METHOD FOR TREATMENT OF PROGRESSIVE MYOPIA AND LENS FOR TREATMENT OF PROGRESSIVE MYOPIA Russian patent published in 2018 - IPC G02C7/04 A61F9/13 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine, namely to ophthalmology, and can be used to treat progressive myopia. Determine the patient's various parameters of his eyes. Also various parameters of the lens are determined by the parameters of the patient's eye. According to the parameters of this lens, a lens is manufactured which comprises at least two smoothly transferring central and annular regions on the outer surface. Central region of the lens has a circular shape with a diameter of about 2,000 mcm to about 4,000 mcm and a Y value of the optical power additive at the measurement points. Annular region of the lens, concentric to the central region, has values for the additive to the optical force at the measurement points. Values of Y and y additives are determined by different formulas. Next the lens is put on the patient's eye, combining its central area with the pupil of the patient. Measure the visual acuity of the patient in the lens. After this patient wears a lens during treatment period, lasting from about two months to about six months, during at least his wakefulness. Determine after the end of treatment period, the patient again has the parameters of his eye and the need to continue treatment.

EFFECT: method is effective of treating progressive myopia and the manufacture of an individual lens, which allow creation of a controlled peripheral myopic defocus on the retina of the patient's eye during the entire period of his wakefulness, regardless of the resistance of his cornea, and also to minimize the effect of catarrhal and/or inflammatory diseases on the effectiveness of treatment by obtaining an array of optical power values for each point of the lens optical zone and the parameters of the patient's eye.
