The article focuses on the Contact Outcomes Questionnaire (COQ) which helps to assess the functional vision. COQ is a responsive, valid, reliable and easy-to-implement instrument which can be used for assessing visual function after cataract. The COQ was developed by using Rasch analysis to reengineer the 18-item visual disability assessment.
