摘要：

We evaluated the centration of excimer laser myopic photorefractive keratectomy by analyzing the corneal topography in 60 eyes of 37 patients. Computer-assisted analysis of corneal topography was performed preoperatively and one week post-operatively. The distance and the direction from the center of the entrance pupil to the center of the ablation was calculated using a personal computer. Downward displacement of the ablation relative to the center of the entrance pupil was observed in 51 eyes (85%). The mean distance of the center of the ablation from the center of the entrance pupil was 0.51 +/- 0.31 mm (range 0.06 mm to 1.64 mm). To achieve more precise centration, we recommend applying an eye-movement tracking system to photorefractive keratectomy.
