Ridley intraocular lens

The Ridley intraocular lens (IOL) was the first intraocular lens ever inserted into human patients. Harold Ridley developed these working in London in the 1950s and was subsequently knighted for his achievements.

The Ophthalmology section at the Department of Medicine has an example of a Ridley intraocular lens, photographed below, which came to the University of Otago from Professor John Parr.

Professor Parr was head of the former Department of Ophthalmology, and worked as a registrar under Ridley in London.
