Brief 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.

Condition or disease Intervention/treatment Phase
Keratoconus Other: Comparison of fluorescein patterns Not Applicable

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

Arm Intervention/treatment
Active Comparator: 1 Other: Comparison of fluorescein patterns

Outcome Measures

Primary Outcome Measures :
  1. 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. [ Time Frame: 1 year after last subject is enrolled ]

Secondary Outcome Measures :
  1. Improved comfort [ Time Frame: one day ]
