Clinical Utility of a Novel Minimally Invasive Lens Cleaner.

Abstract

Introduction: Minimally invasive lens cleaning remains a persistent problem. Several internal and external cleaning devices are available, but most products are expensive, interrupt operative flow, require additional materials, or lack universal clinical efficacy. This study evaluates a novel minimally invasive lens cleaner. Methods: Patients undergoing a laparoscopic procedure from April to July 2025 were included. The number of times the laparoscope was removed for cleaning during the operation was measured. The duration of cleaning time was measured also. The cleaning time included removal, cleaning, reinsertion, and resumption of the operation. A control group utilized the Clearify^© while an experimental group utilized the novel device. The mean number of lens cleaning episodes and duration of lens cleaning were compared using a t test between the two groups with a P < .05 as significant. Results: Twenty control and 20 experimental cases were compared, including foregut, biliary, and bariatric procedures. The mean number of cleaning episodes/case for the control group during biliary, bariatric, and foregut procedures was 5.3 ± 1.5, 11.4 ± 6.2, and 11.8 ± 2.7, respectively. The mean number of cleaning episodes/case for the experimental group during bariatric and foregut procedures was .5  ±  0.9 and .3  ± 0 .5, respectively. The mean number of wipes in the foregut and bariatric group was significantly lower for the experimental group (P < .05). The lens cleaner was applicable for 5 mm and 10 mm angled laparoscopes. Longer operations in the control group required more cleaning episodes. However, operative time did not impact the number of cleaning episodes in the experimental group. The mean total time per case in the control group was significantly longer versus the experimental group (P < .05). Conclusion: The novel lens cleaner was clinically efficacious and significantly decreased the number of cleaning episodes. The product provided a clear view of the operative field while enhancing procedural efficiency by decreasing the number of times operative flow was disrupted.
