Comparison of surgically induced astigmatism (SIA) values using three Holladay incorporated method SIA calculators

Postoperative residual astigmatism is one of the unsatisfying visual outcomes of phacoemulsification resulting from surgically induced astigmatism (SIA). Various SIA calculators have been introduced to assist surgeons in calculating SIA for toric intraocular lens (IOL) determination. The aim of this...

Various SIA calculators have been introduced to assist surgeons in calculating SIA for toric intraocular lens (IOL) determination. The aim of this study was to compare SIA values calculated using three different Holladay incorporated method SIA calculators. A data set of 80 eyes from 72 subjects who had undergone uneventful phacoemulsification using less than 3 mm clear corneal incision technique were included in the study. The preoperative and postoperative K-readings were computed into the three online Holladay incorporated method SIA calculators which were the SIA Calculator version 1.1 (SIAC1.1); Single Case SIA Calculator (SCSIAC); and Panacea SIA Calculator version 8(6.0) (Panacea). The mean individual SIA values obtained from each calculator were compared. There were no significant differences in mean individual SIA between the calculators (p > 0.05).

In conclusion, the SIAC1.1, SCSIAC and Panacea produced a comparable SIA value among calculators.
