Аdaptation and quality of vision in glasses with lenses for the control of stellest myopia with built-in high-spherical microlenses

AIM: Evaluate the visual adaptation and vision quality of glasses with Stellest lenses.

MATERIAL AND METHODS: A total of 35 children aged 8–13 years (average: 10.5±0.27 years) with mild and moderate myopia (average: 3.15±0.19 dpt) in glasses with Stellest lenses and 30 children aged 8–13 years (average: 10.4±0.3 years) with mild and moderate myopia (average: 2.66±0.2 dpt) in monofocal glasses as the control group. Refraction and visual acuity (OS) were assessed after the appointment of glasses. Ergonomic tests were conducted 3–4 months after the children started wearing them. At 3–4 weeks after they started wearing glasses, all patients filled out a questionnaire of 8 questions.

RESULTS: The monocular distance in the Stellest glasses averaged 1.17±0.02, and the specific values were 1.24±0.03 for binoculars, 1.09±0.02 for monofocal glasses, and 1.160.02 for binocular glasses. Near monocular OZ in Stellest glasses averaged 0.95±0.01 and 0.96±0.01 for binocular glasses; the values were 0.96±0.01 and 0.97±0.01 for monofocal glasses. The minimum mesopic contrast sensitivity in Stellest glasses was 3.76±0.04 (with a reference value of 4) and 3.44±0.1 in the trial frame (p <0.05). In the conditions of the glare effect, the values of 7.47±0.08 for the Stellest glasses (with a reference value of 8) and 6.76±0.2 for monofocal glasses were observed (p <0.01). In monofocal glasses, the corresponding indicators were 3.71±0.09 and 7.2±0.14. Under the conditions of the gler effect, the indicator was 0.84 higher than that of the trial frame (p <0.01). The tendency to lower ergonomic indicators in Stellest glasses has been revealed. The subjective assessment of the quality of vision was high in both groups

CONCLUSION: A preliminary assessment revealed highly functional and ergonomic performance and good portability of glasses with Stellest lenses.
