Cataract surgery is the most performed surgery in ophthalmology and remains as the ultimate refractive surgery. It offers an opportunity to improve a patient's visual acuity and target a degree of spectacle independence. The process of intraocular lens (IOL) calculations serves as a crucial element in achieving successful post-operative refractive outcomes. A modern-day surgeon has access to several IOL formulas to pick the most appropriate lens to achieve a desired target refraction. These formulas, however, have both advantages and limitations and therefore reach within 0.50 diopters of the target refraction only 70-80% of the time. There is a lack of a single, ideal formula that can simplify complexities of this process and achieve higher degrees of accuracy. The development of the IOL Ladas 'super formula' may provide a simplistic, accurate, and ever-evolving solution to improving outcomes.
