6.2 PREPARING THE PATIENT AND USING THE SLIT LAMP Parts of the slit lamp coming in to contact with the patient should be cleaned in accordance with these instructions prior to the examination. Tomey recommends the use of disposable hygienic chinrest tissues on the chinrest before the patients place their chin on it.

6. INSTRUCTIONS FOR USE 6.1 SETTING THE BINOCULARS

Never use the instrument if visibly damaged and periodically inspect it for signs of damage or misuse.

It is vital that the binoculars are optimised for the user’s optical correction in order to obtain focused binocular images.

1. Remove the Test Bar locating hole cover plate (19) and place the test bar focus in the test bar location hole at the base of the microscope arm. To access the location hole first remove the cover. The test bar should be set with the flat projection face towards the Slit Lamp Microscope. The illumination and the microscope should be in the zero degrees position. 2. Turn on the Slit Lamp and set the slit to full width (18), set the magnification to x16 (31). 3. Adjust the eyepieces pupillary distance by holding both eyepiece bodies and rotating them inwards or outwards until they are correct for your PD.

19 31

1. The patient should be as comfortable as possible and with the patient in the chinrest adjust the chinrest height (7) so that the patient’s eyes are level with the height marking (4) on the chinrest support. 2. Focus the eyepieces using the test bar as described earlier, and if you have not already done so set them to your interpupillary distance by holding both eyepiece bodies and rotating them inwards or outwards until they are correct for your PD. 3. Switch on the illumination, making sure the rheostat (25) is set to a low level to minimise the patient’s exposure to light hazard. 4. Rotate the joystick (24) until the light beam is at eye level. 5. Holding the joystick vertical, move the slit Lamp base towards the patient until the slit beam appears focused on the patient’s cornea. 6. Adjust slit width (18), magnification (31), slit rotation (13) & slit angle etc. as required to perform the examination. 7. Loosening slit offset centering knob (16) to allow the slit image to be moved off centre for scleral illumination. Tightening the knob will re-centre the slit image in the centre of the visual field of the microscope.

4. Turn both eyepieces (32) to maximum plus (+) correction. 5. Close one eye, and with the other eye look through the microscope slowly turning the open eye eyepiece towards the minus (-) position until the image of the test bar is in focus. Stop. 32 6. Repeat the above process for the other eyepiece. 7. Make a note of the positions of the eyepieces so that you can set them quickly if the Slit Lamp has been used by another clinician. 8. Note – younger examiners are recommended to compensate for their ability to accommodate by further adjusting the eyepieces by minus one (-1) or minus two (-2) dioptres.

7. ROUTINE MAINTENANCE The maintenance outlined below should only be carried out once the main power cable has been disconnected. If you have any problems that are not covered by the procedures described below, contact Tomey GmbH or your local supplier.

7.1 LED SYSTEMS LED’s typically have a life exceeding 10,000 hours of continuous use and therefore can be considered as a non-consumable item that will not require changing by a user. Whilst this is a significant life expectancy, we suggest that the Slit Lamp is always switched off between examinations to conserve energy and LED life. In the unlikely event of an LED failure please contact Tomey or your local distributor for guidance on the replacement procedure. 7.2 REGULARLY INSPECT THE DEVICE FOR DAMAGE OR DIRT Routinely clean as per section 3 on page 6 cleaning instructions.

7.3 CLEANING AND CHANGING THE MIRROR The mirror is front surfaced to avoid ghosting of the projected light and therefore is very delicate and will need to be replaced when the surface deteriorates. The mirror should be cleaned only with a soft clean lens cloth. The mirror is an interference fit in its holder and can be removed by grasping it firmly and pulling it out of its holder. Slide in the replacement mirror taking care to avoid touching the reflective surface. Care must be taken to keep the objective and the eyepiece lenses clean – use only soft clean lens cloths to clean optical surfaces. 7.4 ELECTRICAL CONNECTIONS Routinely check all electrical connections, cables and connectors. To access the bulb connections see earlier in this section for guidance.
