We performed a prospective study evaluating the 2-year success rate of extracapsular cataract surgery and posterior chamber IOL insertion performed in 610 eyes by an experienced surgeon in the Nepal Eye Hospital, Kathmandu, Nepal. All patients were followed for 2 years. All eyes underwent manual irrigation and aspiration of cortical materials with the insertion of a modified J-loop posterior chamber IOL. Almost one half of eyes had final uncorrected visual acuities of 20/50 or better. Devastating complications, including retinal detachment, corneal decompensation, and endophthalmitis, occurred in 7 (1.2%) eyes. Extracapsular cataract surgery with IOL implantation appears to be a possible alternative in underdeveloped nations where the prevalence of cataract is high and aphakic spectacles are not easily obtained by poor patients and may be lost or broken. The procedure may improve the quality of vision, and therefore the quality of life, in those patients able to obtain pseudophakic vision.
我们进行了一项前瞻性研究，评估在尼泊尔加德满都尼泊尔眼科医院由一位经验丰富的外科医生对610只眼施行的囊外白内障手术及后房型人工晶状体植入术的2年成功率。所有患者均随访2年。所有术眼均采用改良J袢后房型人工晶状体植入联合手法水分离及皮质吸出术。几乎一半术眼最终裸眼视力达到20/50或更好。7只眼（1.2%）发生了包括视网膜脱离、角膜失代偿和眼内炎等严重并发症。在白内障患病率高且贫困患者不易获得无晶状体眼镜，眼镜还可能丢失或损坏的欠发达国家，囊外白内障摘除联合人工晶状体植入术似乎是一种可行的替代方法。该手术可改善能够获得人工晶状体视力的患者的视觉质量，进而改善其生活质量。
