To evaluate the results of small-incision manual extracapsular cataract extraction surgery (ECCE) in a district hospital in West Africa.
Margret Marquart Catholic Hospital, Ghana, West Africa.
This prospective study consisted of 200 eyes of 193 patients who had small-incision manual ECCE between January 1999 and May 2000. For comparison, the charts of 32 patients (32 eyes) operated on between July and December 1998 using a limbal incision (control group) were retrospectively analyzed. Outcome measures included intraoperative and postoperative complications, postoperative visual acuity, and refractive astigmatism.
In the small-incision ECCE group, self-sealing wounds were achieved in 129 eyes (64.5%). Vitreous loss occurred in approximately 3% of eyes in both the small-incision and control groups. The final visual acuities were similar between the 2 groups, with more than 90% of eyes in both groups achieving a final best corrected visual acuity of at least 20/60. Eyes in the small-incision group had faster visual recovery (P <.001), a lower incidence of fibrinous iritis (P =.02), and were more likely to have round pupils (P <.001) than eyes in the control group. The main complication of small-incision surgery was moderate corneal edema, which persisted until at least the 1-week visit in 14 eyes (7%). At the most recent visit, 1 eye in the small-incision group (0.5%) had bullous keratopathy.
In a district hospital in West Africa, small-incision manual ECCE surgery yielded faster visual rehabilitation and had a lower incidence of fibrinous iritis than standard ECCE surgery.
评估在西非一家地区医院进行小切口手法白内障囊外摘除术(ECCE)的效果。
西非加纳的玛格丽特·马尔夸特天主教医院。
这项前瞻性研究纳入了1999年1月至2000年5月期间接受小切口手法ECCE的193例患者的200只眼。作为对照,回顾性分析了1998年7月至12月期间采用角膜缘切口手术的32例患者(32只眼)的病历。观察指标包括术中及术后并发症、术后视力和屈光性散光。
在小切口ECCE组中,129只眼(64.5%)实现了自闭式伤口。小切口组和对照组中约3%的眼睛发生了玻璃体脱出。两组的最终视力相似,两组中超过90%的眼睛最终最佳矫正视力至少达到20/60。与对照组相比,小切口组的眼睛视力恢复更快(P<.001),纤维蛋白性虹膜炎的发生率更低(P =.02),且更有可能拥有圆形瞳孔(P<.001)。小切口手术的主要并发症是中度角膜水肿,14只眼(7%)至少持续到术后1周复诊时仍存在。在最近一次复诊时,小切口组有1只眼(0.5%)发生了大泡性角膜病变。
在西非一家地区医院,小切口手法ECCE手术比标准ECCE手术视力恢复更快,纤维蛋白性虹膜炎的发生率更低。
