摘要 【目的】探讨配戴角膜塑形镜后角膜塑形效应与近视矫正量之间的关系。【方法】选取2014年1月至2018年1月本院收治的近视患者500例,均配戴角膜塑形镜。检测戴镜前和戴镜7 d、3个月、6个月后角膜塑形效应(眼球屈光度、角膜中央厚度、角膜曲率)、裸眼视力,并分析角膜塑形效应与近视矫正量的关系。【结果】近视患者戴镜7 d、3个月、6个月后眼球屈光度、角膜中央厚度、角膜曲率明显低于戴镜前,裸眼视力明显高于戴镜前(P<0.05);戴镜后3个月、6个月各指标比较,差异无统计学意义(P>0.05);Pearson相关性分析结果显示,眼球屈光度、角膜中央厚度、角膜曲率下降值与裸眼视力升高值呈正相关(P<0.05)。【结论】近视患者配戴角膜塑形镜后角膜塑形效应与近视矫正量有关,眼球屈光度、角膜中央厚度、角膜曲率等可作为评估患者角膜塑形效果的重要指标。

Abstract：【Objective】 To explore the relationship between corneal shaping effect and the amount of myopia correction after wearing corneal plasticizer. 【Methods】A total of 500 cases of myopia were selected from January 2014 to January 2018 in our Hospital. Corneal plastic effects (ocular refraction, central corneal thickness, corneal curvature) and naked eye vision were measured before and after wearing glasses for 7 days, 3 months and 6 months. The relationship between corneal shaping effect and myopia correction was analyzed. 【Results】After 7 days, 3 months and 6 months of wearing glasses, the diopter, central corneal thickness and corneal curvature of myopia patients were significantly lower than those before wearing glasses. The visual acuity of naked eye was significantly higher than that before wearing glasses(P<0.05). There was no significant difference between the indexes of 3 months and 6 months after wearing glasses (P>0.05). Pearson correlation analysis showed that ocular diopter, central corneal thickness and corneal curvature were positively correlated with the increase of visual acuity of naked eye (P<0.05). 【Conclusion】The corneal shaping effect of myopic patients after orthokeratology is related to the amount of myopia correction. Eye refraction/diopter, central corneal thickness and corneal curvature can be used as important indicators to evaluate the effect of corneal shaping.
