Purpose: This study aims to evaluate when it is suitable to offer myopia control as management in progressed myopia. This case study-based development project describes the assessment and management of myopia management on daily work at an optometrist’s appointment. Methods: This clinical case study describes assessing and managing a patient with MiOYSMART lenses at a private optical-owned clinic from 2021-2022. A literature review was prepared as background information for the case study discussion. The literature search was made using Springer, Cochrane, and PubMed in January 2023. One hundred twenty-nine (n=129) texts were retrieved, and ninety-nine (n = 99) articles were deemed eligible for full-text review. Seven (n = 32) studies were included in the literature review. The IRB approval was not needed in this case study. The patient´s parents provided consent for participation. Results: MiYOSMART lenses can provide good myopia management. The case study patient was diagnosed with high myopia. In the case study, the patient´s visual acuity was 20/20 in both eyes with correction and without finger count (distance of 1 meter). This single case study can verify the myopia degrees in one year, as the literature said. The MiYOSMART patient brochure is a tool for patient guidance and follow-up visits. MiYOSMART lenses provide good results for managing myopia, as the literature said. The literature says, if optometrists have wider education and better knowledge of eye health, they can detect myopic defects better than those without wider education. Conclusion: Myopia progresses quickly and later causes many eye diseases. Optometrists have a wide knowledge of vision-related problems, and with good management possibilities, optometrists can offer wide and good management of myopia. Wider education of optometrists gives an opportunity for professionals and high-quality examinations for myopia patients.
