目的：分析高度近视患者行有晶状体眼后房型人工晶状体(ICL)植入术后拱高变化的影响因素。

方法：回顾性分析2016-01/2017-07我院收治的行ICL植入术治疗高度近视的患者27例54眼的临床资料，术后1、12mo通过Pentacam三维眼前节分析系统检查拱高，并分析角膜白到白距离(WTW)、ICL长度、ICL度数、等效球镜度对拱高变化的影响。

结果：本组患者ICL植入术后12mo拱高显著低于术后1mo(509.47±163.82μm vs 582.45±173.18μm，t=2.099，P<0.05)。ICL长度、ICL度数及术前等效球镜度均是影响高度近视患者ICL植入术后拱高的独立因素(P<0.05)； ICL长度、术前WTW是影响高度近视患者术后拱高变化量的独立因素(P<0.05)。

结论：高度近视行ICL植入术后12mo内拱高呈降低趋势，ICL长度及术前WTW对拱高变化量存在显著影响，ICL长度、ICL度数及术前等效球镜度对拱高存在显著影响。

METHODS: The clinical data of 27 patients(54 eyes)with high myopia were recievd ICL implantation in our hospital from January 2016 to July 2017 were retrospectively analyzed, the vault was examined by Pentacam scheimpflug system at 1mo and 12mo after operation. The effects of white to white distance, ICL length, ICL degree, equivalent spherical mirror degree(spherical equivalent, SE)and pupil diameter on the change of arch height were analyzed by multiple linear regression analysis.

RESULTS: One month after ICL implantation, the vault was 582.45±173.18μm, 12mo after the operation, the vault was 509.47±163.82μm, 12mo after operation was significantly lower than that of 1mo after the operation, the difference was statistically significant(t=2.099, P<0.05); The results of multivariate linear regression analysis showed that the length of ICL, the degree of ICL and the equivalent spherical lenses were independent factors affecting the arch height at 1mo and 12mo after ICU implantation in high myopia patients(P<0.05); The length of ICL and the white to white distance of cornea(WTW)were factors that were significantly associated with a decrease in the vault(P<0.05).

CONCLUSION: The vault was reduced in 12mo after ICL implantation, and the length of ICL and WTW had a significant influence decrease in the vault. The length of ICL, the degree of ICL and the degree of the equivalent sphere had a significant influence on the vault.
