Measurement of visual functioning following first and second eye cataract surgery using Vision-Related Activity Limitation Item Bank.

Purpose: This study aims to compare visual functioning (VF) after first or second eye cataract surgery using the vision-related activity limitation (VRAL) item bank.

Methods: This prospective, interventional study included 787 patients (mean age, 58.2 years) with cataract undergoing cataract surgery (first eye surgery with/out ocular comorbidity, second eye surgery with/out ocular comorbidity) at a tertiary eye care center, South India, who were administered the item bank pre- and at 6 weeks postoperatively to assess change in VF.

Psychometric Properties of an Indian Translation of the Vision-related Activity Limitation Item Bank in Cataract.

Significance: The Indian translated and culturally adapted version of the vision-related activity limitation (VRAL) item bank is a validated instrument to assess the difficulty in performing daily activities by cataract patients and can also be used to capture self-reported changes in ability to perform daily activities after cataract surgery.

Purpose: The purpose of this study was to document (a) translation, cross-cultural adaptation of VRAL item bank into an Indian language, and (b) its validation using Rasch analysis in a South Indian cataract population.

Methods: At the first stage, a translated Indian version of VRAL item bank was produced using recommended procedures.
