Water fractions in normal and senile cataractous eye lenses studied by NMR.
The state of water and water fractions in normal and senile cataractous eye lenses was studied by the NMR method. Combining NMR with vacuum dehydration provided additional information on multifractional samples. A new mathematical procedure is presented which separates the characteristic parameters of the different fractions and helps to determine the relaxation times and amounts of the fractions. The measurement accuracy enables separation of three different water fractions both in normal and in cataractous lenses.
