摘　　要：目的:观察生后3mo内行先天性白内障摘除术,并在眼轴发育至21mm时行二期人工晶状体植入术后6～8岁人工晶状体(IOL)眼患儿眼轴长度的变化。方法:对15例26眼出生后3mo内行白内障摘除联合后囊膜连续环形撕囊及前段玻璃体切割术,并在眼轴发育至21mm(年龄在2周岁左右)时行二期人工晶状体植入术后的患儿进行连续观察。分别在6,7,8岁时测量术眼眼轴长度,另选取年龄和性别相匹配的正常儿童作为对照组,采用横断面病例对照研究比较两组间的差异。结果:各年龄段术后患儿平均眼轴长度分别为23.75±1.40,23.88±1.73,23.91±1.55mm,与对应年龄对照组比较,6岁阶段眼轴发育比正常对照组儿童长,差异有统计学意义(P<0.05),7～8岁阶段与正常对照组无差异(P>0.05)。结论:出生后早期行先天性白内障摘除并在2周岁左右行二期人工晶状体植入术后的人工晶状体眼患儿,在6～8岁阶段,6岁时眼轴发育较同龄正常儿童快,但7～8岁时眼轴发育较同龄正常儿童基本相同。AIM：To observe the axial length in early stage（6-8 years old） after pediatric cataract extraction and intraocular lens implantation.METHODS：A cross section case series of total 15 IOL infants（26 eyes）,who had undergone pediatric cataract extraction,posterior continuous curvilinear capsulorhexis and anterior vitrectomy within 3 months and received intraocular lens implantation till the axial length of 21mm（about 2 years old）.Patients were divided into 3 groups based on their ages at follow-ups：6 years group,7 years group,8 years group.The changes of axial lengths in each group were measured.The changes of axial length were analyzed and compared with those of normal age-gender-matched children.RESULTS：The mean axial length from 6-8 years group was 23.75±1.40,23.88±1.73 and 23.91±1.55mm respectively.Axial length in 6 years group was longer than that in normal control group,the difference was statistically significant（P0.05）,There was no difference between 7-8 years groups and normal control group（P0.05）.CONCLUSION：The axial length of young children,following second term IOL implantation at the age of 6 was longer than that of normal children,but there was little change compared with normal children after the age of 7.
