Quality of Life Before and After Cataract Surgery: Research in a Sample of Polish Patients

The goal of this paper is to present possible change in quality of life (QoL) in older sample of people with vision disturbances. The patients were investigated twice: before (N = 193) and 4 month after the cataract surgery (N = 69), by means of the scale for vision functioning, and the Life Quality Questionnaire (Schalock & Keith, 1993) extend with the items measuring health related quality of life (HRQoL). Two problems were formulated: To what extent are visual defects associated with the decreased subjective QoL? What changes are observed in perceived QoL during the period of treatment of visual defects? The patients reported significant increase of HRQoL, however they did not report similar increase of a general QoL. Few reasons are considered: overlapping of the content of visual function scales and HRQoL and different indices of a general QoL and HRQoL, lack of a proper postoperative care, low socio-economic status of the participants, and too high expectation concerning better functioning after the surgery.
