[Did the idea of intraocular lens implantation originate on Polish territory?].

The author described the activity of the Italian ophthalmologist Tadini who, during his work in Warsaw in 1765, planned to implant a glass ball into an eye after cataract operation. However, Tadini did not perform this operation. This fact was described in his diaries by Giacomo Casanova. The first implantation of the glass lens was performed by Casaamata in Dresden in 1795.
