ALCON HAND HELD AUTO-KERATOMETER

Measuring Technique

Once you have aligned the images 
correctly just release the 
measurement button and the 
reading will be taken.  The 
reading is complete when the 
green lights go off, a red light 
flashes once and you hear a long 
chirp.  You may now move the 
instrument away from the 
patient.

The reading will be shown on the 
display screen.  The reading is 
stored in the instrument while 
you take the reading on the second eye.
