Product Description
Slit Lamp

The Slit Lamp is Essentially and simple and generally under used piece of equipment. It consists of an illumination system and a binocular observation system, which when correctly aligned will result in a coincidental focus of the slit and microscope.

Illumination System

Basically and short focus projector projecting an image of the illuminated slit aperture on to the eyes. This part of the system should be flexible to allow various sizes and shape of slit beam. Usually a rheostat is incorporated and the lamp house can be rotated. Neutral density, Cobalt blue and red free filters are usually available and occasionally a diffuses and polarizes

Using the Slit Lamp

Commence the examination using the 10x eyepieces and the lower powered objective i.e. 1x. Use the lowest voltage setting on the transformer. Select the longest Slit length by means of the appropriate lever. Adjust the chin rest by means of control so that the patient eye's are approximately level with the black marker on the side of the head rest. Adjust the height of the slit lamp until the slit beam is centered vertically in the patient's eyes. Focus the slit beam in the eye by moving the joystick either toward or away from the patient. Coarse positioning can be effected by using the microscope but critical focusing should be carried out whilst viewing through the microscope. The slit width is variety by rotating either the left hand or right hand knurled control. To vary the angle between illumination and the microscope use one and other of these same controls as handle.

The slit should be set primarily in the vertical position, but any desired inclination can be achieved by means of the ball handle (notches at 45 degree, 90 degree, 135 degree, stop at 0 to 180 degree). By tripping the latch and tilting the slit lamp column. The beam can be introduced from as much as 20 degree below the horizontal. This is mainly use for carrying our goniscopy.

For observation by sclerotic scatter or other dissociated forms of examination the centering screw is loosened, so that slit image can be moved away from the center of the field of observation. The Image is centered again by tightening the screw. Carry out the techniques described below.
