目的 探讨一岁内发现白内障并接受手术的无晶体眼儿童的屈光发育规律,为临床无晶体眼的屈光矫正时机选择提供依据.方法 回顾分析58例108眼(单眼8例)一岁内白内障摘除术后无晶体眼儿童,3岁前的阶段性屈光检测结果.其中男性45例83眼,女性14例26眼.平均手术年龄(5.28±3.07)月.屈光检测时段为生后3月、6月、9月、12月、18月、24月、30月、36月.结果 在以上时段检测的患儿无晶体眼的屈光度(等效球镜度)显示,3年里等效球镜度平均降低5.007 D;其中第一年平均降低2.550 D,第二年平均降低1.654 D,第三年降低0.873 D.患儿第12个月,第24个月以及第36个月屈光度差异有统计学意义(P＜0.01).结论 无晶体眼儿童屈光度在生后第一年降低最大,前三年降低幅度呈平稳趋势.较正常儿童明显增大.1岁半前需至少每3个月重新进行屈光度检查.1岁半后至少每6个月重新进行屈光度检查.%Objective To evaluate the refractive status in infants who underwent cataract surgery before one year old.Methods:Refraction examination was preformed in 58 aphakia children (108 eyes,unilateral aphakia 8 eyes),who underwent binocular or unilateral cataract surgery before one year old,in their age of 3 months,6 months,9 months,12 months 18 months,24 months,30 months and 36 months.45 male (83 eyes) and 14 female (26 eyes) were included.The mean age at the time of cataract surgery was 5.28 months.Results:The average reduction of refraction in first 3 years is 5.007D.The mean reduction in the first year is 2.550D,in the second year is 1.654D,and in the third year is 0.873D,the difftrences among each year were statistically significant (P ＜0.01).Conclusion:The refraction of aphakia children is reduced the most in the first year.The annual reductions are more than that in normal children in the first three years.
