Ergo loupes enable me to retain an ergonomically healthy posture even in long surgeries – no more bending and straining my neck and upper back! The Butterfly headlight is lightweight and comfortable. It provides excellent lighting for many hours during operations without unnecessary wires or heavy batteries. Today I use my Ergo loupes with the Butterfly headlight for almost every surgery, from complex palate surgeries to routine surgeries such as tonsillectomy and adenoid surgeries.
