A training course for cataract surgery with intraocular lens implantation was organised in April 1997 at the National Eye Centre, Kaduna, Nigeria. Operations were performed by six Nigerian consultant ophthalmologists under the supervision of two surgeons from Aravind Eye Hospital, India.
A total of 175 eyes with uncomplicated cataracts were operated on after careful selection. All but six patients had extracapsular cataract extraction with posterior chamber intraocular lens insertion during the training programme.
The mean age of the patients at operation was 54. 2 years. One hundred and forty five of the operated eyes (85.8%) were blind before surgery of which six (3.6%) remained blind postoperatively. An uncorrected visual acuity of 6/60 or better was achieved in 87.3% eyes after surgery. Forty one patients (24.3%) were blind before surgery, two of whom (1.2%) remained blind afterwards. The most common intraoperative complication was posterior capsular rent which occurred in 10 eyes (5.7%); striate keratopathy/corneal oedema and cortical remnant were the most common immediate postoperative complications, occurring in 44.6% and 8.0%, respectively.
With adequate surgical skills, extracapsular cataract extraction with posterior chamber intraocular lens implantation offers good visual rehabilitation even under training conditions.
1997年4月在尼日利亚卡杜纳的国家眼科中心组织了一期白内障摘除及人工晶状体植入手术培训课程。手术由6位尼日利亚眼科顾问医师在印度阿拉文眼科医院两名外科医生的监督下进行。
经仔细挑选,共对175只单纯性白内障眼进行了手术。在培训项目期间,除6例患者外,所有患者均接受了白内障囊外摘除及后房型人工晶状体植入术。
手术患者的平均年龄为54.2岁。145只手术眼(85.8%)术前失明,其中6只(3.6%)术后仍失明。术后87.3%的术眼裸眼视力达到6/60或更好。41例患者(24.3%)术前失明,其中2例(1.2%)术后仍失明。最常见的术中并发症是后囊膜破裂,发生于10只眼(5.7%);条纹状角膜病变/角膜水肿和皮质残留分别是最常见的术后即刻并发症,发生率分别为44.6%和8.0%。
即使在培训条件下,具备足够的手术技能,白内障囊外摘除及后房型人工晶状体植入术也能提供良好的视力康复效果。
