Abstract

We sought to identify the relative importance placed on quality of life indicators amongst other patient-specific determinants of cataract surgery in a 12-month prospective study carried out at Princess Alexandra Eye hospital in Edinburgh attending 6 consultant teams. Data collection was carried out covering three major domains:visual function: (1) visual acuity, contrast sensitivity, retinal straylight measurement, (2) cataract morphology: Oxford cataract classification scale (3)quality of life:VF14, Massof and Sparrow Questionnaire. Patient factors predicting surgical selection reflective of current practice were best-corrected visual acuity, brunescence grades and straylight measures, rather than quality of life scores across all grades of presenting severity for all consultant teams. Reducing thresholds for surgery and a “ceiling effect” may explain the poor predictive power of vision-specific quality of life scales in current cataract surgical selection.
