Introduction: Clinical studies have shown that vision related quality of life in cataract patients with multifocal intraocular lenses (IOL) is significantly better than vision related quality of life of monofocal IOL patients. The aim of this study is to compare the multifocal and monofocal intraocular lens with regard to long-term general quality of life (QOL) of patients undergoing cataract surgery. Method: This study is a randomized, prospective, multicenter clinical trial. Patients receiving bilateral monofocal IOL and patients receiving bilateral multifocal IOL are interviewed before and after cataract surgery using a structured questionnaire. QOL is measured by the Visual Analogue Scale (interval and categorical), the Time Trade-Off (TTO) and the Standard Gamble (SG). The following hypotheses are formulated: 1) QOL is increased after cataract surgery, 2) QOL of patients receiving a monofocal IOL is different from the QOL of patients receiving a multifocal IOL. Statistical analysis were performed using t-tests for independent samples to compare pretest and posttest results. Furthermore a paired t-test was used to compare then-test scores with posttest scores. Results: Demographic description of the study population: 12 men and 35 women were interviewed. Mean age was 72 years (s.d.=8.47). Level of education was stratified in low (n=30), middle (n=10) and high (n=7) education. Pretest QOL-weight's are: VAS (interval): 7.8 (s.d.=1.9), VAS (categorical): 7.1 (s.d.=1.1), TTO: 6.4 years (s.d.=2.8), SG: .88 (s.d.=.09). Posttest QOL-weight's are: VAS (interval): 7.8 (s.d.=2.3), VAS (categorical): 7.4 (s.d.=1.8), TTO: 7.3 years (s.d.=2.6), SG: .81 (s.d.=.90). Differences between the pretest and posttest were not significant. Conclusions: General QOL of cataract patients is not increased after cataract surgery. However, the possibility of increased vision related quality of life remains unclear.
