1.4 Operation, environment NOTE! Only qualified and trained personnel should operate the equipment, the training is at the owner’s responsibility. Use only HAAG-STREIT accessories. WARNING! Shut down after every use. In case the dust cover is used: risk of overheating. FORBIDDEN! Never use the ocular to look at the sun. Never operate the instrument in the same room with combustible gases, volatile solvents (alcohol, benzol) or flammable anaesthetic agents.

1.5 Light toxicity WARNING! Because prolonged intense light exposure can damage the retina, the use of the device for ocular examination should not be unnecessarily prolonged, and the brightness setting should not exceed what is needed to provide clear visualization of the target structures. This device is fitted with protective filters, which limit the spectrum from 400 to 750 nm, see 4.2. The retinal exposure dose for a photochemical hazard is aproduct of the radiance and the exposure time. If the value of radiance were reduced in half, twice the time would be needed to reach the maximum exposure limit. While no acute optical radiation hazards have been identified for slit lamps, it is recommended that the intensity of light directed into the patient’s eye be limited to the minimum level which is necessary for diagnosis. Infants, aphakes and persons with diseased eyes will be at greater risk. The risk may also be increased if the person being examined has had any exposure with the same instrument or any other ophthalmic instrument using a visible light source during the previous 24 hours. This will apply particularly if the eye has been exposed to retinal photography. © HAAG-STREIT AG, 3098 Koeniz, Switzerland - HS-Doc. no. 1500.7001000-04140 – 2011 – 11

3.1 Adjusting the eyepieces NOTE! Before the first examination, the eyepieces should be adjusted singly to correspond with the refraction divergence of the examiner. Insert the provided focusing rod (a) in place of the protective cover (b) with the flat projection surface facing the microscope. Line up the illumination unit and the microscope in the central position (0°).

a)

• Adjust each eyepiece separately, by turning the knurled ring with the diopter • • • •

scale separately, until the projected slit is seen in focus. Adjust from (+) to (-) at low magnification. Younger examiners are recommended to make an additional correction on both eyepieces of −1 to −2 diopters each, to compensate for the accommodation that occurs as a result of convergence when conducting binocular examinations. The requisite pupil distance on the microscope can then be adjusted. The adjustable eyecup (c) serves to set up the correct working distance of the examiner to the eyepiece. For examiners without spectacles: pull out the eyecup fully to the extended position. For examiners wearing spectacles: push in the eyecup fully to the retracted position.

3.2 Prepare the patient • The height of the table must be selected to enable the patient to obtain a firm

b)

c)

rest for the forehead and chin.

• In order to ensure that only that part of the eye to be examined is illuminated and • •

to avoid disturbing glare, the height of the light beam should be appropriately adjusted. Those parts of the equipment coming into contact with patients should be cleaned with a dry cloth before each examination. Turn off the illumination of the lamp after each examination.

3.3 Operating the instrument • Move the chin rest (6) up or down with the adjustment screw (7) until the • • • • • •

• • •

• • •

eyes of the patient are level with the black mark on the headrest column (4). Focus the eyepieces (27) to suit your refraction by turning the knurled rings and then set to your interpupillary distance. Switch on the illumination unit by turning the power supply switch. Control level of slit illumination / knob on the power supply / 10% grey filter (see chap. 3.4). LI 900 see separate instructions for use. Rotate the joystick (36) until the light beam is at eye level. Microscope magnification is changed by rotating the magnification changer (13). Holding the joystick (36), inclined towards you, move the instrument base until the slit appears to be approximately in focus on the cornea. This coarse setting is achieved with the naked eye. Fine adjustments are obtained by rotating and tilting the lever while observing the image through the microscope (27). The slit width is adjusted to the left or right by means of the knob (19), which also adjusts the angle between the microscope and the illumination unit. The slit image is made vertical, horizontal, or given any desired angle by means of control knob (23) (notches at 45°, 90° and 135°; stops at 0° and 180°, scale in 5° steps). In order to ensure the possibility of conducting a binocular fundus examination in optical cross section without difficulty from side angles between 3 and 10°, the shorter mirror (11) should be installed, the illumination unit is rotated through 90° with the knurled control knob (23) and with the latch (32) in stages of 5°, the illumination unit and the microscope are turned to the centre position (0°). Loosening the centering screw (31) will allow the slit image to be moved off centre for scleral illumination. Tightening the screw will re-centre the slit image in the visual field of the microscope. Set the diffusor (12) in place for general observations. For examination of the posterior of the eye, preset lenses or diagnostic contact lenses have to be used.

A.4 Fixation lamp • The fixation lamp is lit as soon as the power supply switch is activated, then the fixation lamp (53) gets visible.

• The fixation target can be brought into any position by moving the bearer's • •

arm (49). This permits uninterrupted observation through the microscope and simultaneous guidance of the patient's eye to any desired position. This is especially advantageous in examining the fundus. It's a condition, that the patient's eye is correctly positioned at the headrest's height marker (52). Ametropia of the patient from +10 D to −15 D (50) can be corrected (51). Steady fixation of the eye is maintained as accommodation and convergence are avoided. 48 49 50

B.3.1 Compensating the weight of added components • Turn the joystick (60) down to its lowest stop, then loosen it by 1/4 turn. • Swing the microscope and illumination unit to one side. • Engage 1-3 springs depending on accessories. B.3.2 Engaging

Turn the screws (59) counter-clockwise until they are in the uppermost position.

B.3.3 Disengaging

Tighten the screws by turning them clockwise. • Lift the microscope arm with one hand. Release it and check whether it returns to the original position. This will not happen unless the maximum load has been added. • As a rule, it will be necessary to disengage as many relieving springs as required for ensuring that the arm and spring housing settle down in their original position. • The load is adequately counter-balanced when the weight of illumination unit and microscope with all permanently mounted components exceeds the compensating force of the springs by a small amount.
