Abstract

PURPOSE
To evaluate the reflection rate of the first eye in order to minimize the real refractive error in the second eye in bilateral consecutive cataract surgeries.
METHODS
A retrospective analysis was performed with 248 patients who underwent bilateral sequential uncomplicated phacoemulsification and posterior chamber intraocular lens implantation. Predicted spherical equivalent was compared with postoperative spherical equivalent, and the range of real refractive error was analyzed by calculating the reflection rate of the first eye.
RESULTS
When the difference between predicted spherical equivalent and postoperative spherical equivalent was greater than 0.5 D as calculated with the formula of Sanders-Retzlaff-Kraff Theoretical (SRK)-T and SRK II, application of 50-60%, 40-50% of the difference of the first eye was high probability to reduce the second-eye real refractive error (75%, 100%).
CONCLUSIONS
Application of 40-60% of the real refractive error in the first-eye can minimize the real refractive error in the second-eye in bilateral sequential cataract surgeries.
