Official title

Comparison of Keratometric Tear Break Up Time (KTBUT) to Fluorescein Tear Break Up Time (FTBUT)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of the research is to determine if putting fluorescein onto the eye (most common test done for dry eye syndrome) is an accurate way to measure dry eye symptoms. The investigators can avoid placing any foreign substance into the eye by using a manual keratometer. Therefore, the investigators want to compare the measurements of tear breakup time using fluorescein with using a novel method, a manual keratometer and then compare these measurements to a validated dry eye symptoms questionnaire. All qualifying patients who were scheduled in the Jones Eye Institute Clinics for a complete eye exam were offered information about the study and invited to participate. Participants were recruited from February 29, 2009 to April 14, 2009.Participants who did not meet the study protocol's inclusion and exclusion criteria were not included the study or study data analysis. All subjects eyes were measured for KTBUT and FTBUT.
