| description | Purpose The aim of this retrospective study was to compare the accuracy of intraocular lens (IOL) power calculation using the OKULIX ray-tracing software compared with third generation IOL power calculation formulas.
Patients and methods The study included 80 consecutive eyes of 80 patients (26 males and 54 females, with a mean age of 58.8±15.1 years), for whom phacoemulsification and IOL implantation was performed following biometry using the OKULIX ray-tracing software and third-generation IOL power calculation formulas for IOL power calculation. Accuracy of IOL power calculation was investigated by subtracting the attempted and achieved spherical equivalent 1 month postoperatively and was recorded as the mean absolute error.
Results OKULIX ray-tracing software calculated IOL power was 17.1±8.5 diopters (D), which was statistically significantly different from Sanders, Retzlaff, Kraff (SRK)-T, Hoffer Q, SRK II, and Holladay formulas (16.7±8.3, 16.6±8.7, 16.8±8, and 16.7±8.5 D, respectively, P<0.001). The OKULIX ray-tracing software mean absolute error was 0.2±0.2 D, which was statistically significantly less than that of the SRK-T, Hoffer Q, SRK II, and Holladay formulas (0.5±0.5, 0.6±0.5, 0.8±0.7, and 0.6±0.5 D, respectively, P<0.001).
Conclusions The OKULIX ray-tracing software seems to deliver reliable and more accurate results in comparison to the third generation IOL power calculation formulas. |
