DEVICE: Norlase LION photocoagulator (05700002165428)

An electrically-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.

An electrically-powered device assembly in which input energy is used to excite a diode to emit a low-power and/or high-power therapeutic laser beam intended for ophthalmic surgery (e.g., ocular incisions, ocular photocoagulation, iridectomy, vitrectomy). Some types may also include an air pump to disperse subretinal fluid in certain procedures (e.g. retinal detachment repair). The laser utilizes a diode/semiconductor chip (as the active medium); it does not include femtosecond pulsing, or fundus imaging technology.
