RESUMEN
PURPOSE: To describe variation in local anesthesia techniques and complications over a 10-year period for cataract surgery in the United Kingdom. SETTING: Reporting centers to the Royal College of Ophthalmologists (RCOphth) National Ophthalmology Database (NOD). DESIGN: Retrospective cross-sectional register-based study. METHODS: Data from the RCOphth NOD were used. Eligible for analysis were 1 195 882 cataract operations performed using local anesthesia between April 1, 2010, and March 31, 2020, in 80 centers. RESULTS: Overall, topical anesthesia alone was used in 152 321 operations (12.7%), combined topical and intracameral in 522 849 (43.7%), sub-Tenon in 461 175 (38.6%), and peribulbar/retrobulbar in 59 537 (5.0%). In National Health Service (NHS) institutions, 48.3% of operations were topical with/without intracameral vs 88.7% in independent sector treatment centers (ISTCs). 45.9% were sub-Tenon in NHS vs 9.6% in ISTCs. 5.8% were peribulbar/retrobulbar in NHS vs 1.7% in ISTCs. Anesthetic complication rates decreased from 2.7% in the 2010 NHS year to 1.5% in the 2019 NHS year (overall, 2.1% for NHS; 0.2% for ISTCs). Overall anesthetic complication rates were 0.3%, 0.3%, 3.5%, and 3.1% for topical alone, combined topical/intracameral, sub-Tenon, and peribulbar/retrobulbar, respectively. Complication rates were higher for sharp-needle anesthesia (peribulbar/retrobulbar) in patients taking warfarin rather than direct oral anticoagulants (4.8% vs 3.1%; P = .024). Considerable variation was observed between centers on anesthetic choices and anesthetic complication rates. CONCLUSIONS: Combined topical and intracameral is the most common choice of anesthesia for cataract surgery in the United Kingdom and is associated with lower anesthetic-related complication rates than sub-Tenon and peribulbar/retrobulbar anesthesia. Variation in the anesthetic choice exists between centers and between NHS and ISTC sectors.

AIMS: To explore trends over time and variation in the use of anaesthetic techniques for vitreoretinal (VR) surgery in the UK. METHODS: Prospectively collected data from 13 centres contributing >50 VR operations, including either pars plana vitrectomy (PPV) or scleral buckle (SB), between May 2000 and November 2010 were retrospectively analysed. Anaesthesia was categorised as general anaesthesia (GA) or local anaesthesia (LA) and results were reported by year, centre, grade of surgeon and type of operation. RESULTS: 160 surgeons performed 12â 124 operations on 10â 405 eyes (9935 patients); 6054 (49.9%) under GA and 6070 (50.1%) under LA. The percentage performed under GA decreased from 95.3% in 2001 to 40.9% in 2010. Within LA techniques, peribulbar or retrobulbar injection was used in 2783 (45.8%) operations and sub-Tenon's cannula in 3287 (54.2%). The proportions of operations performed under GA or LA were similar for consultants and trainees. Primary SB, primary combined PPV and SB for retinal detachment (RD), repeat RD surgery and complex vitrectomy surgery were more commonly performed under GA (85.8%, 67.0%, 63.5% and 69.4%, respectively), while primary PPV for RD, simple vitrectomy surgery and macular surgery were more commonly performed under LA (58.1%, 53.7% and 58.2%, respectively). Marked intercentre variation existed with the extremes being one centre with 100% of operations performed under GA and one centre with 98.3% under LA. CONCLUSIONS: LA for VR surgery has steadily increased over the last decade in the UK but marked intercentre variation exists.
