Dr. Mezrich joins Dr. Geeta Lal to discusses the issues with current lighting options in the OR and how they prompted his interest in inventing a new one
Sound Familiar?
My neck hurts after surgery and my headlight strap gives me a headache.
I never seem to be able to get enough light where I need it.
It took me years to master operating with a headlight and I still don't like it.
My colleague wears the light and when he moves his head, I am left in the dark.

By replacing your headlight with a MezLight, you are free to move your head, look away, and reposition yourself without disturbing the position of your lighting. No more holding your neck at an unnatural angle, just to keep enough light on the procedure area.

Your light.
The patented MezLight is autoclavable, allowing your hands to control your lighting without grabbing a towel, scrubbing out or asking for help. The adjustable arm is flexible enough to position your light source exactly where you need it and is sturdy enough to stay there.
Face shield friendly.
Headlights are difficult if not impossible to wear with a face shield. MezLight is not attached to your head, giving you the ideal lighting solution to pair with face shields.
Bright and adjustable.
• LED brightness equivalent to headlight
• 3 brightness settings
• Larger spot size than a headlight
MezLight is Your Light!
Bright, sterile, flexible.
What are surgeons saying about the MezLight?

"The MezLight was easy for the team to setup and simple enough for anyone to use."
-Dr. Michael Nabozny (U. of Rochester Medical Center)
