摘　　要：目的分析角膜塑形镜试戴患者的基本情况及相关屈光参数,以期提高试戴成功率,并分析试戴失败原因。方法回顾分析45例(89只眼)进行角膜塑形镜试戴近视眼患者的资料。结果 45例患者中,41例(91.1%)试戴成功,其中37例(82.2%)定制了镜片;4例(8.9%)试戴失败。通过对达到良好适配时的K值与平坦K值比较,得出角膜越平坦,两者的差值越小;而角膜越陡峭,两者的差值越大。4例试戴失败病例中,3例E值较试戴成功者E值明显偏低(P<0.01),1例存在逆规散光。结论严格掌握好角膜塑形镜试戴者入选标准、规范验配流程,才能提高角膜塑形镜试戴成功率。对于E值偏低及存在逆规散光的患者试戴须谨慎。Objective To analyze the basic information and the relative refractive parameters of patients for the improvement of the success rate and the efficiency of trial fitting in orthokeratology and to analyze the cause of failure. Methods Data of 45 myopic children （89 eyes） accepting trial fitting in orthokeratology were analyzed retrospectively. Results There were 41 successful trial fitting cases in which 37 （82.2%） ordered lens and 4 （8.9%） failed. It showed that the flatter the corneal was , the smaller the difference would be by comparing K values in well fitting and flat fitting, and vice versa. E value was obviously lower in the 3 failure cases（P 〈0.01 ） and against-the-rule astigmatism existed in the other failure case. Conclusions The success rate of orthokeratology trim fitting would not be improved until the ad- mittahle standard and trial fitting procedures were controlled strictly. Attention should be paid to the patients whose E value was lower and the existence of against-the-rule astigmatism. （ Chin J Ophthalmol and Otorhinolaryngol, 2010,10 ： 221-223 ）
