目的 :了解斜视术后眼球屈光状态的动态变化及不同术式对屈光状态的影响 ,并对其发生机理进行初步探讨。方法 :用散瞳验光和角膜地形图检查 ,对 6 6例水平斜视患者手术前后屈光状态进行动态分析。结果 :各组的角膜曲率及dk值均差异有显著性 (P <0 .0 5) ,散光组与非散光组dk值变化平均值比较 ,差异有显著性 (P <0 .0 1)。Ⅱ ,Ⅲ 和 Ⅳ 组球镜屈光度术后差异有显著性 (P <0 .0 5) ,Ⅱ ,Ⅲ 和 Ⅳ 组柱镜屈光度术后差异有显著性 (P <0 .0 1)。结论 :水平斜视手术对眼球屈光状态的改变主要是对角膜的影响 ,且是可恢复的 ,不同术式所需恢复时间不同
OBJECTIVE: To understand the dynamic changes of refractive status and the effects of different surgical procedures on refractive status after strabismus surgery, and to investigate its mechanism. Methods: Mydriatic optometry and corneal topography were used to analyze the refractive status of 6 6 patients with horizontal strabismus before and after surgery. Results: There was significant difference in corneal curvature and dk between the two groups (P <0.05). There was a significant difference (P <0.01) between the changes of dk in astigmatism group and non-astigmatism group. There was significant difference (P <0.05) in postoperative diopter in group Ⅱ, Ⅲ and Ⅳ (P <0.05), while there was significant difference in group Ⅱ, Ⅲ and Ⅳ in postoperative diopters (P <0.01). Conclusion: The changes of refractive status of the eyes in horizontal strabismus surgery mainly affect the cornea, and are recoverable. The recovery time of different surgical procedures is different
