When the natural lens is removed, the replacement is an intraocular lens implanted inside the eye during cataract surgery. An IOL can be monofocal, providing a single clear focus (often set for distance, with reading glasses needed for near tasks), or multifocal, offering multiple focal powers to help see at various distances with less dependence on glasses. The other terms don’t fit this scenario: phacoemulsification is the technique used to remove the cloudy lens, radial keratotomy reshapes the cornea to change refractive power, and an ocular prosthesis is a cosmetic replacement for an absent eye.
