Original Study


Objectives The aim of this study was to evaluate the astigmatic correcting effect of paired opposite clear corneal incisions (OCCIs) on steep axis in cataract patients with preoperative regular astigmatism undergoing phacoemulsification. Background Phacoemulsification in the era of refractive surgery is hitting new frontiers through the correction of preoperative astigmatism at the same time of cataract surgery. Materials and methods A total of 80 eyes of 80 patients were enrolled in this prospective study. All eyes had cataract, which necessitated undergoing phacoemulsification. Each patient underwent phacoemulsification surgery combined with OCCIs, to correct preoperative astigmatism. All patients were scheduled to postoperative visits at 1 week, 1, 2, and 3 months postoperatively. Corneal topography was performed at each visit. Results Our patients revealed a decrease in preoperative astigmatism throughout the follow-up period. The decrease in the mean astigmatism values was 1.56 ± 0.73 D. This was a statistically significant result (P < 0.05). However, the decrease was most evident in patients with vertical or oblique axes astigmatism, and least evident in patients with horizontal axis astigmatism. Conclusion OCCIs are innovative on-axis technique for correcting astigmatism at the time of cataract surgery. This is advantageous due to the simplicity of the technique and nearly avoidable complications.
