目的分析有晶状体眼可植入接触镜(ICL)植入后夜视力障碍的相关的影响因素.方法回顾性分析双眼ICL植入术25例(50只眼).于术后6个月采用问卷调查方式评估夜间视觉障碍的发生率和严重程度.利用单因素和多因素Logisitic回归分析探测术后夜间视力障碍有关的影响因素.角膜屈光力、前房深度、术后残余屈光度、高阶像差,术前和术后的中间视觉瞳孔直径及二者之间的差异,中间视觉瞳孔直径与ICL光学区直径之间的差异,角膜横径、睫状沟水平间距,术后ICL拱高,都作为潜在的影响因素进行分析.另外还包括ICL屈光力、长度、光学区直径和散光度等参数.结果夜间视觉障碍的发生率,光晕为34.00％,眩光为26.00％.认为光晕发生的相关因素有:①与瞳孔直径和植入的ICL光学区直径之间的差异(P=0.013);②角膜横径(P =0.028);③植入ICL光学区直径(P=0.030).并发现植入的ICL散光度是产生眩光的一个重要影响因素(P =0.047).结论在夜间视力障碍的潜在影响因素中,植入的ICL光学区直径、中间视觉瞳孔直径与ICL光学区直径之间的差异及角膜横径可引起光晕,而ICL散光度可导致眩光.

Objective To investigate the influencing factors of night vision disturbances after implantable contact lens implantation.Methods Fifty eyes of 25 patients who underwent implantable contact lens implantation in both eyes were retrospectively reviewed.The incidence and severity of night vision disturbances were evaluated using questionnaires 6 months after surgery.Univariate sample and multiple logistic regression analyses were used to detect influencing factors associated with postoperative night vision disturbances.Potential influencing factors included in the analysis were keratometric value,anterior chamber depth,postoperative residual refractive error,higher-order aberrations,preoperative and postoperative mesopic pupil size,the difference between preoperative and postoperative mesopic pupil size,the difference between mesopic pupil size and implantable contact lens optic zone diameter,corneal transverse diameter,sulcus-to-sulcus diameter,and postoperative implantable contact lens vaulting.The power,size,optic zone diameter,and toridity of the implantable contact lens were also included as variables.Results The incidence of night vision disturbances was 34.00％ for halos and 26.00％ for glare.Halos were found to be significantly related to:(1)The difference between mesopic pupil size and implantable contact lens optic zone diameter (P =0.013);(2) The corneal transverse diameter (P =0.028);(3) The implantable contact lens optic zone diameter (P =0.030).For glare,toricity of the implantable contact lens was revealed as a significant influencing factor (P =0.047).Conclusion Conclusions Possible influencing factors for night vision disturbances include implantable contact lens optic zone diameter,the difference between mesopic pupil size and implantable contact lens optic zone diameter,and the corneal transverse diameter which can cause halos,and the toricity of the implantable contact lens which can cause glare.
