Sir Harold Ridley is well known for his pioneering intraocular lens implantation surgery. He also had a significant commitment to the televising and filming of surgery. In his 1950 Television in Ophthalmology paper, Ridley describes the techniques he used to capture his surgery in monochrome and later in full colour for audiences at St Thomas' Hospital.
