PURPOSE
To compare the safety and efficacy between femtosecond laser-assisted cataract surgery using the Victus laser system and conventional cataract surgery.
SETTING
Department of Ophthalmology, Kepler University Hospital, Linz, Austria.
DESIGN
Prospective randomized case series.
METHODS
Both eyes of patients with age-related cataract were randomized to conventional cataract surgery or femtosecond laser-assisted cataract surgery, both with intraocular lens (IOL) implantation. Postoperative follow-up was at 1 day, 1 week, 1 month, 3 months, and 6 months and comprised corrected distance visual acuity, endothelial cell density (ECD), central corneal thickness (CCT), and central retinal thickness. The main outcomes were intraoperative and postoperative complications and the effective phacoemulsification time (EPT). Intraocular lens and capsulotomy centration were evaluated using retroillumination slitlamp photography.
RESULTS
The study enrolled 50 patients. No intraoperative complications occurred in either group. The ECD, CCT, and central retinal thickness were similar between the groups at all follow-up examinations (P > .05). The EPT was not statistically significantly different between the groups (P = .22). The IOL centration was similar between the groups (P = .93).
CONCLUSION
Femtosecond laser-assisted and conventional cataract surgery using the mentioned system were equally safe and effective.
目的
比较 Victus 激光系统辅助的飞秒激光白内障手术与传统白内障手术的安全性和疗效。
地点
奥地利林茨凯普勒大学医院眼科。
设计
前瞻性随机病例系列。
方法
将年龄相关性白内障患者的双眼随机分为常规白内障手术或飞秒激光辅助白内障手术组，均行人工晶状体（IOL）植入术。术后随访 1 天、1 周、1 个月、3 个月和 6 个月，包括矫正远视力、内皮细胞密度（ECD）、中央角膜厚度（CCT）和中心视网膜厚度。主要结局为术中及术后并发症和有效超声乳化时间（EPT）。使用后照法裂隙灯摄影评估人工晶状体和囊袋切开术的中心定位。
结果
该研究纳入了 50 名患者。两组均未发生术中并发症。两组在所有随访检查中 ECD、CCT 和中心视网膜厚度均相似（P>.05）。两组间 EPT 无统计学差异（P=.22）。两组间 IOL 中心定位相似（P=.93）。
结论
使用该系统的飞秒激光辅助白内障手术与传统白内障手术同样安全有效。
