Quadrant-Specific Changes in Corneal and Tear Fluid Reservoir Thickness for After 2 Hours of Wear

Objective:

To measure corneal swelling and thickness of the tear fluid reservoir (TFR) after wearing scleral lenses (SLs).

Methods:

Thirty-five participants had 1 eye fitted with each of three SLs (15.0-mm Jupiter, 18.2-mm Jupiter, and 18.0-mm Digiform). Scheimpflug images were obtained before wear, after application, after 2 hr of wear, and after removal. Initial and final TFR thickness and corneal thickness were measured in the central cornea and 3 mm from the center in the superior, inferior, temporal, and nasal quadrants.

Results:

Corneal thickness increased with wear, but no between-lens differences were observed in the superior (P=0.09), inferior (P=0.38), or temporal (P=0.53) quadrants. The greatest change in central and nasal cornea thickness was with the 15.0-mm SL (P
