A mains electricity (AC-powered), head-worn, ophthalmic device used for the stereoscopic examination and laser treatment of the eye, particularly the retina. It typically consists of a headband, a built-in light with aperture control for adjustment of the illumination field, convergence controls to synchronize the illumination and examination beams, a delivery mirror, filters to protect the surgeon against incidental laser-beam reflection, and a power-supply cable for the lighting, and a fibreoptic cable to convey the laser beam. This device is connected to an appropriate laser for delivery of laser energy.
