Weekly Changes in Axial Length and Choroidal Thickness in Children During and Following Orthokeratology Treatment With Different Compression Factors.

ABSTRACT:

Purpose

To determine the influence of compression factor upon changes in axial length and choroidal thickness during and following orthokeratology treatment.

Methods

Orthokeratology lenses of different compression factors (one eye with 0.75 D and the fellow eye with 1.75 D) were randomly assigned to 28 subjects (median [range] age: 9.3 [7.8-11.0] years). Ocular biometrics were measured weekly for 1 month of lens wear and after lens cessation until the refraction stabilized (mean duration: 2.8 ± 0.4 weeks). Changes between eyes, and the associations between axial shortening and choroidal thickening with other ocular biometrics were analyzed.

Results

There were no significant between-eye differences in the changes of ocular biometrics (all P > 0.05). After adjust
