Sterilisation and disinfection constitute the most significant aspect of operation room infection control. The ultrasonic sterilisers which are routinely used for cleaning ophthalmic surgical instruments utilise RO water for the same. Ultrasonic machines should be emptied, disinfected, rinsed, and dried daily. The machine has an outlet connected to a pipe which is used for draining the water after each use. One of the common issues encountered with its use was water splashing and leaking around making the surroundings messy and wet. An innovative simple solution was introduced where a 3 way valve is attached to the outlet. This very economical and easily available valve helps in controlled outflow of the water from the machine thus ensuring complete drainage and thereby eliminating chances for possible contamination.damage to the bulbs without compromising on the illumination.
