Scleral Lens Issues and Complications Related to a Non-optimal Fitting Relationship Between the Lens and Ocular Surface

摘要

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 relationship with the underlying ocular surface, which may pose a challenge in their management.
