The Coherent Medical Lasers 7900YAG is a Q-switched Nd:YAG ophthalmic laser system operating at 1064 nm, designed primarily for posterior capsulotomy (PCO treatment) and peripheral iridotomy procedures. The system integrates a slit-lamp delivery platform with a binocular microscope head, a dedicated "7900YAG" laser module mounted above the oculars, and a separate desktop control console displaying energy in millijoules, shot count, and operational mode (Laser Ready, Standby, Test Fire, Aiming, Reset) — all clearly visible in the photos. The unit ships complete with a motorized height-adjustable ophthalmic table (rolling base, foot-pedal height control), a foot-operated firing switch, and the control console; the Q-switched pulse mode enables precise photodisruption with minimal collateral tissue damage at clinically programmable energy levels typically ranging from 0.1 to 10 mJ per pulse. This is a used, fair-condition unit; the control panel display is active and reads "STANDBY — 0 SHOTS," indicating the system powers on, though clinical verification and biomedical servicing are required before patient use.
