FIELD: medicine, ophthalmology.
SUBSTANCE: the present innovation deals with detecting clinico-functional parameters by studying patient's lacrima due to crystallographic technique. For this purpose one should measure relative width of peripheral zone of crystallization and detect the availability of transitional area between crystallization zones; and if relative width of peripheral crystallization zone is above one seventh of crystallogram's radius and it is possible to observe transitional area between peripheral and central crystallization zones one should diagnose keratoconus at its early stage.
EFFECT: higher accuracy of diagnostics.
