Core Insights - The research published in the international ophthalmology journal "BMJ OPEN OPHTHALMOLOGY" evaluates and compares the effectiveness and quality of life related to vision for children and adolescents wearing orthokeratology lenses (OK lenses), defocus glasses (DS glasses), and single vision glasses (SVS glasses) in China [1][2][3] Group 1: Research Findings - The study involved a cohort of 93 myopic children aged 7 to 17, divided into three groups wearing OK lenses, DS glasses, and SVS glasses, with a follow-up period of one year [1] - The results indicated significant differences in axial length growth among the three groups: the OK lens group showed an increase of only 0.18±0.08 mm, while the DS lens group had 0.27±0.08 mm, and the SVS lens group had 0.36±0.09 mm [2] - The OK lenses were found to control axial growth approximately 33% better than DS glasses and 50% better than SVS glasses, highlighting the advantages of newer lens types in preventing myopia progression [2] Group 2: Quality of Life Assessment - The study assessed quality of life using the internationally recognized "Children's Refractive Error Quality of Life Questionnaire" (PREP), which covers various dimensions such as distance vision, activity ability, and peer evaluation [1] - OK lenses demonstrated superior performance in multiple quality of life indicators, attributed to factors such as not needing to wear glasses during the day, unrestricted movement, reduced appearance anxiety, and clearer vision [2] - However, OK lenses had lower comfort scores compared to single vision glasses and required more complex maintenance, while DS glasses had lower scores in "near vision" due to their optical design [2] Group 3: Practical Implications - The research provides comprehensive insights for parents and doctors, indicating that while OK lenses have overall better performance, they may not be suitable for all children due to the need for strict screening of eye health and potential infection risks from improper maintenance [3] - DS glasses and SVS glasses are suggested to be more appropriate for children in conditions with limited hygiene or those unable to comply with nighttime lens wear [3]
