Tadini, the man who invented the artificial lens.

Tadini, an Italian by birth, was an itinerant ophthalmologist living in the second half of the eighteenth century. The eye operations which he performed at many places throughout Europe are documented by his advertisements in newspapers of the day. It is likely that Tadini was the first to conceive the possibility for intraocular correction of aphakia. At any rate, Casanova's memoirs record a meeting with Tadini and make mention of the oculist's box of artificial glass lenses for placement in the eye. Presumably, Casanova conveyed Tadini's idea to Casaamata, an ophthalmic surgeon in Dresden who was the first to actually attempt correction of aphakia with artificial lens implantation.
