Purpose: 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. Materials and Methods: 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. Results: 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. Conclusion: 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.
