Summary
The objective of this study is to determine if corneal topography can be used to predict the
fluorescein pattern of keratoconus lenses on the eye. A corneal topography image will be
taken and the computer selected lens will be placed on the eye. After placement of the lens
color photographs will be taken of the eye's fluorescein pattern and compared to the
computer predicted pattern.
Clinical Details
Official title: Objective and Subjective Correlation Between Clinical Fluoroscein Patterns and Theoretical Patterns Using the Medmont Corneal Topographer
Study design: Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Supportive Care
Primary outcome: There will be no inter-patient comparison. Bearing and elevation fluorescein patterns will be compared between the actual (photo) and theoretical (computer generated) fluorescein patterns.
Secondary outcome: Improved comfort
Detailed description:
Subject population: keratoconus patients who have not undergone corneal surgery 100 subjects
who come to UIHC for their contact lens care. We will approach them at their visit. We will
not call potential participants from a database.
If topography is impossible to capture. Concommitant Corneal Disease Minors will be excluded
Eligibility
Minimum age: 18 Years.
Maximum age: N/A.
Gender(s): Both.
Criteria:
Inclusion Criteria:
18yrs of age or older diagnosis of keratoconus contact lens wearer
Exclusion Criteria:
Concommittant corneal disease or surgery Inability to capture topography measurement
