AIMS
To assess the long term results of intraocular lens (IOL) implantation for traumatic cataract in young children in a developing country.
METHODS
Prospective hospital based study of 52 children (age 2-10 years) undergoing unilateral cataract extraction and IOL insertion for traumatic cataract performed by a single surgeon in south India. Children were reviewed regularly and followed up initially for 3 years.
RESULTS
There were no serious operative complications. Clinically significant posterior capsule opacification was almost universal (92%) and YAG capsulotomy or membranectomy was performed on 48 eyes. Some degree of pupil capture affected 35% of eyes and was complete in 6%. Visual acuity was 6/12 or better in 67% of eyes at the last follow up examination.
CONCLUSION
The visual acuity results 3 years after implantation of posterior chamber IOLs in older children with traumatic cataracts in south India were encouraging. In developing countries where follow up is unreliable it is essential to plan to clear the axial part of the posterior capsule either at the time of surgery or soon afterwards.
目的
评估在一个发展中国家对幼儿外伤性白内障植入人工晶状体（IOL）的长期效果。
方法
对印度南部一名外科医生为52名（年龄2至10岁）因外伤性白内障接受单侧白内障摘除及人工晶状体植入手术的儿童进行基于医院的前瞻性研究。对儿童进行定期复查，最初随访3年。
结果
无严重手术并发症。临床上显著的后囊膜混浊几乎普遍存在（92%），48只眼进行了YAG激光后囊切开术或膜切除术。一定程度的瞳孔夹持影响了35%的眼睛，6%的眼睛完全受影响。在最后一次随访检查时，67%的眼睛视力达到6/12或更好。
结论
在印度南部，年龄较大的外伤性白内障患儿植入后房型人工晶状体3年后的视力结果令人鼓舞。在随访不可靠的发展中国家，在手术时或术后不久计划清除后囊膜的轴向部分至关重要。
