Cataract surgery today has become more of a refractive surgery with high patient expectations and demand for independence from glasses. With advances in biometry, precise intraocular lens (IOL) power calculation is the most important step in achieving desired target refraction. Noncontact optical biometry has become the gold standard worldwide with a few exceptions where contact ultrasound biometry still needs to be performed. Although there is no single formula for IOL power calculation suitable for all eyes, our understanding of which formulae to use in specific situations is much better. Despite advances in biometry and cataract surgery techniques, unsatisfactory visual and refractive outcomes occur occasionally. Enhancement after cataract surgery is required in these cases. The common methods to treat such cases are corneal-based laser refractive surgery or lens-based procedures such as piggyback IOL and lens exchange.
