The Laser Imaging Workstation (LIWS) is a new tool expected to provide the Ophthalmologists with improved laser delivery and digital imaging of the retina. It is an integrated system which allows the physicians to combine diagnosis, treatment planning and laser delivery into one device with one information media common to all three treatment phases. In addition of being one common machine for all three treatment phases, LIWS will be a significantly more precise laser delivery system and can eliminate or significantly reduce the need for patient cooperation, retro bulbar anesthesia and delays due to film processing. Due to a new technology, statistical target tracking, the instrument continuously measures the degree of optical alignment of the patient's eye with the instrument. If this measurement indicates too much misalignment, the surgical laser will be shut down at once and, therefore, LIWS provides also a safe way of doing photocoagulation.
