The Royal College of Ophthalmologists' National Ophthalmology Database study of cataract surgery: report 19, a comparative study of the cost and carbon footprint of local anaesthesia techniques for cataract surgery.

Background: Understanding the financial and environmental impact of clinical pathways is important for designing sustainable services. This study aimed to compare the cost and carbon footprint of sub-Tenon's and topical anaesthesia for cataract surgery, benchmark minimum topical anaesthesia utilisation rates, and quantify the benefits of increased topical anaesthesia usage in the United Kingdom National Health Service (NHS).

Methods: The cost and carbon footprint of products and staffing for topical and sub-Tenon's anaesthesia for cataract surgery were calculated and applied to National Ophthalmology Database audit data.

The Royal College of Ophthalmologists' National ophthalmology database study of cataract surgery: Report 14, cohort analysis - the impact of CapsuleGuard® utilisation on cataract surgery posterior capsule rupture rates.

Background/objectives: The aim of this study was to investigate whether the use of the silicone tipped irrigation/aspiration (I/A) handpiece CapsuleGuard® (Bausch + Lomb, Laval, Canada) reduced rates of posterior capsule rupture (PCR) during cataract surgery.

Methods: Royal College of Ophthalmologists' National Ophthalmology Database (NOD) Cataract Audit data from 01/04/2010 and 31/03/2021 and Bausch + Lomb sales figures were combined to identify centres participating in national cataract audit who have routinely adopted the silicone tipped I/A handpiece, CapsuleGuard®. Data were included only from centres with eligible cataract operations recorded on the NOD both before and after adopting CapsuleGuard®.

The Royal College of Ophthalmologists' National Ophthalmology Database Study of Cataract Surgery: Report 13, monitoring post-cataract surgery endophthalmitis rates-the rule of X.

Background: Cataract surgical safety has improved over recent decades, with endophthalmitis rates before 2006 typically 0.13-0.15% compared with the most recent UK national estimate of 0.

Progression from ocular hypertension to visual field loss in the English hospital eye service.

Background: There are more than one million National Health Service visits in England and Wales each year for patients with glaucoma or ocular hypertension (OHT). With the ageing population and an increase in optometric testing, the economic burden of glaucoma-related visits is predicted to increase. We examined the conversion rates of OHT to primary open-angle glaucoma (POAG) in England and assessed factors associated with risk of conversion.
