Background: To evaluate topography-guided transepithelial ablation in the treatment of high astigmatic eyes (> 3 diopters).
Material and Methods: Retrospective study of 71 eyes of 56 patients three and twelve months after surgery using a 1KHz excimer laser. Pre- and postoperative visual and refractive data as well as post-operative haze were analysed.
Results: The mean pre-operative astigmatism was 3.65 diopters (D) with a range of 3.0 to 6.0. Uncorrected distant visual acuity after three and twelve months were ≥ 20/20 in 63%, respectively 76% of the eyes. Postoperative astigmatism was within ± 0.5 D in 76%, within ± 1.0 D in 92% of eyes after twelve months. No eyes lost ≥ 2 lines of corrected distant visual acuity and 4% of eyes formed haze.
Conclusions: One-step transepithelial topography-guided treatment for high regular astigmatism provided predictable and stable results.
