To assess the visual outcome of manual small-incision cataract surgery (MSICS) as well as safety, cost, and time of the procedure.
A retrospective study involving candidates for cataract surgery with baseline-corrected distance visual acuity (CDVA) ≤20/120. Visual acuity (VA) was the primary outcome measure while surgical complications, cost, and time of surgery were the secondary outcome measures. Follow-up visits were scheduled at 1 day, 1 week, 1 month, and at 6 and 12 months following surgery.
The study enrolled 3007 patients with a mean age of 66.45 ± 17.3 years. Out of 3007 patients, 2774 (92.2%) were legally blind before surgery (CDVA <20/200) which was significantly reduced to 55 patients (1.9%) by 1 month following surgery. Uncorrected distance visual acuity was 20/60 or better in 2098 eyes (69.8%) at 1 month, in 2035 eyes (67.7%) at 6 months, and in 2017 eyes (67.1%) at 12 months. The posterior capsular rupture was the most common intraoperative complication. Corneal edema was the most common immediate postoperative complication while the development of posterior capsular opacification was the leading cause for later impaired VA. The mean cost was approximately equivalent to 20 US dollars. The median duration of surgery was 10 min.
MSICS is a safe, cost-effective, and time-saving technique for improving the vision of cataract patients in areas with high cataract surgery volume and limited facilities.
评估手法小切口白内障手术（MSICS）的视觉效果以及该手术的安全性、成本和时间。
一项回顾性研究，纳入基线矫正远视力（CDVA）≤20/120的白内障手术候选患者。视力（VA）是主要结局指标，而手术并发症、成本和手术时间是次要结局指标。术后1天、1周、1个月以及6个月和12个月安排随访。
该研究纳入3007例患者，平均年龄66.45±17.3岁。在3007例患者中，2774例（92.2%）术前法定失明（CDVA<20/200），术后1个月时显著降至55例（1.9%）。术后1个月时，2098只眼（69.8%）的未矫正远视力为20/60或更好，6个月时为2035只眼（67.7%），12个月时为2017只眼（67.1%）。后囊膜破裂是最常见的术中并发症。角膜水肿是最常见的术后即刻并发症，而后囊膜混浊的发生是后期视力受损的主要原因。平均成本约相当于20美元。手术中位时长为10分钟。
对于白内障手术量大且设施有限地区的白内障患者，手法小切口白内障手术是一种安全、经济高效且节省时间的改善视力的技术。
