During cataract surgery, which device is implanted to restore vision?

Explanation:
The main concept is that cataract surgery restores vision by replacing the cloudy natural lens with an artificial one. The implanted device, an intraocular lens, takes over the eye’s focusing power and sits in the lens position to transmit light to the retina. A contact lens sits on the cornea, not inside the eye; a corneal graft replaces the cornea, not the lens; and a retinal prosthesis targets the retina itself, not the lens, so none of those are used to restore vision during cataract removal.
