Objective: To assess ocular biometric parameters by optical biometry and to observe a possible spherical refractive difference, as well as its variation based on estimated preoperative calculation and the spherical refraction post cataract surgery by phacoemulsification with intraocular lens implant (IOL). Methods: After reviewing 252 electronic medical records between 2013 and 2014, 117 adult patients (189 eyes) were selected.The patients underwent phacoemulsification with foldable IOL implantation by the same surgeon and were examined by IOLMaster® 500.The IOL power was calculated […]
