. Purpose: It is necessary to develop tools for patient selection to target cataract surgery to patients with the best expected outcomes. We used visual acuity, visual functioning 14 (VF‐14) test, the 15‐dimension health‐related quality‐of‐life questionnaire (15D) and the New Zealand priority criteria to evaluate the criteria for cataract surgery in a post hoc setting. Material and methods: Ninety‐three consecutive patients living in a defined rural area in Finland had cataract surgery as a part of the Pyhäjärvi Cataract Study in 2003. Success of cataract surgery was defined as improvement of visual acuity by at least 2 lines and/or improvement of visual function measured by questionnaires. Results: The patients with a visual acuity of 0.30 logMAR (0.5 Snellen decimal) or worse in the better eye and/or 0.52 logMAR (0.3 Snellen decimal) in the worse eye had successful surgery in 59–83% of cases depending on the definition of success. When subjective judgement was added, the success rates varied between 63% and 91%. Conclusion: Setting indication criteria, it seems sufficient to use two global questions in addition to visual acuity: one on the subjective view on disability, and one on a more neutral view on visual function, such as the 15D item on vision. The VF‐14 did not perform any better than the single item counterparts.
