A comparison of visual discomfort experienced by surgeons in wireless versus conventional endoscopy in laparoscopic surgery

BackgroundThis study was performed to introduce a new wireless endoscopic system. Research and development were based on fifth-generation transmission technology. Eye symptoms and visual discomfort induced by the novel endoscopic system were compared with those induced by the conventional endoscopic system before and during laparoscopic pelvic surgery.Materials and methodsTwenty surgeons successfully conducted laparoscopic pelvic surgeries using a conventional endoscopic system and a wireless endoscopic system. Subjective and objective data were measured to evaluate visual discomfort before and 2 hours after surgery.ResultsIn the conventional endoscopic and wireless endoscopic system groups, no significant differences were found in the presurgical or postsurgical questionnaires. In both groups, tear film breakup times significantly decreased after surgery. However, after comparing the 2 groups, no statistically significant difference was found.ConclusionsCompared with the conventional endoscopic system, the novel wireless endoscopic system does not cause additional visual discomfort for experienced surgeons.
