INDICATIONS FOR USE

This device is intended to be used only by suitably trained and authorized healthcare professionals.
CAUTION: Federal Law restricts this device to sale by or on the order of a physician or practitioner.

Intended use/purpose of the instrument
This Tomey Slit Lamp is an AC-powered slit lamp biomicroscope and is intended for use in eye examination of the anterior eye segment, from the cornea epithelium to the posterior capsule. It is used to aid in the diagnosis of diseases or trauma which affects the structural properties of the anterior eye segment.

Brief description of the instrument
This Tomey Slit Lamp can either be mounted onto a custom tabletop supplied by Tomey or can be mounted on a third parties tabletop (refraction unit) by suitably trained technicians. The Tomey Slit Lamp consists of 5 assemblies; Illumination Tower; Observation System; XYZ Translation Base; Chinrest Assembly and a Table Top with power supply and accessory drawer. The light intensity is controlled by a variable rheostat located on the XYZ Translation Base. There are a number of selectable filters allowing the ser to control the characteristics of the examination light. Many ophthalmic instruments illuminate the eye with intense light. The light intensity on the Tomey Slit Lamp is continuously adjustable from maximum to zero.

SAFETY

2.1 PHOTOTOXICITY

CAUTION: The light emitted from this instrument is potentially hazardous. The longer the duration of exposure, the greater the risk of ocular damage. Exposure to light from this instrument when operated at maximum intensity will exceed the safety guideline after 81 seconds While no acute optical radiation hazards have been identified for slit lamps, 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. The 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 fl ash bulb in advance. Tomey GmbH shall on request, provide the user with a graph showing the relative spectral output of the instrument.

INSTRUCTIONS FOR USE

6.1 SETTING THE BINOCULARS

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

  1. Remove the Test Bar locating hole cover plate (16) 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 (14), set the magnification to x16 (27).

  3. Adjust the eyepiece pupillary distance by holding both eyepiece bodies and rotating them inwards or outwards until they are correct for your PD.
    TOMEY TSL 4000Z Z Series Slit Lamp - fig11

  4. Turn both eyepieces (28) 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.

  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.

6.2 PREPARING THE PATIENT AND USING THE SLIT LAMP

Parts of the slit lamp coming into 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. Never use the instrument if visibly damaged and periodically inspect it for signs of damage or misuse.

  1. The patient should be as comfortable as possible and with the patient in the chinrest adjust the chinrest height (6) so that the patient’s eyes are level with the height marking
    (3) 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 (21) is set to a low level to minimize the patient’s exposure to light hazard.

  4. Rotate the joystick (20) 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.
    TOMEY TSL 4000Z Z Series Slit Lamp - fig13

  6. Adjust slit width (14), magnification (27), slit rotation (13) and slit angle, etc. as required to perform the examination.

  7. To offset the slit for sclerotic scatter or retro illumination, rotate the illumination prism assembly (11) to the left or right as desired.

  8. When using the blue filter (12) the user may wish to insert the yellow barrier filter (9). The yellow barrier filter is out when the knob is up, in when it is down.

  9. When the examination is complete, set the rheostat to a low level and switch off the Slit Lamp.

Shut down after every use. In case the dust cover is used: risk of overheating.
