A report by the World Health Organization was intended to identify the consequences of impaired vision during laparoscopic surgery. It is emphasized that impaired vision can contribute to surgical errors such as the use of a device incorrectly or displacement of the instruments on structures other than those intended. Moreover, it is reported an increase in the operative time associated with suboptimal view. Finally, the psychological dimension on the disruption of the surgeon is raised with a risk of difficulty of the procedure. To minimize these problems anti mist vision solutions combined with condensed water vapor spray system are among others marketed in recent years.
