SALIENT FEATURES

1. Measuring under slit lamp microscope provides important information such as inspection of the eye and measurement of intraocular pressure (IOP).

2. Numerical value is precise. the Tonometer’s own error is only +0.066Kpa.
3. Get numerical value of IOP directly. No need to look up tables or do

matrixing.And Pt=’P’, i.e. tgPt-tgP0=0.56k, normal k=0.0215, then:

Pt: P0=1.0281. So Pt adds 2.8% comparing with P0.

4. The Hardness of sclera does not affect the numerical value, since the Change in

The Volume of eyeball is only 0.56 mm³ .

5. Combine with the measurement method of Schiotz Tonometer, counting the

hardness of sclera can be done.

6. The measuring-pressure can be calibrated, which guarantee the stability over a

Long Period of time and reliability of measurement.
