About

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.

Full 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

Enrollment: 18 patients

Sex: All

Ages: 18+ years old

Inclusion criteria

18 yrs of age or older with diagnosis of keratoconus and contact lens wearer

Exclusion criteria

Noncommittant corneal disease or surgery Inability to capture topography measurement

Trial design

18 participants in 1 patient group

Corneal Topographer Fluorescein Patterns

Description:

Use corneal topography to evaluate fluorescein pattern of rgp contact lens. Used corneal topography to develop theoretical fluorescein patters on a virtual eye. Theoretical lens developed by the topographer was ordered to compare to the actual fluorescein pattern on the actual eye.
