To evaluate refractive outcomes of toric intraocular lens (IOL) implantation in eyes with previous radial keratotomy (RK).
Toric IOLs were implanted in 72 eyes. The same surgeon performed each operation. The Lenstar LS900 (Haag-Streit AG) was used in this study. Implanted IOLs were either the Alcon lenses (SN6ATx series, Fort Worth, TX, USA) or the Johnson & Johnson Vision lenses (ZCTxxx series, Santa Ana, CA, USA). Vector analysis was performed, and we compared preoperative corneal astigmatism to postoperative refractive astigmatism.
Preoperatively, 1% and 8% of eyes had corneal astigmatism ≤0.5 D and ≤1.0 D, and postoperatively 69% and 83% of eyes had refractive astigmatism ≤0.5 D and ≤1.0 D, respectively (P<0.05). The centroid values were 0.93 D @ 1° ± 2.02 D preoperatively and 0.17 D @ 168° ± 0.68 D postoperatively (P<0.05).
Toric IOLs can be successfully used to treat corneal astigmatism in RK eyes.
