This prospective study was conducted at Khyber Teaching Hospital Peshawar, North West Frontier Province (NWFP) of Pakistan over the period of 16 months. It was to assess the demographic pattern, mode of presentation, treatment modalities and postoperative result of aphakic retinal detachment. This study also compared the incidence of aphakic retinal detachment in intracapsular versus extracapsular cataract extraction as well as the duration between cataract surgery and retinal detachment.
A total of 50 patients were recruited in this prospective study. A Proforma was specially designed for this purpose. Detailed history with reference to age, sex, presenting complaints, spectacle wear, previous ocular surgery, duration of surgery/laser treatment, systemic and family history was taken. All patients had detailed ophthalmic examination, underwent conventional retinal reattachment surgery, and were followed up for 6 months.
Of the total number studied, 86% of the patients were males; only 14% were females, with a mean age of 58 years. The overall anatomical success was achieved in 40 (80%) eyes. The visual acuity of 6/12 and better was achieved in 8 (16%) eyes. 20 (40%) eyes attained a vision of 6/18 to 6/36. 12 (24%) eyes had a vision between 6/60 to CF 3m. The vision could not be improved beyond CF 3m in 10 (20%) eyes.
Vitreous loss during cataract surgery is the most common cause of aphakic retinal detachment. The risk is maximal in the first and second year. The overall anatomical attachment achieved through conventional retinal detachment surgery is 80%.
这项前瞻性研究在巴基斯坦西北边境省白沙瓦的开伯尔教学医院进行，为期16个月。旨在评估无晶状体性视网膜脱离的人口统计学模式、就诊方式、治疗方法及术后结果。本研究还比较了囊内与囊外白内障摘除术中无晶状体性视网膜脱离的发生率，以及白内障手术与视网膜脱离之间的间隔时间。
本前瞻性研究共纳入50例患者。为此专门设计了一份表格。详细记录了患者的年龄、性别、就诊主诉、眼镜佩戴情况、既往眼部手术史、手术/激光治疗时长、全身及家族病史。所有患者均接受了详细的眼科检查，接受了传统的视网膜复位手术，并随访6个月。
在所有研究患者中，86%为男性，仅14%为女性，平均年龄58岁。40只（80%）眼睛实现了总体解剖复位成功。8只（16%）眼睛视力达到6/12及以上。20只（40%）眼睛视力达到6/18至6/36。12只（24%）眼睛视力在6/60至CF 3m之间。10只（20%）眼睛视力无法提高到超过CF 3m。
白内障手术中玻璃体丢失是无晶状体性视网膜脱离最常见的原因。风险在第一年和第二年最高。通过传统视网膜脱离手术实现的总体解剖复位率为80%。
