Abstract Details


to compare phacoemulsification parameters and surgically induced astigmatism through different corneal wound size


Haseki Education and Research Hospital.Turkey


retrospective study. we evaluated 80 eyes of 72 patients that had cataract surgery performed through temporal clear corneal incisions between february-june 2013. we divided them into two groups (2,4 mm and 2,8 mm) keratometry were performed preoperatively, at month 1 and 3. surgically induced astigmatism was calculated by means of vector analysis. phaco time, cumulative dissipated energy and total fluid used were recorded. student's t test and mann whitney u test were used for statistical analysis


there were no statistically difference in intraoculer parameters. phaco time, cumulative dissipated energy and total fluid used were comparable between two groups.(respectively p>0,450 ,p>0,290 ,p>0,137) surgically induced astigmatism in the 2,4 mm group was less than 2,8 mm group at month 1 and 3. (month1: 0,43 D at 2,4mm, 0,67D at 2,8mm, p>0,02) (month3:0,26D at 2,4mm, 0,40D at 2,8mm, p>0,01)


we conclude that smaller incisions may result in less surgically induced astigmatism. FINANCIAL INTEREST: NONE
