    The study analyzed the effectiveness of corneal refractive therapy lenses with different optical zone designs in managing myopia in children.

  • 2

    Two hundred children aged 7-12 years with myopia participated, divided into four groups based on initial myopic refractive power.

  • 3

    Participants wore CRT lenses for at least 8 hours nightly, with follow-up assessments to measure myopia control effects over one year.

  • 4

    Smaller optical zones (5 mm, 5.5 mm) were found to be more effective in suppressing axial length elongation in myopic children.

    The study emphasizes the importance of individualized fitting of OK lenses based on patient-specific factors for optimal outcomes.
