Article Synopsis
  • The study investigates how non-toric ortho-k lens decentration affects higher-order aberrations (HOAs) and astigmatism, utilizing AI to predict the impact.
  • Using a Medmont E300 Video topographer, the research analyzed 249 corneas, examining changes in topography data before and after the lenses were worn.
  • The results indicate significant changes in various aberration terms post-ortho-k, with AI successfully predicting the direction and magnitude of decentration in lenses with accuracies of around 70%.

Purpose: To improve the effectivity of patient-specific finite element analysis (FEA) to predict refractive power change (RPC) in rigid Ortho-K contact lens fitting. Novel eyelid boundary detection is introduced to the FEA model to better model the effects of the lid on lens performance, and stress and strain outcomes are investigated to identify the most effective FEA components to use in modelling.

Methods: The current study utilises fully anonymised records of 249 eyes, 132 right eyes, and 117 left eyes from subjects aged 14.

Article Synopsis
  • The study aimed to explore how different design parameters of Ortho-K contact lenses influence changes in the eye's refractive power using a mathematical model.
  • Researchers analyzed data from 249 eyes, focusing on three wear duration groups, to assess changes in corneal shape and refractive power before and after using the lenses.
  • Results showed significant correlations between lens design features (like base and reverse curves) and refractive power changes, particularly in the initial wear group, suggesting that lens design more strongly affects short-term wear outcomes.
