Which practice is NOT a recommended lens fog prevention practice during laparoscopy?

• A. Pre-warming
• B. Using anti-fog agents
• C. Lens irrigation
• D. Ignoring condensation and leaving the lens fogged

Answer: (D)

Clear visualization during laparoscopy hinges on preventing condensation on the camera lens. Fog forms when warm intra-abdominal gas meets the cooler surface of the lens, creating droplets that scatter light and obscure detail. Pre-warming the lens and the system reduces the temperature difference, making condensation less likely. Anti-fog agents alter the lens surface to discourage droplet formation or to spread moisture into a thin, transparent film. Lens irrigation physically clears any condensate that does form, restoring a clear view quickly. Ignoring condensation and leaving the lens fogged would compromise visualization, increasing the risk of errors or injury during the procedure.
