Abstract

Purpose: To determine the accuracy of intraocular lens (IOL) power calculation with the SRK/T formula in phacoemulsification. Methods: Retrospective review of 119 patients treated with phacoemulsification in 1999 in a University Hospital. Patients with incomplete charts and with intraoperative complications were excluded from this study. Eighty-one patients were selected to establish the accuracy of the SRK/T formula to predict the postoperative refractive error after phacoemulsification and intraocular lens implantation. All biometries were performed by the same technician using the same equipment. All procedures were performed by third-year residents. Results: Comparing the final refraction planned by the surgeon, based on biometry with the SRK/T formula, and the postoperative spherical equivalent, patients were divided in to 4 groups: Group 1 - patients with refractive errors up to ± 0.50 diopters (n=33 (40.7 %)). Group 2 - patients with refractive errors between ±0.51 and ±1.25 diopters (n=29 (35.7 %)). Group 3 - patients with refractive errors between ±1.26 and ±2.00 diopters (n=8 (9.87%)). Group 4 - patients with refractive errors above ±2.01 diopters (n=11 (13.5%)). Conclusions: The postoperative refractive results were satisfactory, the majority of patients (n=62 (76.4%)) presented residual refractive errors after phacoemulsification up to ±1.25 diopters.
