Alex Day: Innovator in Cataract and Laser Vision Correction Surgery

Mr Alex Day is an honorary clinical Associate Professor at University College London and has over 70 publications. He is a PhD student supervisor. Being research trained means he can offer his patients the latest treatments to give them the best surgical outcomes and customer service.

Alex’s reseach publications have been cited over 3000 times, his h-index score is 31 and his i-10 index score is 68 on Google Scholar.

Alex Day is internationally recognised for his research in cataract and lens replacement surgery. He was ranked no.2 globally by The Ophthalmologist as a Rising Star in 2017.

Alex is an Honorary Associate Professor at UCL Institute of Ophthalmology, London. He has published 70 papers in peer reviewed medical journals and is first author for 39. He was responsible for the concept and formation of the group behind the Femtosecond laser Assisted Cataract Trial (FACT). This was a £1.5 million NIHR funded multicentre randomised controlled trial of femtosecond laser assisted cataract surgery (FLACS) vs conventional phacoemulsification cataract surgery (standard ultrasound cataract surgery).

Alex was the Principle Investigator at Moorfields for the £1.1 million NIHR DemDx A&E Artificial Intelligence Triage Platform study.

Alex is the Moorfields joint lead for cataract surgery research, including a collaboration with Aston University for UK Biobank analysis of the genetics of cataract. He is also the first author of four RCOphth National Ophthalmology Database publications using big data to benchmark and set national standards for cataract surgery outcomes.
