Arnott was educated at
Harrow School (Elmfield) and
Trinity College, Dublin where he was awarded the Surgical Prize in 1952; BA (Hons) 1953 and MB (Hons), BCh (Hons) and BAO (Hons) 1954. He gained his Diploma in Ophthalmology (DO) in 1956 and Fellowship to the
Royal College of Surgeons (FRCS) in 1963. Arnott's first ophthalmic appointment was as Houseman at the
Royal Adelaide Hospital and
Royal Victoria Eye and Ear Hospital, Dublin, following which he held early appointments at
Moorfields Eye Hospital, London, and
University College Hospital London, where he trained under
Sir Stewart Duke-Elder and
H. B. Stallard. Whilst at Moorfields he worked with
Sir Harold Ridley, the inventor of the intraocular lens; Arnott was inspired by Ridley's work on the
intraocular lens and they later became lifelong friends. After completing training at
University College Hospital, Arnott was appointed as consultant initially to the
Royal Eye Hospital and later, in 1965, to
Charing Cross Hospital; then still in the Strand. In 1973 the hospital moved to its current site in
Fulham, where Arnott was responsible for setting up the ophthalmic surgical services. In 1974, Arnott and his wife Veronica organised the first Live International Ophthalmic Micro-Surgical Symposium in Charing Cross Hospital, where ten of the world's top eye surgeons performed live surgery, relayed to over 300 international delegates, courtesy of the
BBC. This novel concept in advanced surgical teaching set a standard for future surgical conferences. He later organised two other live symposia with Professor Emanuel Rosen, with the objective of bringing new ideas in
cataract surgery to a wider audience. Arnott was known for his pioneering work in ophthalmology and many of today's top eye surgeons were trained by him whilst registrars at Charing Cross. He retired from the
NHS in 1994. == Phacoemulsification ==
