Summary:FIELD: medicine, particularly, ophthalmology. SUBSTANCE: device has case and radiation source. Helium-neon laser is used as a radiation source. Device is provided additionally with laser position lock. Laser radiation may be directed to cornea at a right angle relative to cornea center normal. Laser carries a diaphragm. Screen with scale is mounted for obtaining relative deflection of spot of reflected beams of monochromatic radiation from external and internal surfaces of cornea, respectively, and positioned at a distance of 20-40 cm from patient's eye. EFFECT: enhanced accuracy of determination. 3 dwg
