Abstract Details

Purpose:

To determine the impact of cataract surgery on vision-related quality of life (VRQOL) and examine the association between objective visual measures and change in VRQOL after surgery among bilateral cataract patients.

Setting:

Eye Hospital in Ho Chi Minh City, Vietnam.

Methods:

A cohort of older patients with bilateral cataract was assessed one week before and one to three months after first or first and second eye cataract surgery. Visual measures including visual acuity, contrast sensitivity and stereopsis were obtained. Vision-related quality of life was assessed using the NEI VFQ-25. Descriptive analyses and a generalized linear estimating equation (GEE) analysis were undertaken to determine the impact of cataract surgery on VRQOL and the association between visual measures and change in VRQOL after cataract surgery.

Results:

Four hundred and thirteen patients were assessed before cataract surgery and two hundred and fourteen seven completed the follow-up assessment one to three months after first only and both first and second eye cataract surgery. Overall, VRQOL significantly improved after cataract surgery (p<0.001) and this improvement was significantly greater for patients who had both eyes operated on, compared to first eye surgery patients only (p=0.004). Binocular contrast sensitivity (p<0.001) and stereopsis (p<0.001) were also associated with change in VRQOL after cataract surgery. Visual acuity was not associated with VRQOL.

Conclusions:

Cataract surgery significantly improved VRQOL among bilateral cataract patients in Vietnam. Contrast sensitivity as well as stereopsis, rather than visual acuity significantly affected improvement in VRQOL after cataract surgery.
