Impact of COVID-19 on surgical specialist training as quantified by trainee complication rates for cataract surgery

Reduction in elective surgeries during the COVID-19 pandemic has negatively impacted surgical specialist training. Posterior capsule rupture rate (PCR), a complication of cataract surgery, is an objective measure of the quality of ophthalmic surgery. This study aimed to compare PCR pre- and post-COVID-19 in trainees and consultants.

A single-centre consecutive cases series of cataract surgeries performed at Groote Schuur Hospital, between 1 February 2017 and 31 May 2021 were analysed. Our main outcome measure was the effect of the volume of cataract surgeries on PCRs between ophthalmology trainees and consultants before and after the COVID-19 reduction in elective surgeries on 23 March 2020.

During the study period, 4 157 cataract surgeries were performed (3 493 in the 38 months pre-COVID-19 and 664 in the 14 months post-COVID-19). Fourteen ophthalmology trainees and six consultants performed 2 919 and 1 238 cataract surgeries, respectively. In the trainees the PCR was 4.4% pre-COVID-19 and 10.0% post-COVID-19 (odds ratio [OR] 2.44; p < 0.001; CI 1.71-3.47; relative risk [RR] 2.29). The PCR of consultants remained unchanged with a PCR of 3.4% pre- and post-COVID-19 (OR 1.02; p = 0.97; CI 0.42-2.46; RR 1.02).

COVID-19 has caused a marked reduction in the volume of cataract surgery which has resulted in a deterioration in the performance of trainees, but not consultants, and quantifies the negative impact of the pandemic on surgical training in ophthalmology. This highlights the need to develop plans to improve surgical training during the COVID-19 recovery period.
