Study Summary
Purpose: To develop a screening metric by examining both the characteristics of the preoperative tear film and the intracellular signaling pathways of conjunctival goblet cells in order to determine if there are certain characteristics which might predict those patients who will experience serious dry eye symptoms and complications after refractive surgery. Research Design: This study is a twelve-month prospective non-randomized investigation. Methodology: In conjunction with psychometric questionnaires and various measures of tear film quality (e.g. Schirmer's test, tear break up time, etc), impression cytology will be used to assess the intracellular signaling pathways of conjunctival goblet cells and to determine if alterations in this pathway exist. Alterations in this pathway would result in a reduced response by the mucin secreting conjunctival goblet cells thereby promoting the development of dry eye after refractive surgery.
Interventions
