有晶状体眼后房型人工晶状体拱高相关因素分析

目的 研究分析有晶状体眼后房型人工晶状体(implantable contactlens,ICL)拱高的相关性栽因素.方法 回顾性分析42例(77只眼)已行ICL矫正近视手术患者,屈光度-5.0～-23.0DS,在手术后6个月应用Oculus公司PentacamHR三维眼前节分析诊断系统进行ICL与透明晶状体的间隙即拱高(vault)的检查,并对vault进行相关性分析,统计方法 采用逐步回归的方法 进行多元分析.结果 术后6个月vault平均(452±216.38)μm.vault的多元回归分析相关性依次为ICL长度(回归系数B=0.040,P=0.000),白到白距离(B=-0.231,P=0.011),前房深度(B=0.138,P=0.048).结论 白到白距离较大和前房较深的病人,相对选择的ICL长度较大,得到的vault也较大,ICL与晶状体接触的机会就会降低.

Abstract：

Objective To evaluate the factor affecting vault after implantable collamer lens (ICL) implantation. Methods Retrospective research. All 77 eyes of 42 patients with myopic refractive errors of-5.00 to -23.00 dioptors undergoing ICL implantation were examined. The magnitude of the central vault of the ICL was assessed quantitatively using pentacam HR at 6 months after surgery. Multiple regression analysis was used to assess the factors affecting the amount of vault. Results The mean central vault at 6 months after surgery was 452± 216.38?m. Explanatory variables relevant to the vault were, in order of influence, the ICL length (regression coefficient B =0.040, P =0.000), the horizontal white to white distance (B =0.231, P =0.011) and anterior chamber depth, ACD (B =0.138, P=0.048). Conclusions A high white to white distances and ACD result long ICL, which is likely to render a high vault.
