A Prospective Observational Study of the Determinants of Current Cataract Surgical Selection

The principal aim of this research proposal was to develop quality of life and relevant visual function criteria to provide a rational decisional framework to be used as a basis for individual and policy decisions on cataract referral and surgery. There are two key objectives within this overall aim. The first is to identify reliable and effective quality of life and visual function criteria to determine the threshold for surgery for each individual patient in which false positive and false negative errors are minimized. The second is to provide a decisional framework in which risk factors may be incorporated to assess the likely outcome benefits from surgery.
