摘　　要：目的 回顾性分析和比较儿童白内障（外伤性和先天性）超声乳化术后人工晶状体眼眼轴长度的变化.方法 对30例（30只眼）曾行白内障超声乳化人工晶状体植入术的患儿进行同顾性分析.根据白内障类型将患儿分为2组：外伤性和单侧先天性白内障组.根据患儿年龄分为＜4岁组、≥4岁组和≥7岁组.手术年龄2至10岁,随访测量眼轴长度,计算眼轴年变化率进行比较.结果 14例单侧先天性白内障患儿和16例外伤性白内障患儿的术眼眼轴长度变化比对侧非术眼明显,差异有统计学意义,而单侧先天性白内障和外伤性白内障术眼眼轴长度变化率差异无统计学意义.年龄越小,术眼眼轴长度变化率越大,随年龄增长（≥7岁）,眼轴长度变化越小.结论 儿童人工晶状体眼的眼轴长度增长幅度要比他们非手术眼大,病因对眼轴长度的变化无影响,年龄是影响眼轴变化的重要因素.Objective To analyze and compare the changes of axis in children cataract （congenital and traumatic） after phacoemulsification and intraocular lens implantation retrospectively. Methods The patients were comparatively investigated by dividing them into two groups： traumatic and unilateral congenital,corresponding to the types of their cataract. The ages received phacoemulsification and intraocular lens implantation were 2-10 years old. During the following-up persistent observation, their axial lengths were measured and the variance ratios were calculated, with the method of classifying the patients by their age into： 〈4 years,〉7 years, and ages betweens. Results It was fount out that the variance ratio of axial lengths of 14 cases in unilateral congenital cataract and 16 cases of traumatic cataract were significantly different. Contrarily, nearly no change was found between the variance ration of axial lengths in their un-operated eyes. It also noticed that the variance ratio gradually decrease with higher age, especially for patients elder than 7 years. Conclusions The increase of axial lengths with intraocular lens implanted is much more obvious for the operated eyes than those non-operated ones. The age, instead of the etiology, has the major influence on the change of their axial lengths.
