Eye Exam.

[vancouver604]

At my last check up at the ophthalmologist, the technician used a new instrument, the Diaton tomometer to measure my eye pressure. It read 21/23 which is way up than my previous readings around 16. When the doctor did it again in the office with the Goldmann tonometer, the reading was 15/16. There is such a big difference I don't know which is correct. Can someone enlighten me?

Thanks.

I believe that was the instrument used that gave the reading of 21/23. This was the first time being used on me.

Quite a difference in readings.
This claptrap device works through the eyelid.
No numbing drops required.
$2500 to boot.
