Abstract
Cataract surgery has advanced from a mere replacement of the cloudy lens to a refractive-cataract surgery due to the advancements in diagnostic and surgical instrumentation and techniques. The availability of premium intraocular lenses provides patients the opportunity to regain excellent vision and be less dependent on spectacles. In order to attain the desired postoperative refraction or target emmetropia following cataract surgery, accurate biometry and appropriate intraocular lens power formula selection are required, along with safe and precise surgery. This article reviews the salient features and recent advances in biometry and intraocular lens power calculations.
