To evaluate the procedural experience and complications of a novel integrated laser delivery system (NAVILAS(®); OD-OS Teltow, Germany) that combines automated laser delivery with color fundus photography, fluorescein angiography (FA), fundus autofluorescence (FAF) and infrared imaging with a frequency doubled YAG laser.
This prospective study evaluated surgical experience with the NAVILAS automated photocoagulation system for the treatment of patients with diabetic macular edema (DME). Subjective assessment of the accuracy of laser spot placement and postoperative complications were documented.
Twelve patients (7 males, 5 females) were enrolled in this pilot study. Five patients were phakic and 7 were pseudophakic. Image overlays and the tracking system allowed accurate delivery of laser spots of varying size, duration and power. None of the patients reported any pain and tolerated the procedure well. No complications were reported in the study.
In this pilot study, the NAVILAS system allowed accurate laser spot placement with no complications in patients with DME. However a larger sample with longer follow up is required to determine the safety of this procedure.
评估一种新型集成激光输送系统（NAVILAS(®)；德国特尔托夫OD-OS公司）的操作经验和并发症，该系统将自动激光输送与彩色眼底摄影、荧光素血管造影（FA）、眼底自发荧光（FAF）以及倍频YAG激光的红外成像相结合。
这项前瞻性研究评估了NAVILAS自动光凝系统治疗糖尿病性黄斑水肿（DME）患者的手术经验。记录了对激光光斑放置准确性的主观评估和术后并发症情况。
12例患者（7例男性，5例女性）纳入该初步研究。5例为有晶状体眼，7例为人工晶状体眼。图像叠加和跟踪系统能够准确输送不同大小、持续时间和功率的激光光斑。所有患者均未报告任何疼痛，对该操作耐受性良好。研究中未报告任何并发症。
在这项初步研究中，NAVILAS系统能够在DME患者中准确放置激光光斑且无并发症。然而，需要更大样本量和更长随访时间来确定该操作的安全性。
