Perceptions and use of computer-assisted surgery (CAS) in the orbit

Computer-assisted surgery (CAS) is now an established adjunctive tool used by many surgical specialties operating in the head and neck region, including neurosurgery and ENT surgery. It describes a system incorporating hardware and software which allows merging of preoperative or intra-operative patient imaging with three-dimensional localisation of surgical instruments in real time. Despite demonstrated advantages, a central issue regarding acceptance of any new technology, particularly in novel areas, is evidence-based proof of its benefit being superior to current standards. A recent and increasing debate has been the application and utility of CAS in the orbit. The purpose of this survey and study is to question practising oculoplastic and orbital surgeons on their use and perception of this technology for orbital surgery, to better understand its current status and possible future direction. The survey results will be gathered together with data already received from surgeons in Canada and the United States.
