Background: Immediate Sequential Bilateral Cataract Surgery (ISBCS) is not widely performed; however, the COVID-19 pandemic has rapidly altered the risk benefit profile of this surgical procedure. Methods: The literature search was undertaken on March 04th, 2021. The databases used included EMBASE, CINAHL, EMCARE, Medline and PubMed. Findings: By operating on both eyes at one sitting, one outpatient visit and one surgical visit to the hospital is saved, reducing the potential exposure to COVID infection by 50%. As cataract surgery is the most common operation world-wide, this change could potentially save almost 10 million hospital visits per year. ISBCS is widely used internationally (Finland 40%, Sweden 40%) and privately in the UK. This is due to a number of reasons including clinical concern about the risk of bilateral endophthalmitis, postoperative refractive surprise, and there being no set national tariff for provider reimbursement. Summary: The risk to benefit ratio’s for ISBCS, has been shifted by COVID-19 pandemic. The development of one stop cataract surgery, may mean that in future the patient will only visit the hospital on one occasion for their surgery and their pre- and post-op care being delivered by telemedicine, delivering all the benefits of ISBCS while reducing the risk of COVID infection while lowering the carbon footprint cause by ophthalmology.
