摘要
目的:我们应用眼前节全景分析仪(Pentacam)测量有晶状体眼后房型人工晶状体(ICL)植入术手术前后前节形态指标,评价有晶状体眼后房型人工晶状体植入术的安全性及稳定性。方法:选取行有晶状体眼后房型人工晶状体植人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。
AIM：To evaluate safety and stability of ICL implantation treatment of high myopia through the observation of anterior segment parameters such as ACD and ICA over time pre-and post-operation changes by Pentacam.
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.
