- Interventional
- Study Design
- Not specified
- Primary Outcome Measures
Name Time Method Anterior eye shape (corneal refractive power) changes will be measured using a Medmont E300 corneal topographer.[Measurements will be taken at baseline before any lens wear, then after 1 and 7 nights (primary timepoint) of orthokeratology lens wear of both the standard and modified lens designs. ]
- Secondary Outcome Measures
Name Time Method Peripheral refraction will be measured across the horizontal and vertical visual field meridians using the Shin-Nippon NVisionK 5001 autorefractor[Measurements will be taken at baseline before any lens wear, then after 1 and 7 nights of both standard and custom orthokeratology lens wear. ]
