目的：研究青少年近视患者在配戴角膜塑形镜与配戴框架眼镜后各自AC/A的变化情况，并进行对比分析，进一步明确角膜塑形镜与框架眼镜对近视患者视功能的影响，及对青少年近视的控制作用。方法：随机选取60例来我院成功验配角膜塑形镜的青少年近视患者作为试验组，随机选取60例门诊就诊并给予框架眼镜的青少年近视患者作为对照组，观察两组患者屈光矫正前后AC/A及等效球镜度的变化并进行对比研究。随访时间依次为戴镜1，3，6mo；1a。结果：试验组戴镜前和后1，3，6 mo；1 a的AC/A值分别为4．05±2．03，3．05±1．85，3．31±1．02，3．14±1．64，3．20±1.55，戴镜后1，3，6mo；1a与戴镜前比较，差异均有统计学意义（P＜0．05）。对照组戴镜前和后1，3，6mo；1a分别为4．12±1．86，4．09±1．38，3．58±1．45，3．84±1．41，4．23±2.01，戴镜后1，6 mo；1 a与戴镜前比较，差异无统计学意义（P＞0．05），戴镜后3mo与戴镜前比较，有显著差异（ P＜0.05）。两组戴镜前无显著差异（ P＞0．05）；戴镜后1，6mo；1a，两组有显著差异（P＜0．05）；戴镜后3mo两组差异无统计学意义（ P＞0．05）。近视度数增长的观察时间为1a。试验组等效球镜度增加了0．38±0．35DS ，对照组增加了0．84±0．56DS ，两组差异有统计学意义（P＜0．05）。结论：两种矫正方式都能降低高AC/A值，试验组较对照组能更快更好地改善调节与集合的关系，近视度数增长后AC/A值会偏高。角膜塑形镜对中低度近视的矫正有效，它较框架眼镜能更有效地控制青少年近视的增长速度，是目前控制近视的一种有效方法。它对近视患者视功能的改善机制还有待进一步的研究。

AIM: To study the ortho-k lens and frame glasses in patients with juvenile myopia the influence of the accommodative convergence/accommodation ( AC/A ) , further clear the effectiveness of controlling the myopia development and security. METHODS:Randomly select 60 patients to our hospital check-up successfully with ortho-k lens of juvenile myopia patients as experimental group, and 60 cases were randomly selected given frame glasses as control group.we observed two groups of patients before and after refractive correction the changes of AC/A and spherical equivalent.Observation time was 1 month, 3 months, 6 months, 1 year. RESULTS: The AC/A of experimental group worn glasses before and after 1 month, 3 months, 6 months, 1 year were 4.05 ±2.03, 3.05 ±1.85, 3.31 ±1.02, 3.14 ±1.64 and 3.20 ±1.55, respectively with statistically significant difference (P<0.05).That of control group, worn glasses before and after 1 month, 3 months, 6 months, 1 year were:4.12±1.86, 4.09 ±1.38, 3.58 ±1.45, 3.84 ±1.41 and 4.23 ±2.01, respectivley.Worn glasses after 1 month, 6 months, 1 years there were no statistically significant difference ( P>0.05 ).Three months after worn glasses there was significant difference (P<0.05).The two groups had no significant difference before(P>0.05).Wearing glasses after 1 month, 6 months, 12 months, the two groups had significant difference ( P<0.05 ); 3 months after worn glasses there was no statistically significant difference (P>0.05).Spherical equivalent, observation time was 1 year:experimental group spherical equivalent degrees increased by 0.38 ±0.35DS, the control group spherical equivalent degrees increased by 0.84±0.56DS , the two groups were statistically significant difference (P<0.05). CONCLUSION: Both groups could reduce the AC/A value. The experimental group than the control group was better and faster to improve the relationship between the adjustment and collection.The AC/A value was on the high side after myopic degree growth.The ortho-k lens is an effective lens for the moderate myopia .It can more effectively control the growth of juvenile myopia than frame glasses, which is an effective way to control myopia.The mechanism of improving his visual function remains to be further studied.
