Long-Term Complications of Extracapsular Cataract Extraction with Posterior Chamber Intraocular Lens Implantation, in Nigeria

AIM: To identify the long-term complications of extracapsular cataract extraction with posterior chamber intraocular lens implantation surgery, in the National Eye Centre, Kaduna, Nigeria. METHODS: The study is a retrospective review of patients that have had extracapsular cataract extraction with posterior chamber intraocular lens implantation, in the National Eye Centre, Kaduna, Nigeria from January 1996 to December 1999. The medical records of all patients that satisfy these criteria were retrieved. Information collected included age, sex, eye operated upon, intra-operative complications, pre-operative visual acuity and last follow-up, and long-term post-operative complications. RESULT: Medical records of only 66 patients (71 eyes) that maintained a minimum follow-up of at least one year were retrievable. No major intra-operative complications were recorded. Only one eye had posterior capsule rent. Ninety percent of the operated eyes had vision of 6/60 or better one year post-operative. The overall visual outcome (WHO criteria) was borderline. Of the corrected eyes, the consultants have a statistically significantly better outcome than residents. The following post-operative complications were recorded in 25 (35.2%) eyes: pseudophakic bullous keratopathy (11.3%); posterior capsular opacification (7.0%); persistent inflammation (7.0%); secondary glaucoma (2.8%); pupil distortion (5.6%); and ocular hypotony (1.4%). CONCLUSION: ECCE + PC-IOL microsurgery is associated with long-term complications like PBK (Pseudophakic bullous keratopathy) and PCO (Posterior capsular opacification). Their management creates new demands in our country. This study is limited by the small number of eyes eligible for review at least one year after surgery.     

Primary Posterior Chamber Intraocular Lens Implantation in Traumatic Cataract With Posterior Capsule Breaks

Background: In patients with incomplete posterior capsule support, posterior chamber intraocular lenses (PC-IOLs) were implanted with both haptics transs-cleral fixation. This causes more damage to the eye and may result in more complications. In patients with small posterior breaks, non-fixation or single haptic fixation may be adequate.Methods: Thirty-two consecutive patients of traumatic cataract with posterior capsule breaks caused by penetrating eye trauma were retrospected. Posterior chamber intraocular lenses were implanted in all these patients with three techniques, ie, without fixation, with single haptic fixation and with both haptics fixation. The selection of the technique was based on the position and size of the posterior capsule. The follow-up period was 21 days to 28 months (mean, 15. 2 months).Results: Intra-operative problems included ciliary body bleeding ( two patients, 6. 25% ) and enlargement of posterior capsule breaks (2 patients, 6. 25%). Postoperative visual acuity was 0. 5 or

A New Posterior Chamber Intraocular Lens Formula for Axial Myopes

The accuracy of prediction of postoperative refractive error was evaluated in 175 patients with extracapsular cataract extraction and a Shearingstyle posterior chamber intraocular lens. The Binkhorst, Colenbrander-Hoffer and SRK formulas were all less accurate in patients with an axial length greater than or equal to 24.5 mm. The standard error of the estimates of the Binkhorst formula was 1.2 diopters, the Colenbrander-Hoffer formula 1.18 diopters and the SRK formula 0.90 diopters. A new intraocular-lens formula for axial myopes was derived by polynomial regression analysis with a standard error of the estimate of 0.85 diopters. This new formula was accurate within 1 diopter in 79% of axial myopes compared to 71 % for the SRK, 66% for the ColenbranderHoffer and 64% for the Binkhorst formulas. Regression analysis of a surgeon's own patient data can further improve the accuracy of prediction of the postoperative refraction.

目的：分析中央孔型有晶状体眼后房型人工晶状体（ICL）植入矫正中低度近视的短期有效性、安全性和稳定性。方法：回顾性队列研究。连续纳入2020年7—12月在成都爱尔眼科医院植入V4c ICL晶状体的低度近视患者490例（707眼）,均完成术后6个月随访,术前及术后1、3、6个月测量裸眼视力、矫正视力、眼压、拱高和角膜内皮细胞计数,并计算手术安全性、有效性、预测性以及稳定性。术前、术后数据采用配对t检验进行统计分析。结果：随访至术后6个月,患者裸眼视力（-0.076±0.079）LogMAR,手术有效性指数为1.26±0.21,最佳矫正视力（-0.079±0.080）LogMAR,安全指数为1.13±0.18。术后屈光度在±0.5 D以内的占比94.9%,可预测性为99.1%;等效球镜度在术后1个月为（-0.063±0.135）D,术后6个月为（-0.071±0.126）D;角膜内皮细胞计数术前（3 078±258）个/mm2,术后6个月为（2 953±206）个/mm2,损失率为（1.05±0.39）%。术后1个月拱高为（498±143）μm,术后6个月为（474±177）μm。ICL更换比例为1.4%。术后未出现严重威胁视力的并发症。结论：ICL 植入术（中央孔型,V4c ICL）矫正中低度近视具备良好的效果,手术安全、可靠,且预测性高,患者视力稳定。     

人工晶体植入术后复视

目的:本文报道7例人工晶体植入术后复视病例,并初步探讨其原因及预防。方法:随访60例单侧白内障摘除及人工晶体植入术连续病例。复视病例,检查复视类型、眼位、眼球活动度、屈光状态、瞳孔及眼底,并散瞳检查人工晶体位置。结果:本文报告白内障摘除及人工晶体植入术后复视发生率为11.67％。术前存在斜视,双眼融合功能障碍,局麻药物对眼外肌的毒性作用,人工晶体中心偏移,黄斑部病变及晶体后囊不均匀混浊等与术后复视有关。结论:复视是白内障摘除及人工晶体植入术后一个重要的并发症。其治疗往往较困难,根据复视的可能原因,采取预防措施对减少术后复视有帮助。眼科学报1997;13:210—212。     

Membrane Formation on the Surface of Implanted Posterior Chamber Intraocular Lenses

Purpose: To study the prevention and treatment of the membrane formation on the lens surface after extracapsular cataract extraction (ECCE) with posterior chamber intraocular lens (PCIOL) implantation.Methods: We reviewed the records of 312 cataractous patients that had undergone ECCE with PCIOL implantation between 1989 and 1993. Postoperatively all pa-tients were examined under slit-lamp microscopy. The membrane formation on the surface of PCIOL in pupilar area was divided into four grades. Two membranes of surgical removal were observed under a transmission electron microscopy. One PCIOL of surgical removal was observed under a scanning electron microscopy.Results: Of 312 patients, 21 had the membrane formation on the surface of the PCIOL postoperatively. The incidence of the membrane formation was 6. 7%. Comparisons with cases of senile cataract showed the incidence to be significantly the highest among; 1. patients who had traumatic cataract (P<0. 05); 2. patients with complicated cataract (P<0. 05
