Purpose: To evaluate surgically induced astigmatism as computed by means of either simulated keratometry (KSIM) or total corneal refractive power (TCRP) after temporal incisions. Methods: Prospective observational study including 36 right eyes undergoing cataract surgery. Astigmatism was measured preoperatively during the 3-month follow-up period using Pentacam. Surgically induced astigmatism was computed considering anterior corneal surface astigmatism at 3mm with KSIM and considering both corneal surfaces with TCRP from 1 to 8mm (TCRP3 for 3mm). The eyes under study were divided into two balanced groups: LOW with KSIM astigmatism <0.90D and HIGH with KSIM astigmatism ≥0.90D. Resulting surgically induced astigmatism values were compared a...
