With an estimated number of 180,000 cataract extractions per year in the Netherlands, cataract surgery is one of the most frequently performed types of surgery. The majority of patients suffer from bilateral cataract and while cataract surgery of one eye is effective in restoring functional vision, second-eye surgery leads to further improvement in health-related quality of life.~Currently, most patients undergo cataract surgery in both eyes on separate days as recommended in national guidelines, referred to as delayed sequential bilateral cataract surgery (DSBCS). An alternative procedure involves cataract surgery of both eyes on the same day, but as separate procedures, known as immediately sequential bilateral cataract surgery (ISBCS).~Potential benefits of ISBCS include less time between surgeries, a faster total recovery period and lower costs. Potential risks, however, are complications of cataract surgery in general, most importantly the risk of endophthalmitis and refractive surprise. In ISBCS, both eyes are at risk at the same time, while in DSBCS both eyes are exposed to these risks consecutively.~Since there is no consensus yet about the role of ISBCS in current regular practice, further investigation of functional and surgical outcomes and cost-effectiveness of ISBCS compared to DSBCS is required. Therefore, the purpose of this study is to evaluate the effectiveness and costs of ISBCS compared to DSBCS, in order to determine whether ISBCS is an effective and cost-effective alternative to DSBCS.
