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.
