[Simulation of toric intraocular lens results: the effect of repeatability and increments of automated keratometry].

Objective: To study the repeatability and scale increments of automated keratometry and their influence on the use of the toric intraocular lens (IOL) and on astigmatism correction.

Method: The study enrolled 131 eyes of 82 patients. Preoperative corneal astigmatism was measured in the different (0.
