Periodically, and at least annually, you should measure the actual power being delivered through your IRIDEX delivery device(s) to verify that the laser system is still operating within factory calibration parameters. Regulatory agencies require that manufacturers of US FDA CDRH Class III and IV and European EN 60825 Class 3 and 4 medical lasers supply their customers with power calibration procedures. Only IRIDEX trained factory or service personnel may adjust the power monitors. TO VERIFY THE POWER CALIBRATION: 1. Make sure all persons in the room are wearing the appropriate laser safety eyewear. 2. Connect a properly functioning IRIDEX delivery device. 3. Set the power to 200 mW. 4. Set the duration to 2000 ms and the interval to one pulse. 5. Center the aiming beam at the middle of the power meter sensor. CAUTION: A spot size of less than 3 mm diameter can damage the power meter sensor. 6. Place the laser in Treat mode. 7. Aim the output beam from the IRIDEX delivery device into the power meter, following the power meter instructions for sampling the laser power. 8. Press the footswitch to deliver the treatment beam. Record the power meter reading in the table below. 9. Set the power to 500 mW. 10. Press the footswitch to deliver the treatment beam, and record the reading. 11. Set the power to 1000 mW. 12. Press the footswitch to deliver the treatment beam, and record the reading. 13. Set the power to 2000 mW. 14. Press the footswitch to deliver the treatment beam, and record the reading. 24 IRIDEX IQ 577™ Operator Manual 15510 Rev A Calibration date for power meter and sensor: __________________________________ Power (mW) Exposure Duration (ms) 200 1000–3000 160–240 500 1000–3000 400–600 1000 1000–3000 800–1200 2000 1000–3000 1600–2400 Date: ___________________ Meter Reading (mW) Acceptable Range (mW) Calibrated by: __________________________ Of: ___________________________________ 15. If the readings fall outside the acceptable levels, check the power meter, ensure that you have accurately placed the beam on the power meter, and check the readings again with another IRIDEX delivery device. 16. If the readings are still outside the acceptable levels, contact your local IRIDEX Technical Support Representative. 17. Place a signed copy of the table in your device records to refer to during use and service. 15510 Rev A Maintenance 25 6 Safety and Compliance To ensure safe operation and prevent hazards and unintended exposure to the laser beams, read and follow these instructions: • To prevent exposure to laser energy, except as a therapeutic application from either direct or diffusely reflected laser beams, always review and observe the safety precautions outlined in the operator manuals before using the device. • This device is intended for use only by a qualified physician. The applicability of the equipment and treatment techniques selected is your sole responsibility. • Do not use any device if you think it is not functioning properly. • Laser beams reflected from specular surfaces can harm your eyes, the patient’s eyes, or others’ eyes. Any mirror or metal object that reflects the laser beam can constitute a reflection hazard. Be sure to remove all reflection hazards near the laser. Use non-reflecting instruments whenever possible. Be careful not to direct the laser beam at unintended objects. CAUTION: Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. Protection for the Physician Eye safety filters protect the physician from backscattered treatment laser light. Integral eye safety filters are permanently installed in the Slit Lamp Adapter, LIO, EasyFit Adapter, IRIDEX Integrated Slit Lamp Workstation, and SL130 Integrated Slit Lamp Workstation. For endophotocoagulation, a separate discrete eye safety filter assembly must be installed into each viewing path of the operating microscope. All eye safety filters have an optical density (OD) at the laser wavelength sufficient to permit long-term viewing of diffuse laser light at Class I levels. When using the dermatology handpieces, always wear the appropriate laser safety eyewear. Always wear appropriate laser safety eye wear when performing or observing laser treatments with the unaided eye. Protection for All Treatment Room Personnel The Laser Safety Officer should determine the need for safety eyewear based on the Maximum Permissible Exposure (MPE), Nominal Ocular Hazard Area (NOHA), and Nominal Ocular Hazard Distance (NOHD) for each of the delivery devices used with the laser system, as well as the configuration of the treatment room. For additional information, refer to ANSI Z136.1, ANSI Z136.3, or European Standard IEC 60825-1. 26 IRIDEX IQ 577™ Operator Manual 15510 Rev A The following formula was used to calculate the worst case NOHD: NOHD = (1.7/NA)(/MPE)0.5 where: NOHD = the distance at which the beam irradiance equals the appropriate corneal MPE NA = the numerical aperture of the beam emerging from the optical fiber = the maximum possible laser power, in watts MPE = the level of laser radiation, in W/cm2, to which a person may be exposed without suffering adverse events Numerical aperture is equal to the sine of the half-angle of the emerging laser beam. Maximum available laser power and associated NA vary with each delivery device, resulting in unique NOHD values for each delivery device. NOTE: Not all delivery devices are available for all laser models. NOHD Range MPE (W/cm2) Numerical Aperture (NA) Maximum Power (W) NOHD (m) Slit Lamp Adapter 2.55 10-3 0.012 2.0 22.38 Laser Indirect Ophthalmoscope (LIO) 2.55 10-3 0.03 2.0 8.95 EndoProbe 2.55 10-3 0.10 2.0 2.69 Delivery Device 15510 Rev A Safety and Compliance 27 Safety Compliance Complies with FDA performance standards for laser products except for deviations pursuant to Laser Notice No. 50, dated June 24, 2007. CE-labeled devices comply with all requirements of the European Medical Device Directive MDD 93/ 42/EE. Feature Function EMERGENCY STOP Immediately disables the laser. Protective housing The external housing prevents unintended access to laser radiation above Class I limits. Safety interlock An electronic interlock at the fiber port prevents laser emission if a delivery device is not properly connected. Remote interlock An external door interlock outlet is provided to disable the laser if the treatment room doors are opened during treatment. An interlock jumper wire is also provided. Keyswitch The system operates only with the proper key. The key cannot be removed while in the On position. Laser emission indicator The yellow Standby light provides a visible warning that laser radiation is accessible. When Treat mode is selected, a three-second delay prevents unintentional laser exposure. The console delivers laser energy only when the footswitch is depressed while in Treat mode. An audible tone indicates that the console is delivering laser energy. The audible indicator volume can be adjusted but not turned off. Beam attenuator An electronic beam attenuator prevents any laser radiation from exiting the console until all requirements for emission are met. Viewing optics Eye safety filters are required when using the laser system. Manual restart If laser emission is interrupted, the system goes into Standby mode, the power drops to zero, and the console must be manually restarted. Internal power monitor Two monitors independently measure the laser power before emission. If the measurements differ significantly, the system enters Call Service mode. Footswitch The laser cannot be placed in Treat mode if the footswitch is damaged or improperly connected. The footswitch can be immersed and cleaned (IPX8 per IEC60529) and is shrouded for safety (ANSI Standard Z136.3, 4.3.1). 28 IRIDEX IQ 577™ Operator Manual 15510 Rev A Labels NOTE: The actual label may vary with laser model.
