Corneal power measurements by ray tracing in eyes after small incision lenticule extraction for myopia with a combined Scheimpflug Camera–Placido disk topographer

PurposeTo evaluate the accuracy of the measurements of corneal power obtained by ray tracing with a combined Scheimpflug camera–Placido disk corneal topographer (Sirius) in eyes after small incision lenticule extraction for myopia (SMILE).MethodsRetrospective cases study includes 50 eyes of 50 patients who underwent myopic SMILE. Mean value of simulated keratometry (Kpost), mean pupil power (MPP) (ray tracing, diameter of the entrance pupil...
