目的：研究眼前节光学相干断层扫描(AS-OCT)所测量的晶状体矢高(CLR)与眼前节参数的关系，及CLR对有晶状体眼后房型人工晶状体植入术(PPC-ICL)术后拱高的影响。

方法：本次研究为回顾性研究。选取2017-07/2018-07在安徽医科大学第二附属医院眼科行PPC-ICL患者40例80眼，采用超声生物显微镜测量眼的水平睫状沟直径(hSTS)及晶状体曲率(LC)，Pentacam眼前节分析仪测量水平白到白直径(hWTW)、前房深度(ACD)及术后拱高。AS-OCT测量CLR和水平径线的两虹膜角膜夹角连线(ATA)。

结果：CLR与ACD(r=-0.706，P<0.01)、术后1a的拱高(r=-0.509， P<0.01)负相关，CLR与LC正相关(r=0.667， P<0.01)，与hWTW(r=0.123， P=0.275)、ATA(r=0.208， P=0.065)、hSTS(r=0.147， P=0.194)无相关性，而ACD与术后1a拱高有正相关性(r=0.680， P<0.01)。

结论：CLR与ACD、LC有明显相关性，对PPC-ICL术后拱高的预测有一定作用。

METHODS:The study included 80 eyes of 40 patients who underwent PPC-ICL implantation at the Department of Ophthalmology, the Second Affiliated Hospital of Anhui Medical University, from July 2017 to July 2018, to measure the sulcus-to-sulcus(hSTS)distance of the eyes using a Compact Touch STS ultrasound biomicroscope and lens curvature(LC), Pentacam was used to measure horizontal-white-to-white(hWTW), anterior chamber depth(ACD)and the vault one year after the operation. Moreover, AS-OCT was used to measure the CLR and horizontal iridocorneal angle-to-iridocorneal angle diameter(ATA).

RESULTS:CLR was negatively correlated with ACD(r= -0.706, P<0.01)and vault one year after the operation(r= -0.509, P<0.01); however, it was positively correlated with LC(r=0.667, P<0.01). There was no correlation between CLR and hWTW(r=0.123, P=0.275), ATA(r=0.208, P=0.065)and hSTS(r=0.147, P=0.194). One year after the operation, there was a positive correlation between the vault and ACD(r=0.680, P<0.01).

CONCLUSION:CLR has obvious correlation with ACD and LC, arch height after PPC-ICL and has a specific effect on the prediction of the vault after PPC-ICL implantation.
