We read with interest the article by Naderi et al. [1] and were intrigued by their finding of patients’ shifted preference towards immediate sequential bilateral cataract surgery (ISBCS) as a result of COVID-19. The COVID-19 pandemic has brought enormous challenges to ophthalmic service delivery in United Kingdom (UK) after postponement of elective clinical activities including cataract surgery during the first wave of pandemic (March– June 2020). New strategies are more needed than ever to redesign cataract service to overcome capacity issues, long waiting lists and patient’s fear of increased COVID-19 transmission risk in hospital settings [2]. Not only ISBCS offers advantages of reducing pressure on waiting lists but also reduces hospital visits and COVID-19 exposure risks for patients [3]. The Royal College of Ophthalmologists and UK and Ireland Society of Cataract and Refractive Surgery (UKISCRS) jointly recommended more ISBCS in suitable patients to streamline cataract services [4]. Ophthalmology Department at Sheffield Teaching Hospital followed this recommendation and encouraged its cataract surgeons to utilise ISBCS in appropriate candidates with careful counselling and consenting after the cataract service regained its activities in late July 2020. Here, we evaluated the characteristics of ISBCS case selections pre and post COVID-19 era and aimed to share our experience from both surgeons’ and patients’ perspectives with ISBCS.

A pre-set questionnaire was sent electronically to all the 17 cataract consultants and principals in our institution. A separate six-question patient survey was used to interview patients who had ISBCS during the 6-month period between 1 August 2020 and 31 January 2021 by telephone. All the survey responses were anonymous. Two telephone calls were attempted on a different day for each eligible patient. Verbal consent was obtained at the start of the interview. First-eye patients who required cataract surgery in both of their eyes were searched on Medisoft from 1 August 2020 to 31 January 2021 (post reopening of cataract service) and from 1 February 2015 to 1 February 2020 (before COVID-19) and their pre-op and post-op characteristics were collated. Categorical and continuous variables were tested with chi-squared test and t test respectively with p < 0.05 to justify significance. The study was approved by Clinical Effectiveness Unit in our institution and adhered to the tenets of the Declaration of Helsinki.
