摘  要:目的对有晶状体眼后房型人工晶状体(PPC-ICL)植入术后患者应用三维眼前节全景分析仪(Pentacam)与前节光学相干断层扫描仪(AS-OCT)测量拱高及其他眼前节参数,分析2种仪器的差异性和一致性。方法横断面研究。连续选取50例(100眼)PPC—ICL植入术术后复查患者,分别应用Pentacam和前节OCT测量眼前节参数。采用配对样本t检验及Bland-Ahman图法对二者差异性和一致性进行统计学分析。结果Pentacam测得拱高值为(353.8±124.0)μm,前节OCT测得拱高值为(536.2±150.8)μm,两者差异有统计学意义(t=27.92,P〈0.05),两者呈高度正相关性(r=0.905,P〈0.05),Pentacam测得拱高比前节OCT测得拱高低(182.4±65.3)μm,其差值95%一致性区间为54.3~310.5μm。结论Pentacam与前节OCT均能为我们提供拱高值,Pentacam测量值显著低于前节OCT测量值,在临床工作中应该综合分析。Objective To compare vault and other biometric measurements obtained after Collamer lens (PPC-ICL) implantation using a Pentacam anterior segment system and an anterior segment optical coherence tomography system (AS-OCT). Methods In this cross-sectional study, vault and other biometrie were was measured in 100 eyes of 50 patients after Collamer lens (PPC-ICL) implantation using a Pentaeam and AS-OCT. The statisitical significance of the difference between the measurements was evaluated by a paired t-test and consistency was assessed by Bland-Altman analysis. Results The mean vault measured by Pentacam and AS-OCT was 353.8±124.0 μm and 536.2±150.8 μm (t= 27.92, P〈0.05) with a significant positive relationship (r=0.905, P〈0.05). There was a 95% level of consistent interval for the difference in interval width (54.3-310.5 μm). Conclusion The measurements obtaind by Pentaeam was much lower than AS-OCT. The difference between the measurements of the vault obtained by the two instruments should be considered and accurately evaluated.
