How does lens implant work?

A lens implant, often used in cataract surgery, involves replacing the eye's natural lens with an artificial intraocular lens (IOL). During the procedure, the cloudy natural lens is removed, and the IOL is inserted into the eye, where it helps focus light onto the retina, restoring clear vision. These implants can be tailored to correct various refractive errors, such as nearsightedness or farsightedness, and may be designed for multifocal vision to reduce the need for glasses. The lens is typically made of biocompatible materials, ensuring safety and durability within the eye.
