Determining Rate of Change in Corneal Clearance of Scleral Lenses in Habitual Lens Wearer

Overview

About this study

The purpose of this study is to determine rate of change in corneal clearance of scleral lenses in habitual lens wearers. Also, to determine the increase corneal thickness in established scleral lens wearers following 2 hours of lens wear, Determine any differences in IOP as measured with the diaton in a habitual lens wearer before scleral lens wear, with the sclera lens on the eye and after lens removal. (Compare to temporal pneumatonometer and Goldmann IOP after lens removal.), and evaluate tear exchange during scleral lens wear by observation and by assessing changes in optical density of the fluid reservoir as measured before and after instillation of NaFl in the inferior fornix.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:

  • Scleral lens wear in at least one eye for at least one year with wear at least 5 days a week. 
  • No significant corneal scarring that would interfere with Pentacam measurements.
  • Patient will be asked not to wear the lens on the day of the study until after the initial Pentacam measurement is taken.

Exclusion Criteria: ,

  • Dense corneal scarring (that would interfere with Scheimpflug images). Inability to tolerate measurements.

Note: Other protocol defined Inclusion/Exclusion Criteria may apply.

Eligibility last updated 3/20/23. Questions regarding updates should be directed to the study team contact.
