Orthokeratology Lens Wear for 2 Years in Children Did Not Alter Tear Film Lipid Thickness by Non-Invasive Interferometry

PurposePrevious studies suggest that overnight orthokeratology (OOK) may be detrimental to tear function.We aimed to investigate the effect of OOK on lipid layer thickness (LLT), blink pattern, and meibomian gland and elucidate the relationship of these variables.MethodsThirty-seven participants who wore OOK lenses every night for at least 2 years
