Does Laparoscopic Lens Contamination Effect Operative Time? A Study on the Frequency and Duration of Lens Contamination and Commonly Used Measures to Maintain Clear Vision
Objective: To determine factors affecting lens fogging and different methods used for decreasing lens fogging and operation time.
Methods: This cross-sectional study was conducted in General surgery department of Gulab Devi Hospital, Lahore from January 2022 to July 2022.

A total of 288 lens contamination events were observed in all these operations with an average of 4.11 lens contamination events per case. According to study an average, 60.9% of the operational time lens remained clear, 31.2% of the operational time lens remained contaminated and 7.92% of the operative time was spent in cleaning the laparoscope.
