To describe a modified manual cataract extraction technique, sutureless large-incision manual cataract extraction (SLIMCE), and to report its clinical outcomes.
Case notes of 50 consecutive patients with cataract surgery performed using the SLIMCE technique were retrospectively reviewed. Clinical outcomes 3 months after surgery were analyzed, including postoperative uncorrected visual acuity, best-corrected visual acuity, intraoperative and postoperative complications, endothelial cell loss, and surgically induced astigmatism using the vector analysis method.
At the 3-month follow-up, all 50 patients had postoperative best-corrected visual acuity of at least 20/60, and 37 patients (74%) had visual acuity of at least 20/30. Uncorrected visual acuity was at least 20/68 in 28 patients (56%) and was between 20/80 and 20/200 in 22 patients (44%). No significant intraoperative complications were encountered, and sutureless wounds were achieved in all but 2 patients. At the 3-month follow-up, endothelial cell loss was 3.9%, and the mean surgically induced astigmatism was 0.69 diopter.
SLIMCE is a safe and effective manual cataract extraction technique with low rates of surgically induced astigmatism and endothelial cell loss. In view of its low cost, SLIMCE may have a potential role in reducing cataract blindness in developing countries.
描述一种改良的手动白内障摘除技术,即无缝线大切口手动白内障摘除术(SLIMCE),并报告其临床结果。
回顾性分析连续50例采用SLIMCE技术行白内障手术患者的病历。分析术后3个月的临床结果,包括术后未矫正视力、最佳矫正视力、术中及术后并发症、内皮细胞丢失情况,以及采用矢量分析方法测量的手术源性散光。
在3个月的随访中,所有50例患者术后最佳矫正视力均至少达到20/60,37例(74%)患者视力至少达到20/30。28例(56%)患者未矫正视力至少为20/68,22例(44%)患者未矫正视力在20/80至20/200之间。术中未出现明显并发症,除2例患者外均实现了无缝线伤口。在3个月的随访中,内皮细胞丢失率为3.9%,手术源性散光平均为0.69屈光度。
SLIMCE是一种安全有效的手动白内障摘除技术,手术源性散光和内皮细胞丢失率低。鉴于其成本低廉,SLIMCE在发展中国家减少白内障致盲方面可能具有潜在作用。
