Immediately sequential bilateral cataract surgery importance during the COVID-19 pandemic

Abstract

Cataract surgery is one of the most frequently performed types of surgery in the world. Most patients suffer from bilateral cataract and while cataract surgery of only one eye is effective in restoring functional vision, second eye surgery leads to further improvements in health-related quality of life, and is cost effective. At present, most patients undergo cataract surgery in both eyes on separate days, referred to as delayed sequential bilateral cataract surgery (DSBCS). An alternative procedure involves operating both eyes on the same day, but as separate procedures, known as immediately sequential bilateral cataract surgery (ISBCS). The aim of this study is to evaluate the effectiveness and costs of ISBCS compared to DSBCS. ISBCS is an important topic in ophthalmology, especially during the recent COVID-19 pandemic as it is necessary to decrease the hospital visits in order to prevent the contagious risk of this disease. There are well-documented advantages in terms of reduced costs for patients and health-care systems as well as more rapid visual rehabilitation and neuroadaptation. Based on recent studies, the risk of bilateral simultaneous complications is now recognized to be rare with the advent of intracameral antibiotics and strict protocols in this surgical approach. With the use of more sophisticated optical biometry and the newest generation lens calculation, refractive surprises are rare for normal eyes. A widely recognized protocol from the International Society of Bilateral Cataract Surgeons needs to adhere in order to prevent any further complications and obtaining better outcomes.
