Introduction
1.
INTRODUCTION Intended Use: The ALLEGRETTO WAVE EYE-Q is a scanning-spot excimer laser system used in refractive surgery for LASIK (Laser In-Situ Keratomileusis) treatments. The uniqueness of the system consists in a combination of technologically refined features, including a compact excimer laser with leading edge high pulse frequency, a galvanometer scanner for positioning the laser spot and a fast eyetracker for determining eye position and laser-beam direction. The Gaussian-shaped beam profile of the individual pulses and an ablation diameter of approximately 1 mm assure the desired contour and minimize surface irregularities during ablation. In addition to the photorefractive Wavefront Optimized applications (myopia with or without astigmatism, hyperopia with or without astigmatism), this attribute in combination with the open system concept enables also the usage of patient related, individual corrections. These corrections could e.g. be based on topography or wavefront data. A further advantage of the small spot diameter is that the ALLEGRETTO WAVE EYE-Q requires the use of only minimal pulse energy. The result is a compact excimer laser beam source with minimal gas volume and minimal gas consumption. As the excimer laser is operated at a high repetition frequency, short treatment times are assured. The integrated eyetracker offers unique automatic centering of the ablation and tracking of even rapid eye movements. With the ALLEGRETTO WAVE EYE-Q the user is provided with a medical device featuring maximum control and safety thus offering the patient highest customer satisfaction.

Safety Instructions 3.1.
Eye Protection Due to the high energy density levels (Fluence) involved, the eye is especially at risk of injury from laser beams. The eye can incur injury even at low levels of irradiation. Protection from laser irradiation has two components: 1. Protection of the patient through the proper operation of the laser device by the physician and 2. Protection of all involved persons, including the physician, from unintended beam emissions.
CAUTION Protective goggles must be worn while in the laser area. Not observance can lead to irreversible eye injury. Make sure that the laser protection goggles are in perfect condition before use! The protective glasses must not show any signs of mechanical damage. The below prescribed type has to be used.
The protective goggles for use with the ALLEGRETTO WAVE EYE-Q laser system must meet the following minimum standards:
IR 193 nm L3 (according to DIN EN 207) Type of Laser IR = Impulse Laser Wavelength at which the Protective goggles offer Protection. Protection Grade
For the purpose of safety verification, the protective goggles must be marked as indicated above.
CAUTION Never look directly at the laser beam.

Safety Instructions 3.2.
Safety Against Fluorine and Ozone When contemplating the potential risk from toxic gases you have to consider Fluorine. Fluorine:
WARNING The ALLEGRETTO WAVE EYE-Q is outfitted with a filter system, which prevents toxic gas from passing out. In case gas odor (fluorine) is detected, the following steps must be taken: • Close the ArF-Premix-gas cylinder valve. • Open all windows in the vicinity of the laser in order to ensure adequate ventilation and - if available - switch on room ventilation, given that the ventilation does not spread the gas in other rooms. • Leave the room and lock the door so that nobody can enter the room. • Call your WaveLight AG authorized service technician or local distributor. The ALLEGRETTO WAVE EYE-Q checks for system gas leaks as soon as it is turned on. The following precautionary measures should be taken when the machine is turned off: • Keep the ArF-Premix-gas cylinders closed when the machine is turned off. • Follow the system instructions when changing the gas, i.e., whenever opening and closing the ArF-Premix-gas cylinders.
Fluorine is part of the “Premix” gas mixture necessary for running the excimer laser. Fluorine is an extremely reactive and highly toxic gas that can cause serious chemical and toxic irritations. It can even, in sufficiently high concentrations, lead to death due to respiratory failure. It distinguishes itself through an extremely piercing odor that can be detected by nose at a concentration below that of the maximum permissible workplace concentration of 0.1 ppm. In case the Premix is inadvertently released into the room air, the user must avoid exposure for periods longer than those permitted according to local safety regulations. A further potential chemical hazard occurs in the formation of hydrofluoric acid, which occurs if the fluorine comes into contact with water. Ozone: A further potential danger consists in the formation of ozone, which arises from the interaction of oxygen and either ultraviolet radiation or high voltage. Ozone can also be detected by its pungent odor and is not critical at concentrations of < 0.1 ppm. Purging the beam path with Nitrogen-gas (N2) reduces the formation of ozone in the laser system.

Safety Instructions 3.3.
Patient Safety In case of evident signs of erroneous data or system malfunction no treatments must be carried out to avoid irreversible injuries to the patient. The ALLEGRETTO WAVE EYE-Q laser system and accessories may only be operated by persons who have been trained in its use and are capable of ensuring proper operation. Precautionary measures are to be taken in the handling and use of all accessories, disposable articles and agents that come into contact with the patient so that exposure to pathogens can be avoided (see chapter 7 “Care Of Device And Accessories” from page 188). After turning on the ALLEGRETTO WAVE EYE-Q carefully go through the System Check procedure and note the results in the Archive Folder (see chapter 5.4 “System Check” from page 42 and chapter 5.17 “Routine Test Procedures With The Control Systems” from page 152). Consult your nearest authorized WaveLight AG dealer or the ALLEGRETTO WAVE EYE-Q service center in case you have any questions regarding this matter. Follow carefully the system comments displayed on the LCD and notebook screen. Pay careful attention especially to messages informing you about laser pulse energy settings and the amount of gas in the cylinders. Consult your nearest authorized WaveLight AG dealer or the ALLEGRETTO WAVE EYE-Q service center in case you have any questions regarding this matter. Make sure that the entered patient and treatment data coincide with the correct eye of the patient. Also be sure that the correct Vertex Distance is entered in the “Setup Menu” of the ALLEGRETTO WAVE EYE-Q. The user is responsible for validating and cross checking of the data during the steps between measurement and treatment. Please perform and note carefully all diagnostic and other clinical findings of the patient's eye prior to the laser treatment. Especially crosscheck the subjective refraction data with the data displayed on the ALLEGRO Analyzer, ALLEGRO Topolyzer, ALLEGRO Oculyzer as well as on the F-CAT System software. This data must not differ significantly. Also check differences between maximum ablation depths between Wavefront Optimized, PTK, A-CAT, Topo-guided and F-CAT treatments. The ALLEGRETTO WAVE EYE-Q light sources, especially the illumination for the operation microscope, are designed to enable optimal treatment by the user. In order to avoid unnecessary discomfort for the patient, the lighting should be switched on for as short a time as possible. The laser treatment should take place in a quiet and relaxed atmosphere in order not to distract the attention of the patient. The patient should lie in the middle of the bed, the head should rest comfortably on the headrest. Make sure that nobody bumps against the bed during the procedure of the laser treatment.
