目的 :探讨角膜曲率计检查在测量角膜散光中的作用。方法 :采用角膜曲率计、散瞳验光、显然验光三种方法对屈光不正患者 2 2 4只眼进行检查。结果 :本组病例中散光度数以 1 0 0D以下为主。散瞳验光和显然验光所测出的散光轴位与角膜曲率计所测出的散光轴位比较 ,差异无显著性 (P >0 0 5)。在散光度数上 ,散瞳验光和显然验光测出的散光度数与角膜曲率计所测出的散光度数比较 ,差异有非常显著性 (P <0 0 1 )。散瞳验光与显然验光之间在散光度数上比较 ,差异无显著性 (P >0 0 5)。结论 :角膜曲率计对于散光轴位的测量在散瞳验光和显然验光中起到重要的辅助作用
Objective: To investigate the role of keratometer in the measurement of corneal astigmatism. Methods: The corneal curvature meter, mydriatic optometry, apparently optometry three methods of amblyopia in patients with 224 eyes were examined. Results: The number of astigmatism in this group of patients to 1 0 0D the following. There was no significant difference in astigmatism axis measured by mydriasis and obvious optometry between astigmatism axis and corneal curvature meter (P> 0.05). In astigmatism, the difference between the astigmatism degree measured by mydriatic optometry and obvious optometry was significantly different from that measured by keratometer (P <0.01). There was no significant difference in the degree of astigmatism between mydriatic optometry and obvious optometry (P> 0.05). CONCLUSIONS: The keratometer’s measurement of axial astigmatism plays an important auxiliary role in mydriatic optometry and apparently optometry
