Abstract:

Purpose: To compare the efficacy and visual outcomes of toric intraocular lenses, limbal relaxing incisions and opposite clear corneal incisions for management of coexisting astigmatism on cataract surgery. Patients and Methods: In this retrospective comparative study revealed 56 eyes of 56 patients’ files with visually significant cataract and coexisting corneal astigmatism were undergone phacoemulsification with either Toric IOL or monofocal IOL with LRI or monofocal IOL with OCCI. The main outcome measures were postoperative 6-month best corrected visual acuity, cylindrical and keratometer value changes. Results: Best corrected visual acuities at sixth months were better 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 they became 1.01 ± 0.61, 1.16 ± 1.12 and 0.9 ± 0.8 D postoperatively, respectively. (p<0.01, p<0.01, p<0.01) Corrected astigmatism amount was 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 refractive astigmatism were detected postoperatively in all groups. Although the most prominent improvement in refractive astigmatism occurred in the LRI group, there was no significant difference among the groups.
