What about applanation tonometry, as used in clinical opthalmology?
Basically it involves pressing a flat plate against the cornea with a
standard pressure. If IOP is low the flattened area of the cornea will
be large and vice versa. Details in the textbooks (eg Basic Clinical
Opth. by Calbert Philips, Churchill Livingston).
