Professional profile

Mr Gerassimos Lascaratos is a Consultant Ophthalmic Surgeon specialising in glaucoma and cataract surgery at King’s College Hospital, London. He is an Honorary Clinical Senior Lecturer in Ophthalmology at King’s College London and is the clinical lead for the ophthalmology urgent referral service at King’s College Hospital. He is also an Honorary Senior Lecturer in Ophthalmology at the UCL Institute of Ophthalmology, London.

Gerassimos prides himself on delivering the highest quality patient care with a focus on patient experience and clinical outcomes. He specialises in cataract surgery and in the medical, laser and surgical management of all types of adult glaucoma, including trabeculectomy and aqueous shunt devices, cutting edge minimally invasive glaucoma surgery and glaucoma revision surgery.

His cataract complication rate is less than 0.5 per cent, which is way below the national average, despite the complexity of the operations he performs. He also offers premium intraocular lenses including toric lenses to correct astigmatism and multifocal lenses to reduce spectacle dependence for near and distance.

Gerassimos has a passion for translational clinical research and is currently the Principal Investigator for a large prospective study between Moorfields and King’s College investigating the role of mitochondrial function as a novel biomarker for glaucoma. He is also the Principal Investigator for several multicentre glaucoma commercial trials and NIHR CRN portfolio studies.

Gerassimos completed the South Thames surgical training programme in ophthalmology in London, including subspecialty glaucoma fellowship training at Moorfields Eye Hospital, and has extensive experience in Ophthalmology.

Based on his innovative PhD work in Glaucoma at University College London and MSc work at Oxford University he has unique expertise in cellular bioenergetics in glaucoma and its relevance to the development of new glaucoma treatments. He is the recipient of multiple national and international awards, including the Fight for Sight New Lecturer Award 2017.

He has served as a Member of the European Glaucoma Panel (EGP) IV and Mentoring Programme and is a regular examiner for the Royal College of Ophthalmologists.
