Critical factors to predict efficacy of orthokeratology in inhibiting axial elongation in myopic children.

ABSTRACT:

Background

The efficacy of orthokeratology (Ortho-K) in controlling myopia is influenced by many complex factors, which makes predicting the effect of myopia control a complicated task. This study aimed to analyze the relevant factors that can predict the axial length elongation (ALE) in patients wearing Ortho-K, including baseline ocular parameters, genetic factors and lifestyle habits.

Methods

In this retrospective study, 542 eyes from 300 myopic children wearing Ortho-K were reviewed from the Optometry Centre of Peking University People's Hospital from January 2022 to December 2023. Baseline characteristics such as age, gender, spherical equivalent refraction (SER), horizontal visible iris diameter (HVID), mean keratometry value (mean K), corneal astigmatism, corneal ecce
