What are the domestic and international EMC (electromagnetic compatibility) standards for ophthalmic laser therapy devices?

Ophthalmic laser treatment devices (e.g., for posterior capsulitis, glaucoma, and refractive surgery) must comply with GB 9706.1, YY 0505 (domestic), and IEC 60601-1-2 (international) EMC standards. Their core is the generation and control of high-energy laser pulses (e.g., Nd:YAG, femtosecond, excimer lasers). The standards require that transient electromagnetic pulses generated by the laser power supply (especially high-voltage charging and pulse-forming networks) do not affect the precise aiming optical path (e.g., slit lamp) and control system, and that the equipment not interfere with other equipment (e.g., microscopes, camera systems) in the operating room environment. Laser safety and EMC must be considered simultaneously.
