KS—X型丙烯酸酯预装式人工晶状体植入临床分析

Clinical investigation on KS-X acrylic preloaded intraocular lens implantation

目的 评价KS-X型丙烯酸酯预装式人工晶状体植入术的安全性、有效性.方法 对92例（100只眼）老年性白内障患者行超声乳化白内障摘除术,采用预装式推注器植入KS-X型丙烯酸酯人工晶状体.观察患者术后视力、超声乳化时间、人工晶状体植入时间、角膜内皮细胞丢失率、散光变化及手术并发症.结果 术后1周、1月、3月裸眼视力≥0.5的患者所占比例分别为91%,94%,97%;术后3个月矫正视力≥0.8为84%.超声乳化时间为（26.45±13.95）s,平均超声能量为（12.71±8.21）%,人工晶状体植入时间（12.31±3.41）s.角膜内皮细胞丢失率为1 1.92%,术后1周、1月、3月的手术源性散光分别为（1.14±0.29）D、（0.89±0.31）D、（0.76±0.36）D.所有患者均手术顺利,未出现术中并发症.结论 KS-X型丙烯酸酯预装式人工晶状体植入术是安全有效的,其植入过程具有简单、快速、安全、清洁的优点,值得推广.

Objective To evaluate the safety and effectiveness of KS-X acrylic preloaded intraocular lens implantation. Methods 92 patients （100eyes） with age-related cataract were performed with phacoemulsification and KS-X acrylic preloaded intraocular lens implantation. The visual acuity, phacoemulsification time,lens implantation time, the endothelial cell loss percentage, astigmatism and operative complications were observed. Results The visual acuity equal or better than 0.5 were 91%, 94% and 97% one day, one month and three month after surgery respectively. The best corrected visual acuity equal or better than 0.8 three month after surgery was 84%. The phacoemulsification time was 26.45± 13.95sec and mean phacoemulsification energy was 12.71 ± 8.21%. The lens implantation time was 12.31±3.41 sec. The endothelial cell loss percentage was 11.92% one month after surgery. The surgery induced astigmatism were 1.14± 0.29D, 0.89± 0.31 D and 0.76± 0.36 D one week, one month and three month after surgery respectively. There was no operative complication during surgery. Conclusions The KS-X acrylic preloaded intraocular lens implantation are safe and effective. The preloaded injector system is simple, quick, safe and clean.
