involves placement of a Multifocal implant to provide “full focus” vision at all distances. The lens has different zones set at different powers. It is designed so that your brain learns to select the right focus automatically. Changing the implant position in the eye adjusts the lens focal length.
