Aim: To compare the efficacy and visual outcomes of toric intra-ocular lenses, limbal relaxing incisions and opposite clear corneal incisions for management of coexisting astigmatism in cataract surgery. Methods: In this retrospective comparative study files of 56 pati-ents who underwent phacoemulsification with either Toric IOL or monofocal IOL with LRI or monofocal IOL with OCCI for their 56 eyes with visually significant cataract and coexisting corneal as-tigmatism were investigated. The main outcome measures were postoperative 6-month best corrected visual acuity, changes in cylindrical and keratometer value.Results: Best corrected visual acuities at sixth months were bet-ter at a statistically significant level in three groups compared to the baseline measurements (p<0.01, p<0.01, p<0.01). The mean refractive astigmatism values were preoperatively 2.92±1.1 in the LRI group, 2.46±1.7 in the OCCI group, 2.68±0.90 in the toric group whereas postoperatively they were 1.01±0.61, 1.16±1.12 and 0.9±0.8 D respectively (p<0.01, p<0.01, p<0.01). Corrected degrees of astigmatism were 1.9±1.1 for the LRI group, 1.3±1.2 for the OCCI group and 1.78±0.90 dioptry for the toric group. The difference among three groups was not statistically significant.Conclusion: An increase in the BCVA value and a decrease in ref-ractive astigmatism were detected postoperatively in all groups. Although the most prominent improvement in refractive astig-matism occurred in the LRI group, there was no significant diffe-rence among the groups.
