In an Operation Theater, the last thing on a surgeon’s mind is light. But what could be much more important than how well a surgeon can see to do his/her job without any interruption and stress on their eyes.
The best surgical light provides two things - the correct amount of illumination for the procedure and the right patches size.
Brighter does not mean better. Too much [intensity] can fatigue the surgeon’s eyes and cause glare.
With advent of technology and innovation, surgical lighting today is light years ahead of what it was 20 or even 10 years ago. No longer is a light just a light; now they’re interconnected systems which can provide imaging and control for today and future with features that can adjust multiple devices in the room, and video routing systems built for video imaging.
In the operating room, the biggest aid a surgeon can have is to use
High-intensity light without glare and shadow
Light intensity is measured in units called lux. Surgical lights typically are 80,000 to 160,000 lux. "Surgeons’ eyes need to see structures and deep into cavities. In surgical sites, light is absorbed because tissues are dark and non-reflective. For this reason, it’s very important for surgical lights to provide intense light without glare and shadowing, which can contribute to the surgeon’s eye fatigue.
Surgical lighting that could redistribute light as per need
This becomes important as a surgeon may need light in deep-set body openings all the time. Even if all the LEDs are not in use, the light field should remain constant and almost shadow-free. In this scenario, a design wherein the arrangement of LEDs illuminate exactly the same area as all LEDs together can create a difference. So even if LED beams come up against obstacles in the way like people or objects, enough other beams do their job and the surgeon’s view remains unimpaired.
Shadow reduction technology through the utilization of lens reduces the obstructions such as a surgeon’s head automatically as compared to other technologies that require constant focusing by adjusting or pin-pointing the light at a point.
