1. CORNEAL DIAMETER- HVID OPTOM FASLU MUHAMMED. 2. ï¨ Technique 1: ï¨ Corneal Topographer :use the biometric ruler within the corneal topography software program to measure your patientâs horizontal visible iris diameter (HVID). ï¨ It may be necessary to measure at a 45 degree oblique angle as the topographer may cut off part of the cornea in the horizontal plane.
Then, the elevation of the line of sight can be read off on the scale. The Vernier can be read to 10', but it requires a magnifier to do this. The clinometer can read easily and accurately angles of elevation that would be very difficult to measure in any other simple and inexpensive way.A fairly common use of a clinometer is to measure the height of trees, which is easily done.ith the levelling rod, the HI can easily be obtained. Set the index at 0Â°, and the clinometer becomes a level. Sight the rod from close by, and read the HI. This can, of course, be done by simply making a mark on a wall just in front of your eyes, and then measuring its height.
