A Study to Evaluate Fogging in Scleral Contact Lens


About this study

The purpose of this study is to quantify potential decreases in visual acuity experienced by patients who experience mid-day fogging during scleral lens wear, compare severity of subjectively reported fogging with clinical findings, and to explore the relationship between scleral lens fitting parameters and mid-day fogging.
