User Manual Q-LAS September 2023 1 Introduction We thank you for having chosen our Q-LAS and wish you every success in using this versatile laser system. The Q-LAS laser generates a laser beam of high intensity, which can cause injuries if handled improperly.
Tissue disruption by plasma shockwave in the human eye. 1.2.2 Medical Purpose The Q-LAS is a medical laser device intended to be used in ophthalmic applications particularly for the treatment of glaucoma (closed angle glaucoma) and posterior cataract opacification (PCO) patients. The Q-switched Nd:YAG laser delivers very short but high energetic laser pulses.
1.4 Theory and Technical Set-up The Q-LAS is a Nd:YAG laser with a wavelength of 1064 nm. The radiation in the laser head is generated with the help of a diode. The laser beam that leaves the device has a small diameter;...
User Manual Q-LAS September 2023 2 Transport and Storage We at A.R.C. Laser GmbH will make sure that the device is packed and transported with the greatest possible care. Before unpacking the laser, please check the packaging for damage and report any damage immediately to the shipping agent and A.R.C.
2.2 Return Shipment The device will be shipped in a specially developed transport packaging. Please keep this. If you ship the device back to A.R.C. Laser GmbH, be sure to use the intended transport packaging. The transport packaging is designed so that the device fits snugly into the foam parts.
Ensure to provide a suitable location for the device before it is set up. The Q-LAS should be operated in an easily accessible place. The laser should not be operated near a heater, since the device only works when the ambient temperature is not higher than 45°C.
User Manual Q-LAS September 2023 3.2.3 Reflecting Surfaces To avoid danger from reflected direct and scattered radiation, there must be no reflective surfaces in the room. These can be: • Mirrors • Pictures behind glass • Chrome surfaces • Windows These surfaces must be removed or suspended or matted.
4 Safety Information 4.1 General The Q-LAS laser is a precision instrument for medical applications. The system has been carefully developed and tested through intensive testing before shipping. In order to offer you and the operating personnel all possible protection, we recommend that you read this section of the operating instructions carefully.
1064 nm may be used. The safety goggles should bear a CE mark as well as the appropriate protection class. The following laser safety goggles from A.R.C. Laser GmbH are suitable for the Q-LAS: • AS01033: Protection class D LB 6 + IR LB8 + M LB8Y / Optical density OD 8+ Safety goggles can be worn even when the person wears glasses.
(full angle) Permitted Maximum Radiation: 2 x 10 4.7 CE-Regulations The laser system Q-LAS has been approved by the notified body in accordance with the European Regulation 2017/745/EU for medical devices. Accordingly, the device bears the CE mark CE 0123.
The stop button is used to switch off the laser in emergencies. To prevent a defect in the unit - caused by the power supply unit - the Q-LAS has two thermal fuses under the table. When the thermal fuses are tripped, they are pushed down and the red LED on the main switch fades out.
Make sure the socket sticks firmly to prevent unexpected system interlock problems. 4.12 Safety Shutter/Aiming Beam The Q-LAS has an internal safety shutter. This safety switch enables the release of the laser beam mechanically. As soon as the laser has passed its internal tests and calibra- tions, the laser can be set to READY mode by pressing the READY button.
September 2023 4.15 Labels and Markings The Q-LAS is provided with various warnings in accordance with European and worldwide guidelines. This is to prevent the laser user from being exposed to laser radiation due to carelessness. Following labels are attached on the Q-LAS: 4.15.1 Type plate...
The “Laser Aperture” label marks the laser output. The other labels provide information about the type and inten- sity of the laser system. 4.15.4 Serial number The Q-LAS consists of several components, each with its own serial number. 4.15.5 Laser STOP This symbol indicates where the laser STOP button is located.
September 2023 Operating Conditions 4.16 The medical laser Q-LAS is not suitable for use in connection with combustible gas mix- tures of all kinds. The device is not approved for operation at altitudes above 2,000 m above sea level. The air pressure must be between 1080 hPa and 750 hPa.
During the briefing, every person working in the vicinity of the laser should be pre- sent. Laser-Safety-Training The Q-LAS laser is designed for medical users. It may only be used by personnel who have been instructed in its operation. A.R.C. Laser GmbH recommends attending additional seminars to train working with dif- ferent laser systems.
*The type of the mains cable depends on the destination country. One cable is included in the standard scope of delivery. **Only chin rest paper provided by A.R.C. laser is allowed to be used with the Cobra. When the enclosed chin rest paper is used up, refills can be obtained from A.R.C. laser.
(ZU11056, diameter 116mm, height 28mm). A T T E N T I O N Only spare parts and applicators which are approved by A.R.C. Laser GmbH are to be used with the device. Accessories that have not been approved can significantly impair the safety and reliability of the device.
User Manual Q-LAS September 2023 5.4.4 Foot Switch (optional) An optional footswitch is available for your Q-LAS. This enables to emit laser radiation via the footswitch. 5.4.5 Lowering prism (optional) A lowering prism can also be installed in the Q-LAS. This enables treatment by lowering the prism, without swinging out the lightning arm.
A T T E N T I O N The Q-Las should not be operated for longer than 5 hours at a time. Restart the laser after 5 hours at the latest so that it can carry out the system check during the start routine. This ensures that undetected errors cannot occur.
The display shows different information depending on the state of the unit. When the Q-LAS is started by turning the key switch, the following sequence occurs: • Warm-up phase: the system counts from 100 to 0. If the system has not yet reached the required operating temperature after the warm-up phase (approx.
User Manual Q-LAS September 2023 6.2.2 Burst Mode (Number of pulses = pulses per shot) The number of pulses can be varied between 1, 2 or 3. The total energy output (mJ) changes depending on the number of pulses. By changing the burst mode, the total energy changes as follows:...
6.2.7 DuoSpot Aiming Beam The Q-LAS is equipped with a DuoSpot aiming beam as standard. The aiming beam is only visible in READY mode or while setting its brightness in STANDBY mode. The two beams intersect in the focal plane to form a single spot. The laser exerts its effect on the focal plane.
User Manual Q-LAS September 2023 6.3 Adjustments at the laser head Power Selection Use the energy knob to increase or decrease the energy emitted during one shot of the laser.
