The Problem

Surgery's oldest problem.
Finally solved.

For decades, surgeons have relied on a century-old workaround for compromised visibility: removing the laparoscope, wiping the lens, reinserting it mid-procedure. These interruptions contribute to errors, complications and unnecessary burden on surgeons, patients and systems.

No standardised solution has existed, until now.

Technology

Surgical clarity when it matters most

Using advanced temperature controls, a precision burst of fluid, and our patented jet-drying technology, Klens cleans the laparoscopic lens while it remains inside the patient. The procedure continues without interruption

Clinical Data

The evidence is clear

Compromised vision consumes up to 44% of laparoscopic procedure time. In robotic surgery, that figure climbs to 55%. This is a major structural inefficiency in modern surgery.
