目的:利用超声生物显微镜(UBM)检测新型中央孔型V4c有晶状体眼后房型人工晶状体( implantable contact lens,ICL) 植入术矫正高度近视术后眼压及眼前节结构形态的变化,以探讨UBM在评价中央孔型V4cICL术有效性及安全性中的作用。方法:选取2015 年 1 月至 2016年 1月在本院行新型中央孔型V4cICL手术患者18例(36眼),均于术前及术后3月、6月、1年利用超声生物显微镜(UBM) 检查①中央前房深度(Anterior chamber depth ACD);②ICL后表面到晶状体前表面的距离(ICL-vault);③房角开放距离(AOD500)在上、下、鼻、颞四个方向上的变化;④小梁虹膜夹角(AIT)在上、下、鼻、颞四个方向上的变化;⑤晶状体中央厚度。结果:术后中央前房深度较术前明显变浅,术后各期间无统计学差异。ICL-vault术后各期间无统计学差异。术后上方、下方、鼻侧、颞侧4个方向的AOD500均较术前明显变浅,术后各期间无统计学差异。术后上方、下方、鼻侧、颞侧4个方向的AIT均较术前明显变浅,术后各期间无统计学差异。术前及术后晶状体中央厚度无统计学差异。术前及术后眼压无统计学差异。结论:新型中央孔型V4cICL在眼内位置稳定,术后眼前节结构稳定,无进行性改变,眼压无持续升高,是安全有效的矫正近视的手术方法。UBM对于ICL术后安全性的评价,具有简便、安全、可重复性好的优点,是理想的客观检查方法。 |

ABSTRACT Objective Detecting the changes of intraocular pressure (IOP) and the shape of the anterior segment after implantation with implantable contact lens (ICL) using ultrasound biomicroscopy(UBM) to explore the efficacy and safety of central pore type V4cICL in correcting the high myopia. Methods From January 2015 to January 2016, 18 patients (36 eyes) underwent a new type of Central V4cICL operation in our hospital. UBM was used, preoperatively and 3, 6, 12 months postoperatively, to detect the Anterior chamber depth, ICL-vault, AOD500 and AIT in 4 angles from upper, lower, nasal and temporal side, and central lens thickness. Results Significant difference was found in Anterior chamber depth after surgery comparing to those in preoperative group and no significant difference was found between any postoperative groups. There was no significant difference in postoperative ICL-vault values. Significant difference was found of AOD500 and AIT in 4 angles from upper, lower, nasal and temporal side and no significant difference was found between any postoperative groups. No significant difference in ICL distance from the anterior surface of the lens and intraocular pressure was found between these groups. Conclusion The lens using new type of central pore type V4cICL surgery was stable in the intraocular position. No significant changes were found in the anterior segment and intraocular pressure after operation. Central pore V4cICL surgery was safe and effective way for correcting high myopia. UBM was an effective, simple and reproductive way to safely evaluate ICL surgery, which can be considered as an ideal method in clinical trials. |
