Intraocular lens implant is a surgical procedure to treat the cataract. The surgery involves removing the cloudy lens and replacing them with the artificial lens called IOL, or intraocular lens. An IOL is a clear, plastic lens that can easily be made a permanent part of your eye after the surgery. It is a safer way to restore the vision and does not have any complications in the surgery. Another option is to wear the lenses, but since the contact lens can be difficult for most people, opting for surgery is a better option.
