in developing countries congenital cataract has become an important cause of treatable blindness in childhood. However, difficulty in correcting aphakia is one of the reasons for poor visual outcome.
to determine the visual outcome after extra capsular cataract extraction and intra ocular lens implant and factors militating against good visual outcome in children.
a prospective interventional study of cataract extraction in children with intra ocular lens implant. Extra capsular cataract extraction with intra ocular lens implant was performed using the superior limbal approach. Polymethyl Methacrylate lenses were inserted. Posterior capsulotomy was done with a 25G needle bent at the tip in 26 eyes.
thirty two eyes of twenty five children aged between 4 months and 16 years were operated. Extra capsular cataract extraction with posterior chamber intraocular lens implant was done in 27 (83.4%) eyes, plain extra capsular cataract extraction in 3 (9.4%) eyes, extra capsular cataract extraction with anterior chamber intraocular lens implant in 1 (3.1%) eye and vectis extraction in 1 (3.1%) eye. Twenty six eyes had primary posterior capsulotomy. Thirty-two (100%) eyes and 15 (60%) children were blind before surgery. Result of post operative visual acuity in 18 children after refraction was 6/18 or better in 4 (22.2%) children 6/24-6/60 in 11 (61.1%) and< 3/60 in 3 (16.7%) children.
visual rehabilitation following extra capsular cataract extraction with Intra Ocular Lens Implant is encouraging in children.
在发展中国家,先天性白内障已成为儿童可治疗性失明的一个重要原因。然而,无晶状体矫正困难是导致视力预后不佳的原因之一。
确定儿童行白内障囊外摘除及人工晶状体植入术后的视力预后,以及影响儿童获得良好视力预后的因素。
一项对儿童白内障摘除并植入人工晶状体的前瞻性干预性研究。采用上方角膜缘入路行白内障囊外摘除及人工晶状体植入术。植入聚甲基丙烯酸甲酯晶状体。对26只眼使用尖端弯曲的25G针头进行后囊切开术。
对年龄在4个月至16岁之间的25名儿童的32只眼进行了手术。27只眼(83.4%)行白内障囊外摘除联合后房型人工晶状体植入术,3只眼(9.4%)行单纯白内障囊外摘除术,1只眼(3.1%)行白内障囊外摘除联合前房型人工晶状体植入术,1只眼(3.1%)行晶状体钩娩出术。26只眼进行了一期后囊切开术。术前32只眼(100%)及15名儿童(60%)失明。18名儿童验光后的术后视力结果为:4名儿童(22.2%)视力达到6/18或更好,11名儿童(61.1%)视力为6/24 - 6/60,3名儿童(16.7%)视力<3/60。
儿童白内障囊外摘除联合人工晶状体植入术后的视力康复情况令人鼓舞。
