Cataract surgery is among the most cost-effective of health interventions. Numerous studies have proven that the quality of life and economic benefits of restoring sight far outweighs the treatment costs

The Fred Hollows Foundation has supported several key studies to measure these benefits and demonstrate the value of long term funding for eye health care.

VISIONARY Study in Vietnam

The VISIONARY study showed that restoring sight allows people to return to work and helps to lift their families out of hardship and poverty. The study measured people’s wellbeing while they were affected by cataract blindness and then again, 12 months after undergoing cataract surgery. The post-surgery follow-up showed positive improvements to people’s employment, finances, physical wellbeing and mental health.

Cataract Impact Study

The Cataract Impact Study is evidence that the benefits of restoring sight last for the long term. The study found that 6 years after having their sight restored by cataract surgery, people had sustained improvements to their financial situation and quality of life.  The gap had been closed in their economic and social wellbeing.
