Research has been a defining part of Mr Garg's career. He completed a Doctor of Medicine
(MD[Res]) at University College London under the supervision of Professor Gus Gazzard —
ranked among the world's leading ophthalmologists and widely regarded as one of the
foremost authorities in glaucoma — focusing on the clinical outcomes, predictors of
success, and safety of Selective Laser Trabeculoplasty (SLT) in the treatment of
glaucoma. This work was undertaken as part of the landmark multicentre LiGHT Trial,
which Professor Gazzard led, and which directly influenced national guidance on the
first-line treatment of glaucoma in the UK.
He has authored over 25 peer-reviewed publications in leading international journals
including The Lancet, Ophthalmology, Eye, and IOVS, with multiple first and senior
author papers focusing on glaucoma outcomes and laser treatment. His research has been
recognised with several competitive awards and grants, including funding from the Royal
College of Ophthalmologists, the International Glaucoma Association, and Fight for Sight.
Mr Garg has presented his research at national and international ophthalmology meetings,
and was awarded the UK & Eire Glaucoma Society Prize for Best Free Paper in 2019.
That same year, the International Glaucoma Association Award for Excellence in Glaucoma
Care was awarded to the LiGHT Trial Study Group, of which Mr Garg was a member.
Alongside his clinical practice, Mr Garg continues to contribute to ophthalmic research.
He is currently involved as a collaborator in cataract-related clinical trials, with
further publications in preparation — reflecting his ongoing commitment to evidence-based
practice and the advancement of patient care.
