Mr. Barton pioneered in aqueous shunt surgery in the United Kingdom. He received a number of awards for his achievement in the field of ophthalmic surgery and has been voted twice by The Ophthalmologist magazine as one of the 100 most influential people in Ophthalmology. His prospective study titled “Corneal endothelial cell loss in eyes implanted with Baerveldt Glaucoma Implant” was rewarded the 2020 Best Paper at the American Glaucoma Society.

He is actively involved in surgical teaching, patient education and charitable projects. He has produced patient information on aqueous shunt implantation and trabeculectomy that are available online in several languages and which have been awarded the NHS Information Standard in the UK. He also has established an online resource to help patients and clinicians navigate the proliferation of new glaucoma surgical devices as well as an internet-based International Registry of Glaucoma Surgery, in order to collect outcome information on all types of glaucoma surgery from around the world.
