方法：收集在我院植入ICL的高度近视患者15例30眼，年龄20～40(平均28.0)岁，术前屈光度等效球镜度数为-6.50～-22.50(平均-11.05 ±2.50)D。采用光学相干断层扫描仪分别检查术后6mo； 1，2，3a的拱高情况，以及对比敏感度检测仪检查术后1，3a的对比敏感度情况。

结果：患者术后6mo时拱高均值最大，以后每年下降，3a后拱高与术后6mo比较，拱高下降，差异具有统计学意义。对比敏感度术后1a与3a比较差异无统计学意义，并且均位于正常值内。

结论：ICL植入术后拱高随着术后时间的延长而下降，对比敏感度却未见明显改变。二者更长期的改变有待进一步观察。

METHODS: The clinical data of 15 patients(30 eyes)were collected. The patients' average age was 28.0 years(from 20 to 40 years). Preoperative spherical refraction was(-6.50 to -22.50)D(mean -11. 05±2.50)D. The vault was measured with optical coherence topography(OCT), after operation 6mo, 1, 2, 3a; and the contrast sensitivity function was measured with vision testing instrument after operation 1 and 3a.

RESULTS: The results revealed that the vault was decreased after operation 6mo which was the highest. There was statistical difference between 6mo and 3a. While the contrast sensitivity was no statistical difference after operation between 1a and 3a and was all in the normal value.

CONCLUSION: The vault was decreased after ICL implantation in high myopia with years, but the contrast sensitivity was no obvious change. A long-time observation for the vault and contrast sensitivity should be performed.
