Materials and Methods: The records of 26 eyes of 18 patients who had cataract, ≥1.0 D corneal astigmatism and undergone uncomplicated phacoemulsification surgery with toric intraocular lens implantation between 2010 and 2012 were retrospectively evaluated. Uncorrected and best corrected visual acuity (logMAR), astigmatism values preoperatively and in the postoperative first, third and sixth month and intraocular lens axis rotation degrees were recorded.
Results: The mean age was 57.8±15.4 (47-78) years. Twelve were women and 6 were men. The mean postoperative follow up period was 4.1±2.3 (1-12) months. Preoperative uncorrected visual acuity was 1.03±0.32 (logMAR) and best corrected visual acuity was 0.48±0.25 (logMAR). In the postoperative first month uncorrected visual acuity was 0.32±0.28 (logMAR) and best corrected visual acuity was 0.18±0.15 (logMAR). The mean cylinder values was -2.94±1.0 D preoperatively and -0.65±0.60 D in the postoperative first month. At last visits the mean best corrected visual acuity was improved to 0.13±0.15 (logMAR) and the mean astigmatism values was -0.79±0.65 D. The mean axis rotation was 6.42±2.45 degree in the first postoperative month.
Conclusion: Toric intraocular lens implantation is an effective safe surgical option in correcting preexisting corneal astigmatism. In our study it is shown that toric intraocular lens implantation reduced astigmatism and improved visual acuity significantly.
