你家孩子用对OK镜了吗？

Core Viewpoint - The article discusses the effectiveness and considerations of using OK lenses as a method for myopia control in children, emphasizing the importance of proper usage and selection criteria for suitable candidates [1][2][3]. Group 1: OK Lens Effectiveness - OK lenses, or orthokeratology lenses, can effectively control myopia with a control rate of 40% to 60%, particularly beneficial for children experiencing rapid myopia progression [3]. - Children aged 8 to 14 are identified as being in a critical period for myopia development, and OK lenses can help slow down axial elongation, reducing the risk of developing high myopia [3]. Group 2: Suitability and Selection Criteria - Not all children are suitable for OK lens wear; candidates should be over 8 years old, have a myopia progression of at least 75 degrees per year, and have myopia not exceeding 600 degrees with astigmatism not exceeding 150 degrees [4]. - Children with active eye conditions such as keratitis or conjunctivitis, poor hygiene habits, or those who are too young or non-compliant should be cautious about wearing OK lenses [4]. Group 3: Usage Guidelines and Maintenance - The fitting process for OK lenses is rigorous, requiring comprehensive assessments including corneal topography and tear function evaluation, with regular follow-ups every three months [6]. - Proper care includes daily cleaning with specialized solutions, hand washing before handling lenses, and avoiding prolonged wear, especially during illness [6]. Group 4: Comprehensive Myopia Prevention - OK lenses are not a standalone solution; a combination of methods including outdoor activities, limited screen time, and proper reading posture is recommended for effective myopia prevention [7]. - The article highlights the importance of early eye care and regular vision screenings for children aged 0 to 6, with a reported coverage rate of 95.4% for eye health services in this age group [11].
