Abstract
Objective
To investigate vision-related quality of life (VRQoL) and associated factors in patients with cataracts and the outcomes of cataract surgery using the newly developed VRQoL instrument: the visual function questionnaire, 11-item Japanese version (the VFQ-J11).
Methods
A total of 457 patients scheduled for cataract surgery at 12 clinical sites from November 2008 through February 2010 were included in the study. The patients completed the VFQ-J11 before and 3 months after surgery. The VFQ-J11 was used to investigate factors associated with VRQoL of the cataract patients, the outcome of cataract surgery, and the predictors of improved VRQoL due to cataract surgery.
Results
In a multiple regression model, the VFQ-J11 score was significantly associated with corrected distance visual acuity in the better-seeing eye (better eye VA), and improvement in the VFQ-J11 score after cataract surgery was associated not only with improvement in the better eye VA, but also with improvement in the worse eye VA. Compared to one-eye cataract surgery, both-eyes surgery had a greater impact on VFQ-J11 score improvement.
Conclusions
The VFQ-J11 is a good measure of VRQoL in cataract patients. The present study indicates that by including the domains measured in the VFQ, the VFQ-J11 can provide valid data on VRQoL and be less of a burden for patients.
