Purpose. To develop a new approach to assessing the quality of vision in children with habitual correction, or in its absence, to determine reasonable indications for the appointment of a certain type of correction of ametropia. Material and methods. On the basis of the Doctor Sorokin office, 195 children (390 eyes) aged 5 to 18 years who applied for an appointment were examined. anamnesis about the beginning of the manifestation of ametropia, the time of the first treatment and the time of the first correction of ametropia were carried out. All applicants were divided into 4 groups: No correction, complete and incomplete correction, excessive correction and control group. All applicants underwent a complete ophthalmological examination: Determination of relative, absolute visual acuity and visual acuity with habitual correction (Shin Nippon CP), refractometry without mydriasis and with mydriasis, retinoscopy, keratometry (Huvitz HRK 7000), keratotopography. Biometrics, biomicroscopy with aspherical lens (spruce lamp Shin Nippon SL-40), direct and indirect ophthalmoscopy (Welch Allyn ophthalmoscope with retinoscopy nozzle). Optical coherence tomography – angiography (optical coherence tomography with Optovue Avanti angiography module). Full optical correction, portable eyeglass and contact vision correction (spherical, astigmatic, de-focal and ORT lenses). A study on the contrast of vision before correction and after complete correction of vision. A survey was conducted on the quality of vision before correction and after different correction options. We used traditional indicators of descriptive statistics – the number of observations (n), arithmetic mean (M), standard deviation (SD). To identify statistically significant differences between the groups, the nonparametric Mann – Whitney criterion was used, within each group parametric data were compared using the Student's t-test. The differences were considered significant at p < 0.05. Results. At this stage, 195 children aged 5 to 18 years of different genders were examined. All are divided into 4 groups [7]: Group 1 – no correction Group 2 – complete and incomplete correction Group 3 – excessive correction Group 4 – control group All children also underwent a study to determine the quality of vision with different levels of contrast. A trend is revealed showing an increase in the contrast of vision with a full-fledged correction. These are preliminary data that require further observation and statistical confirmation. Conclusion. The results revealed a trend confirming the already established fact that under-correction of myopia at the initial stage is not a successful therapeutic method of preventing myopia, and that full correction should be used to correct myopia. It is necessary to work out new tactical approaches in earlier diagnosis and timely full - fledged correction of any ametropia in the younger and middle age group. To strengthen explanatory work among parents and children, including through the mass media, about the need for early and full-fledged vision correction. About the need for regular preventive monitoring and treatment by ophthalmologists for the timely detection of ametropia.
