%X stigmatism correction in cataract surgery with Rayner toric intraocular lenses Original Research (4628) Total Article Views Authors: Sally L Painter, Kikkeri S Arun, Jonathan K Kam, et al. Published Date September 2010 Volume 2010:2 Pages 79 - 84 DOI: http://dx.doi.org/10.2147/OPTO.S11821 Sally L Painter, Kikkeri S Arun, Jonathan K Kam, CK Patel Oxford Eye Hospital, John Radcliffe Hospital, Headley Way, Headington, Oxford, United Kingdom Background: Cataract surgery is increasingly regarded as a refractive procedure. Corneal astigmatism can be reduced by the insertion of a toric intraocular lens (T-IOL). Rayner T-flex T-IOLs are licensed for the correction of astigmatism. Methods: In this retrospective study, 46 eyes from 34 patients, in whom T-IOLs were inserted, have been examined. Astigmatism was analyzed using power vectors. Results: Postoperatively, 72% had unaided vision of 6/9 or better, with 42% having <0.25 diopters (D) of residual cylinder and 78% having <1.5 D of residual cylinder, compared with 6.9% preoperatively. Once astigmatism had been converted to power vectors, J0 (measure of astigmatism with an axis of 0¡ã) reduced in magnitude from -0.81 D ¡À 0.85 to 0.09 D ¡À 0.42 (P < 0.001). Conclusion: Rayner T-flex lenses can be reliably used to correct corneal astigmatism.
