Light toxicity

WARNING! As extended, intensive illumination can damage the retina, the use of the device in the examination of the eye should not be prolonged unnecessarily. The illumination of this slit lamp emits a radiation in the range between 400 and 750nm. The retinal dose for a photochemical risk is composed of the product of the radiance and the exposure time. If the radiance is halved, the time until the exposure time limit value is reached will double accordingly. To date, no acute, optical radiation hazard has been detected in slit lamps. Nevertheless, we recommend keeping the intensity of the light reaching the patient's retina to the minimum possible for the respective diagnosis. Children, people with aphakia and people suffering from eye conditions are most at risk. An increased risk may also occur if the retina is exposed to the same or a similar device with a visible light source within 24 hours. This applies, in particular, if the retina has been photographed with a flashbulb in advance. The light from this instrument may be dangerous. The risk of eye damage increases with the exposure time. An exposure time with this instrument at maximum intensity of longer than 152 seconds exceeds the guideline value for a risk.

Operation

Setting the eyepieces

NOTE! The eyepieces must be individually set prior to the first examination in accordance with the refraction of the examiner. Insert the provided focus test rod (32) in place of the protective cover (14) and turn its black projection surface at a right angle to the microscope axis. Return the illumination and microscope to the central position (0°).

ring with dioptre scale (33) such that the projected slit can be seen in focus. The setting is performed from the (+) to the (−) side at low magnification. The pupil distance should then be set on the microscope.

5.2 Preparing the patient • In order to attain a solid basis for the forehead and chin to rest on, the table height should be selected such that the patient sits bent over forward.

• To ensure that only the part of the eye being examined is illuminated, the slit height should be set accordingly.

• Parts which come into contact with the patient should be cleaned with a dry cloth prior to every use.

• The lamp must be switched off after every examination. 5.3

Operating the instrument

WARNING! The device must be switched off after every use. Otherwise there is a risk of overheating when a protective dust cover is employed.

• Use the turn screw (7) to set the chin rest (6) in such a way that the patient’s

eyes are at the same height as the black mark (4) on the sides of the head rest. 7

• Switch on the illumination by turning the switch on the power supply. • Adjust the height of the slit lamp by turning the control lever (30) until the lumi• The rigid control lever (30) gently inclined towards the examiner can be used to

push the entire instrument until the slit appears approximately focused on the cornea. This initial setting is verified with the naked eye. Fine tuning is performed by tilting the control lever, which is easily controlled at the top end, while observing via the stereo microscope (22). • The slit width is set left or right with the rotating knob (17), as is the angle between the stereo microscope and illumination. • The slit image can be set vertically, horizontally or as diagonally as required by turning the illumination facility on the control knob (20) (locking points at 45°, 90° and 135°; stops at 0° and 180°; scale in 5° increments). • To ensure that unimpeded binocular fundus examination in the optical section is also possible at lateral angles of between 3° and 10°, a short mirror (12) is used, the illumination turned 90° using the locking screw (20) and tilted in 5° steps using the latch (27), and the illumination and microscope turned to the central position (0°). • The magnification of the stereo microscope can be changed on the slit lamp BM 900 by changing the lenses using the lever (24) or exchanging the eyepieces. • Front-lens glasses and contact glasses are used to examine the ocular fundus. Diffuse illumination: • A diffuse illumination is achieved by positioning the diffusor (8) upstream. This enables overview monitoring and can be used for taking overview images with the Imaging Module. Indirect illumination: • For observation in regredient light (indirect illumination), the centering screw (26) is loosened in order to move the slit image out of the center of the visual field. Tightening the screw centers the slit image again. Slit tilting: • The latch (27) can be used to tilt the illumination in 5° steps. This creates an angled light beam during horizontal slit orientation. Tilting the slit enables reflex-free examination with contact glasses (fundus and gonioscopy) and magnifying glasses.

and the 'S' symbol appears in the viewing window. In some examinations of the fundus, this star is projected onto the ocular fundus and is also visible to the patient, who is asked to focus on the center hole of the star. This shows the examiner the point where the patient's vision is most focused. A typical use of the fixation star is close to the macula during laser treatment. The projection of the fixation star can also be used to identify microstrabismus. The fixation star is usually used with upstream red removal filter.

Microscope and eyepiece

The magnification of the microscope can 42 43 44 45 46 47 48 be altered by changing the lens mounted in a revolving turret piece or by exchanging the eyepieces. Only the lever (48) is to be adjusted, from 1× to 1.6×, when changing the lens. In this instance, the examination need not be interrupted; nor is a new adjustment of the microscope needed. This change will alter the overall magnification from 10× to 16× (on the 10× eyepiece) and from 25× to 40× (on the 25× eyepiece) respectively. 42. Magnification changing lever 46.

Decommissioning

The LED illumination can be switched off with the illumination control. The device power supply remains switched on and the switch illuminates green. To switch the system off completely, the rocker switch must be set to the 0 = 'OFF' position. This results in double pole disconnection from the mains. NOTE! Disconnect the power supply from the mains if you do not intend to use it for an extended period of time. © HAAG-STREIT AG, 3098 Koeniz, Switzerland - HS-Doc. No. 1500.7200492-04170 – 17.

Where P is the maximum output power rating of thet ransmitter in watts (W) according to the transmitter manufacturer and D is the recommended separation distance in metres (m). Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey a, should be less than the compliance level in each frequency range b Interference may occur in the vicinity of equipment marked with the following symbol: NOTE 1: At 80 MHz and 800 MHz the higher frequency applies. NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people. a. Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which this product is used exceeds the applicable RF compliance level above, this product should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating this product. b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m. c. Possible shorter distances outside the ISM bands do not contribute to improved application in this table.
