Brief summary
Orthokeratology lens is an effective method for myopia control. This study analyzed the effects of treatment zone decentration on axial length elongation in adolescents with orthokeratology lens.
Detailed description
Orthokeratology lens is an effective method for myopia control. This study aimed to investigate the effects of treatment zone decentration on axial length elongation in adolescents with orthokeratology lens in 1 year. Other factors that may affect axial growth were also analyzed.
