Comparing Myopia Treatments in Youth: Defocus Spectacles, Glasses, and Ortho-K
The research project titled "A Comparative Study on the Clinical Efficacy, Quality of Life, and Cost of Use of Peripheral Defocus Spectacles, Frame Glasses, and Orthokeratology Lenses in Myopic Children and Adolescents" aims to evaluate different non-surgical myopia correction methods in children. It focuses on assessing the impact of peripheral defocus spectacles, frame glasses, and orthokeratology lenses on the quality of life, clinical effectiveness, and costs associated with each method. The study is a prospective cohort study involving 300 children aged 13-17 years with myopia ranging from -1.00D to -6.00D. It aims to compare the psychological, social, and educational aspects of these correction methods, alongside their costs and clinical outcomes over a period of one year.
