Impact of cataracts and cataract surgery on quality of vision.

The QoV was completed before and three months after cataract surgery in 212 patients across four groups: first or second eye surgery, with or without ocular comorbidity. The study found that cataracts in one or both eyes causes a similar loss in subjec-tive quality of vision, which is also irrespective of the presence of ocular comorbidity. Cataract surgery resulted in a large and comparable improvement in subjective quality of vision, regard-less of ocular comorbidity and first or second eye surgery.
