To perform a reference case cost-utility analysis of second-eye cataract surgery by using the current literature on cataract outcomes and complications. ⋯ Second-eye cataract surgery is an extremely cost-effective procedure when compared with other interventions across medical specialties. The cost-effectiveness of second-eye surgery diminishes only slightly from the 2023 US dollars per QALY gained from first-eye cataract surgery. This suggests that patients with good vision in one eye and visual loss from cataract in the fellow eye derive substantial benefit from cataract extraction.
