FIELD: physics, optics.
SUBSTANCE: disclosed is a method of testing a laser device, designed for carrying out eye operations. The laser device is fitted with a contact element which is transparent for laser radiation and has a mating surface for bringing into close contact with the eye to be treated. When carrying out the testing method, a test object is placed on the mating surface, said test object being transparent for laser radiation at least in a region corresponding to the treatment region of said object. Laser radiation is then transmitted into the test object resting on the mating surface while simultaneously changing the focus position according to a given test pattern in order to form visible structures in the test object.
EFFECT: simple testing method which enables to estimate accuracy of positioning the focus of a laser device for carrying out eye operations.
