Phase transitions in ocular tissue - NMR and temperature measurements.
The human cornea, sclera and lens is studied by nuclear magnetic resonance (NMR) measurements and temperature curves. The bound water fractions of these tissues have been determined as 3% in the cornea, 20% in the sclera and 17% in the lens. In contrast to other investigations we found freezing intervals near -1 degree C.
