What your dad got is an IOL: intraocular lens. These things are pretty amazing these days; they can correct myopia and astigmatism, eliminate cataracts, and eliminate the need for reading glasses too because the new lens is focus-able (in the ones that are "accommodating"). I'm thinking of getting these in 5-10 years, since I'm just starting to have problems with reading now; by that time, new artificial lenses will be a perfect solution to my eyesight problems I can expect to have at that age.
Your dad sounds like one of these annoying non-technical people who hears one technical term (e.g. LASIK) and then applies that in blanket fashion to anything remotely related. He probably calls Android phones "iPhones", and he probably calls laptop computers "iPads", and he probably calls the Internet "AOL".
