目的:通过统计分析屈光不正患者总合散光的轴位与角膜散光的轴位的关系和大小,为验光配镜、隐形眼镜的基弧及散光性隐形眼镜的轴位选择、准分子激光的手术量计算提供参考。方法:对107例屈光不正患者,用同一电脑验光仪对其同时、同眼、同状态的情况下作屈光状态的测定及角膜曲率的测定,每人重复3次,通过电脑记录,得出总合散光及角膜散光的轴位,进行统计分析。结果:近视患者的总合散光轴位与角膜散光的轴位的夹角是5.73°±3.97°,混合散光患者的总合散光轴位与角膜散光的轴位夹角为3.13°±2.49°,远视患者的总合散光轴位与角膜散光的轴位夹角为6.35°±4.20°。结论:眼屈光状态中总合散光的轴位与角膜散光的轴位所构成的夹角主要是由于晶体及角膜内表面散光的轴位不一致所引起。眼科学报2000;16:279～280。
OBJECTIVE: To analyze the relationship and size between axial total astigmatism and axial astigmatism in patients with refractive errors, and to select the axial positions of optometric glasses, contact lenses base radiographs and astigmatic contact lenses, and excimer laser The calculation of operation provides a reference. Methods: A total of 107 patients with refractive errors were examined with the same computerized refractometer for the same time, the same eye and the same state, and the refractive status and corneal curvature were measured. Each patient was repeated 3 times and recorded by computer. A total of astigmatism and axial corneal astigmatism, statistical analysis. Results: The angle between the total astigmatism axis and axial corneal astigmatism was 5.73 ° ± 3.97 ° in myopia patients, and the axial angle between total astigmatism axis and corneal astigmatism was 3.13 ° ± 2.49 ° in mixed astigmatism patients. The total axial distance of astigmatism patients with corneal astigmatism axial angle of 6.35 ° ± 4.20 °. CONCLUSIONS: The included angle between axial astigmatism and corneal astigmatism in the refractive state of the eye is mainly due to the inconsistent axial distribution of astigmatism on the inner surface of the lens and the cornea.
