The study assesses and compares the accuracy of IOL formulas using keratometry (K) and total keratometry (TK) values obtained by a swept-source OCT biometer (IOL Master 700) in eyes with previous PKP prior to cataract surgery.

There is considerable variability in variables when measuring the eyes with both biometers, which may affect formula performance and postoperative refractive predictions when using formulas that utilize values like interior chamber depth and lens thickness.
