An observational cross-sectional study on the corneal endothelium of medium-term rigid gas permeable contact lens wearers

Highlights •Short-term miniscleral contact lens wear significantly alters limbal radius and scleral elevation. •No corneal flattening was found as a consequence of short-term miniscleral contact lens wear. •Scleral flattening was not fully reversed 3 h after lens removal in majority of...

Introduction: The advent of high oxygen permeability (Dk) of rigid contact lens materials has reduced complications related to hypoxia when using scleral contact lenses (ScCLs). However, new issues and complications have emerged. Some of these issues and complications are caused by the nonoptimal fitting...

Highlights •The posterior corneal curvature after scleral lens wearing has never been studied. •A flattening curvature appears in nasal quadrant in intracorneal ring patients and in inferior hemisphere in keratoconus. •The cornea is slightly thinner after scleral lens wear except...
