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

He also performs sub-2mm “micro-incision” cataract surgery. Steven 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 using LENSAR.
