Action 1. Position the patient’s head in front of the slit lamp using the
height adjustment of the head rest so that the eyes are level
with the red marking of the head rest.
The patient’s head must be pressed firmly against the head
rest.
2. Insert the clean and disinfected measuring prism into the
measuring prism holder as far as it will go. Hold the measuring
prism holder while doing so. Make sure that the extensible
measuring arm does not collide with the front or back limit
position of the motion range.
NOTE! The measuring prism has a graduated scale. The
measuring prism holder has a white and a red index line.
Please note the corresponding angle adjustment when
measuring spherical and toric curved corneal surfaces
(see
also Measuring spherical corneal surfaces [ } 24] and Measuring
toric cornea surfaces [ } 24]).
