Section 886.5305 - Electromechanical tear stimulator(a)Identification. An electromechanical tear stimulator is a non-implantable device intended to increase tear production via mechanical stimulation.(b)Classification. Class II (special controls). The special controls for this device are:(1) Clinical performance testing under anticipated conditions of use must evaluate tear production and all adverse events, including tissue damage, pain, headache, and discomfort.(2) Non-clinical performance testing must demonstrate that the device performs as intended under anticipated conditions of use. The following must be conducted: (i) An assessment of mechanical output specifications, including vibration amplitude and frequency, pressure and force, and acoustic (noise level) properties;(ii) Mechanical safety testing to validate safeguards related to the pressure aspects of the device; and(3) Performance data must demonstrate the electrical safety, thermal safety, and electromagnetic compatibility (EMC) of all electrical components of the device.(4) All patient-contacting components of the device must be demonstrated to be biocompatible.(5) Software verification, validation, and hazard analysis must be performed.(6) Physician and patient labeling must include:(i) A detailed summary of the device's technical parameters;(ii) Instructions for use, including an explanation of all user-interface components and information regarding proper device placement;(iii) Information related to electromagnetic compatibility classification;(iv) Instructions on how to clean and maintain the device;(v) A summary of the clinical performance testing conducted with the device;(vi) Language to direct end users to contact the device manufacturer and MedWatch if they experience any adverse events with this device; and(vii) Information on how the device operates and the typical sensations experienced during treatment. 87 FR 9243 , Feb. 18, 2022
