Coronavirus: eye department update

In response to the coronavirus (COVID-19) outbreak, please follow our advice before attending the service.

Our service

The department of ophthalmology is based at St Thomas’ Hospital and sits within the directorate of medical specialties at Guy's and St Thomas' NHS Foundation Trust.

We treat a wide range of eye conditions in adults, young people and children.

For emergencies we offer a specialist eye rapid access service in the eye department at St Thomas’ Hospital. The service opens at 8.45am to register patients with the clinic running from 9am to 4pm, Monday to Friday excluding bank holidays. At all other times, patients with eye emergencies need to attend the emergency department (A&E) at St Thomas’ Hospital.

If you live in the Boroughs of Lambeth, Lewisham or Southwark, we partner with local optometrists for the minor eye conditions service (MECS).

We have a strong research background and are a major teaching and training unit for both undergraduate and post graduate ophthalmologists, optometrists, orthoptists, ophthalmic nurses, ophthalmic imagers and ophthalmic technicians from all over the world.


Harold Ridley plaqueThe Ridley clinic was named after Sir Harold Ridley, who pioneered artificial intraocular lens implantation after cataract surgery. He performed the first implantation here in 1950.

St Thomas’ was also the first place in the UK where laser refractive surgery was carried out.

New treatment to prevent blindness

A pioneering device which helps fluid to drain from the eye is being used in a trial at St Thomas’ Hospital in the hope that it will save patients’ sight. Surgeons are using a special blade to treat patients with glaucoma, a common age-related condition which can lead to blindness and affects around half a million people in England. The device is being trialled as part of a small clinical study at St Thomas’ Hospital.
