Cataracts is the leading cause of global blindness and visual impairment, despite it being treatable.

Most people experience at least one eye condition in their lifetime, and with the right eye care, most conditions are easily treatable. The same goes for cataracts – a condition that’s caused by the lens of the eye developing cloudy patches. 

The difference is: cataracts worsens over time. When it’s left untreated, sufferers develop severe vision impairment and even blindness.

That means in poverty-stricken communities, the most vulnerable in society (like children and the elderly) experience vision impairment and sight loss, simply because they can’t access or afford the necessary treatment.

Cataracts is preventable and treatable, which is why our team is working across 46 countries to provide free medical eye care to those who need it most.

Symptoms of cataracts include:

  • Clouded or blurred vision
  • Difficulty seeing in low light or at night
  • Headaches and sensitivity to bright light
  • Everything appearing ‘washed out’
  • Seeing a ‘halo’ around bright lights

Free treatment through mobile cataracts clinics:

Cataracts can be corrected through simple surgical interventions. Through our mobile cataract programme, we deploy our dedicated medical teams to hard to reach places around the world.

Our goal is to make sure vulnerable individuals aren’t suffering needlessly.

Our fight never stops. Every year we reach more communities than ever before

Watch cataracts surgery in action

Cataract surgery for adults is carried out under local anaesthetic. The procedure usually takes as little as 12-20 minutes to complete.

We recorded a time-lapse video of a cataracts operation that took place in our outreach camp in Damazine, Sudan.

Watch the video and see how a quick and uncomplicated surgery can change lives.

This 12 minute operation can transform the lives of people. It is nothing short of a miracle.
