Effect of surgical abstinence on the risk for posterior capsule rupture during cataract surgery.

ABSTRACT

PURPOSE: To evaluate the impact of surgery restrictions on cataract surgery performance. SETTING: Moorfields Eye Hospital, NHS Foundation Trust, London, United Kingdom. DESIGN: Retrospective, observational cross-sectional study. METHODS: A single-center, retrospective review of all patients who underwent phacoemulsification surgery at Moorfields Eye Hospital between September 2019 and January 2021 was conducted. The main outcome measure was posterior capsule rupture (PCR) rate before and after COVID-19-imposed restrictions to elective cataract surgery. RESULTS: A total of 15 688 surgeries were performed by 256 different surgeons in the study period. In the prerestriction period (September 2019 to March 2020), the PCR rate was 0.99%, whereas in the 19-week postrestriction period, the PCR rate spiked to 1.62% (odds ratio 1.65; P = .001; CI 1.24 to 2.20; relative risk 1.64). CONCLUSIONS: The COVID-19 pandemic provided a unique opportunity to assess a large group of surgeons' performances after prolonged surgical abstinence. A 19-week restriction period in surgical activity showed an increased incidence of PCR complications. This is relevant because it can concern any surgeon on the extended time off from work such as sick, sabbatical, research, and parental leave. Supporting strategies should be implemented by associated regulators to minimize this negative impact.
