Cataract surgery is the most commonly performed surgical procedure in the UK (approx. 472,000 annually). The suspension of interventions due to the COVID-19 pandemic, has had a devastating impact on patients’ access to care. In the UK a complete cessation of elective cataract surgery during the crisis has been an unfortunate reality and encompassed a 14 week hiatus to services in the National Health Service. Patients on prolonged waiting lists may experience negative outcomes during the wait period, including vision loss, increased risk of falls, and ultimately, poorer health-related quality of life (HRQoL). The objective of this research was to estimate the potential societal costs associated with vision-loss related to prolonged waiting times for cataract surgery, as a consequence of COVID-19 in the UK.

In this analysis, we present estimates relating to two cohorts: a hypothetical cohort of 1,000 cataract surgeries and quarterly estimates of cataract surgeries in the UK. Quarterly estimates (n=122,969) were chosen to reflect a suspension of cataract surgeries for 14 weeks during the COVID-19 crisis. UK cataract surgery numbers were attained from EUROSTAT. Estimates for decreasing visual acuity for those waiting for surgery were attained from the literature, as were the cost estimates associated with cataract-related sight-loss, which were made up of direct, indirect and intangible costs. Five scenarios (at 20% intervals) were simulated for the cost estimates, assuming from 20 percent to 100 percent clearing of waiting lists.

For cohort 1 (1,000 patients), the societal costs associated patients remaining on waiting list for one year, ranged between GBP 237,765 (EUR 279,533) (20% of patients remain untreated) to GBP 1.18m (EUR 1.39m) (100% remain untreated). For cohort 2 (n=122,969) cost estimates are in the region of GBP 29.23m to GBP 146.18m (EUR 34.36m to EUR 171.73m). Estimates consist of direct (15.6%), indirect (28.7%) and intangible costs (55.6%).

Cataract surgery is a sight saving procedure and its impact on HRQoL is overwhelmingly positive. Prolonged waiting times for cataract patients due to COVID-19 is likely to be associated with significant societal costs.
