The aim of the study was to determine the prevalence, distribution and types of corneal astigmatism in cataract surgery patients in Šibenik County. In this retrospective study, keratometric data on 392 eyes of 202 patients admitted for senile cataract surgery to Šibenik General Hospital from April until June 2011 were collected and statistically analyzed. The median age of our patients was 77 range 50 to 92 years; there were 91 45% men and 111 55% women. The measured keratometric values ranged from 36.00 to 47.00 diopter. The median of measured corneal astigmatism was 0.75 diopter cylinders DCyl, ranging from 0 to 6.12 DCyl. In 150 38.3% study eyes, corneal astigmatism was in the physiological range of 0.50 DCyl or less, in 118 30.1% eyes it was >0.50-1.0 DCyl, and in 124 31.6% eyes >1.0 DCyl. Preoperative corneal astigmatism of 1 DCyl or more has a significant influence on postoperative refractive outcome. This imposes the need to consider a possible option for correction of preoperative astigmatism at the time of cataract surgery.
