目的 研究青年人晶状体前囊膜弹性 ,以便提高白内障摘出和人工晶状体植入术的成功率.方法 测量 5 3人共 90只尸眼 (平均年龄 2 6 .8a)晶状体前囊膜连续环形撕开口的弹性.结果 前囊膜撕开口弹性为 1.38~ 2 .74,前囊膜撕开口直径越大 ,弹性越大 ;前囊膜弹性与年龄无关.结论 本年龄段内 (19~ 40 a)前囊膜弹性与撕开口直径呈直线正相关.青壮年期白内障术中前囊膜撕开口直径 5 .0~ 5 .5 mm为宜“,”Objective To study the elasticity of the anterior lens capsule in youth in order to increase the successful rate of the cataract extraction and intraocular lens(IOL) implantation.Methods The elasticity of continuous circular capsulorhexis in 90 eyes of 53 youth cadaver were measured (mean age: 26.8 years). Results The elasticity of the tear opening ranged from 1.38 to 2.74. The larger the diameter, the stronger the elasticity. There was no significant correlation between the capsular elasticity and age.Conclusion A Highly significant linear correlation was found between the anterior capsular elasticity and the opening diameter in youth ( age range :19~40 years). It is recommended that the capsular opening diameter be the best from 5.0mm to 5.5mm in youth cataract extraction.
