PHOTOCHEMICAL LIGHT SOURCE RADIANCES OF THIS INSTRUMENT
LA (without crystalline lens) : 352 mW/ (cm2·sr)
LB (with crystalline lens)
: 338 mW/ (cm2·sr)
MEANING OF LB AND LA
Spectrally-weighted photochemical radiance LB and LA give a measure of the potential hazard that
exists for a beam of light to cause photochemical damage to the retina. LB gives the measure for
eyes in which the crystalline lens is in place. LA gives this measure for aphakes in which the lens
has not been replaced by a UV blocking intraocular lens or for the eyes of very young children.
The value stated for an SL-1E gives a measure of hazard potential when the instrument is operated at maximum intensity and maximum aperture. Values of LB or LA over 80 mW/(cm2·sr) are
considered high for beams which wholly fill a dilated pupil.
The retinal exposure dose for a photochemical hazard is a product of the radiance and the exposure time. For instance, at a radiance level of 80 mW/ (cm2·sr), 3 min irradiation of the dilated (8
mm diameter) pupil would cause the retinal exposure dose level to attain the recommended exposure limit. If the value of radiance were reduced to 40 mW/ (cm2·sr), twice that time (i.e. 6 min)
would be needed to reach the recommended limit. The recommended exposure is based on calculations arising from the American Conference of Governmental Industrial Hygienists (ACGIH)
Threshold Limit Values for Chemical Substances and Physical Agents (1995-1996 edition).
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.
While no acute optical radiation hazards have been identified for SL- 1E 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 a greater risk. The
risk may also be increased if the person being examined has had an exposure with the same
instrument or any other ophthalmic instrument using a visible light source during the previous 24
h. this will apply particularly if the eye has been exposed to retinal photography.

OPTIONAL ACCESSORIES
HRUBY LENS
Used for observation of the fundus and posterior segment of the vitreous body.
In routine applications, only the anterior segment of the vitreous body can be examined
because of the refraction effects of the cornea and crystalline lens. However, with the Hruby
Lens, examination of the fundus and the posterior segment of the vitreous body is possible.
Operation procedure
(1) The pupil should be well dilated by administering a mydriatic approximately 20 minutes
before the examination.
(2) Remove the hole cap to insert Hruby lens guide plate in the hole of carrier arm so that the
groove of guide plate fits with guide pin on the microscope arm.
(3) Insert the lower end of the Hruby Lens shaft in the groove on the guide plate.
(4) Center the illumination and microscope arms so that they face the patient's eye.
(5) Align lever, shown in the illustration below, with the center of the microscope's field of view.
Then move the lever backward and forward to position close to the patient's eye.
(6) Use the joystick to focus on the fundus.
The slit width and length will have to be adjusted to reduce the undesirable reflections
seen in the field of view.
(7) To view a different segment, either turn the microscope and illumination arms or have the
patient alter fixation by manipulating the fixation target.
