Background Information 
Professional profile:

Mr Steven Harsum is Opthalmology Clinical Lead at Epsom & St Helier University NHS Trust and is a UK trained eye surgeon (ophthalmologist) working within Surrey.

During his medical degree he was selected for the prestigious MBPhD course at University College London. This involved fast-track medical training, combined a second degree, and a 3 year research doctorate (PhD). His doctorate involved pioneering research into wound healing. During this time he developed his passion and skills for microsurgery.

After specialising in Ophthalmology he trained in multiple hospitals in north and south London, spending the final 2 years at the world renowned Moorfields Eye Hospital as a fellow in medical and surgical retina.

Since starting at Epsom & St Helier Mr Harsum has introduced the latest micro-incision cataract and vitreoretinal surgery. He performs 25 gauge sutureless daycase vitrectomy surgery. This is used to treat a wide variety of conditions such as floaters, vitreous haemorrhage, diabetic retinal scarring, detached retinas, epiretinal membranes and macular holes. He also performs sub-2mm “micro-incision” cataract surgery and femtosecond laser cataract surgery. Compared to standard surgery, micro-incision surgery is less traumatic, faster, and safer for the patient. Surgery can be performed using only anaesthetic drops, rather than an injection to numb the eye. This surgery is combined with the latest multifocal lens implants to give outstanding vision for both near and distance without the need for glasses. After standard cataract surgery, available on the NHS, you will almost always need glasses. Mr Harsum is one of only a handful of surgeons in south east England using such small incision surgery. He is also the first surgeon in the UK to perform combined laser cataract surgery with vitrectomy surgery.

At Epsom & St Helier Mr Harsum was instrumental in starting up the new macular degeneration treatments, with systematic one-stop-shops and dedicated failsafe.Mr Harsum was previously the Clinical Lead of the Diabetic Retinal Screening Service in Sutton & Merton,  Audit Lead at Epsom & St Helier Ophthalmology, aiming to monitor and improve the quality of patient care and outcomes and  College Tutor, responsible for delivering training to ophthalmologists.  Mr Harsum regularly acts as an external quality assurance inspector, assessing the performance of other UK eye units.   Mr Harsum is passionate about both teaching and modern technology, incorporating his videos of operations and special imagery into his tutorials.
