方法：选取行有晶状体眼后房型人工晶状体植入术治疗的高度近视患者48例90眼，术后随访6mo。Pentacam眼前节全景分析仪测量各时间点的中央前房深度(ACD)、3：00位前房角(ICA)、角膜像差(CA)、角膜曲率(K)和角膜厚度(CCT)等指标。使用SPSS 19.0统计软件，描述术前术后各指标的分布特征，采用配对t检验对各指标进行手术前后的差异性比较。

结果：所有观察指标各时间点均呈正态分布。ACD、3：00位ICA较术前降低(P<0.05)。CA中，总像差(CTA)及低阶像差(CLOA)较术前无统计差异(P>0.05)，高阶像差(CHOA)则较术前有所增加(P<0.05)； K略有减小(P<0.05)。CCT较术前比较均无统计学差异(P>0.05)。对于术后有统计学意义变化的指标，均在术后1mo时即达到稳定状态。

结论：应用眼前节全景分析仪(Pentacam)观察有晶状体眼后房型人工晶状体植入术眼前节形态的变化主要有ICA变窄，ACD变小，CHOA增加，K减小，尚在安全范围内，6mo随访中各值均保持稳定，未出现并发症，但远期效果需进一步随访观察。

METHODS:According to the proposed inclusion criteria, 90 eyes(48 patients)with high myopia who accepted ICL implantation treatment were selected. The mean follow-ups are 6 months. Anterior segment parameters such as ACD, ICA(3'clock), corneal aberration(CA), K-value and CCT were measured by Pentacam at pre- and postoperative different follow-up time points. Using SPSS 19.0 statistical software to describe the indexes distribution at different time points. We compared changes by matching t-test between preoperation and postoperation.

RESULTS:The indexes presented normal distribution. During the follow-ups of all the patients, ACD and ICA(3'clock)were lower than before. Differences were all statistically significant(P<0.05). About CA, CTA and CLOA had no significant difference between preoperative and postoperative(P>0.05); but CHOA increases statistically significant(P<0.05). K-value slightly reduces, Differences are all statistically significant(P<0.05). CCT had no significant difference(P>0.05). For the indexes with statistically significant difference, they achieved stable state in postoperative 1-month.

CONCLUSION:After ICL implantation treatment of high myopia,changes mainly include the ICA and ACD decrease, CHOA increases, K decreases by Pentacam observation,and it is within the scope of the security,all the values are stable during the follow-ups, no complications occur, but the long-term effect need further follow-ups.
