RESUMO
The laser photocoagulation is now treatment of choice for various retinovascular disorders. Conventional slit-lamp based laser delivery systems have many limitations including, questionable accuracy, need of contact lens with local anesthesia, and inadvertent damage to fovea. Navigated laser system, a fundus camera based laser delivery system with computer based laser planning and laser treatment without contact lens achieves improved patient compliance, improved accuracy, and treatment ease for the physician, efficient panretinal photocoagulation pattern laser, excellent documentation, and advanced laser training. This article compares navigated laser systems with available conventional and PASCAL laser systems based on the literature and personal experience of the authors
