DEVICE AND METHOD FOR DETERMINING INDIVIDUAL LENSES Russian patent published in 2019 - IPC A61B3/02 A61B3/28 A61B3/10 G02C7/04 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine, namely to ophthalmology. For the selection of individual contact lenses using the computer system receive data measuring the optical power of the eye of the patient, data of a given or actually measured optical power of the selected trial lens; data of the refraction of the patient's eye with the test lens fitted. Optical power transmitted by the test lens to the patient's eye is calculated on the basis of data obtained from an eye study and refraction studies. Efficiency factor is calculated using the calculated optical power transmitted by the fitting lens and the target or actually measured optical power of the test lens. Calculate the optical power of the test lens for the patient using the efficiency coefficient and the measured optical power of the patient's eye.

EFFECT: group of inventions improves the accuracy of selection of individual contact lenses for the patient by measuring the optical power of the eye without correction and using a trial lens.
