摘要
目的 通过对正常成人尸眼晶状体的显微解剖研究 ,推动白内障摘出及人工晶状体 (IOL )植入术的改进。方法 测量 5 3人共 10 2只成年尸眼 (年龄 19～ 41a)的晶状体直径 (L D)及无韧带区直径 (ZFZ)等有关正常值。结果 正常成年人 L D平均为 9.6 1m m,ZFZ为 7.73m m,ZFZ与 L D呈直线正相关关系 ;晶状体核直径 (ND)平均为 7.6 8mm ,核厚度 (NT)为 2 .9m m,同一人的 L D、ND、NT呈直线正相关关系 ;晶状体囊袋直径 (CBD)平均为 10 .15 m m ,与 L D比较有显著差异。结论 成年人白内障摘出术中连续环形撕前囊应在 5～ 6
Objective To study the micro anatomy of the lens of the normal adult cadaver eyes in order to complement the lens micro anatomical theory and improve the cataract extraction and the intraocular lens (IOL) implantation Methods The mean values of the lens diameter (LD) and the zonular free zone diameter (ZFZ) in 102 eyes of 53 cadavers were measured Results The mean LD and ZFZ were 9 61mm,7 73mm respectively The larger the LD,the larger the ZFZ The diameter of the lens nucleus (ND) was 7 68mm, the lens nucleus thickness (NT) was 2 9mm There is a linear positive correlation between the right eye and the left eye of a man The mean capsular bag diameter (CBD) was 10 15mm,larger than LD Conclusion It is recommended that the capsular opening diameter be from 5 to 6mm in adult cataract extraction
