Methods: A total of 366 eyes with keratoconus were subjected to wear proper RGPCL. Keratometer and corneal topography were used to determine the central cornea astigmatism, apex K value, apex decenteation distance, SRI and SAI before, 12 and 18 months after wearing RGPCL.

对圆锥角膜患者选配合适的高透氧RGPCL，分别于配戴前及配戴后12、18个月行角膜曲率计和角膜地形图检查，采集角膜中央散光值、锥顶K值、锥顶偏心距离、SRI、SAI等参数，进行统计学分析。

Objective To evaluate the agreement of measuring corneal power and astigmatism axis between automatic keratometry and corneal topography on ametropia' children.

Methods Keratometric reading with Topcon KR-8100 automatic keratometry and comeal topography with the TMS-4 on 53 ametropia' children, 106 eyes were compared. Difference in measurements of steep meridian power magnitude Ks, flat meridian power magnitude Kf, astigmatism magnitude Ks-Kf and location as well between the two methods were assessed using paired t test.Bland-Altmann method was used to evaluate the agreement of the two methods.

采用KR-8100自动角膜曲率计及TMS-4角膜地形图仪对53例（106只眼）屈光不正儿童进行测量，应用配对t检验对两种方法测量的陡峭子午线角膜屈光力、平坦子午线角膜屈光力、角膜散光Ks-Kf大小及轴向进行比较，并应用Bland-Altmann分析对两种测量方法进行一致性评价。

Glasses used in vision correction have myopia and hyperopia glasses glasses, presbyopic glasses, as well as four glasses astigmatism.

矫正视力用的眼镜有近视眼镜和远视眼镜、老花眼镜以及散光眼镜四种。

This article summarized the influence factor of ametropia after PKP and the main treating methods, including wearing on the glasses or adhesive glasses, taking out stitches of cornea selectly, loose the cut, etc.
