Conjunctival Rebound After Scleral Lens Wear

Completed · Not applicable

Conditions studied: Conjunctival Diseases

In brief

Scleral lenses, customized rigid contact lenses that land on the soft and spongy conjunctival tissue overlying the sclera, will be fitted on 15 subjects with normal ocular surfaces. The purpose of the study is to determine the amount of conjunctival compression caused by the devices and the length of time required for the shape to recover from compression.
