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.
5

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