Abstract
Purpose: The limbal zone of the scleral lens is intended to vault over an important area of the cornea that houses limbal stem cells necessary for corneal epithelial regeneration and limbal vasculature that supplies oxygen and nutrients to the avascular peripheral limbal cornea. An inappropriate fitting relationship in this peripheral curve system can negatively impact the limbal physiology. This paper aims to provide an overview of ocular sequalae associated with inappropriate limbal clearance and to discuss strategies for scleral lens practitioners to identify, manage, and overcome the fitting challenges in the limbal peripheral system of a scleral lens.
