Eye surgery patient. Patient sitting in a chair after an eye operation at Kwale eye hospital in Kenya. The ball over her eye is tied in place to reduce the amount of swelling following the operation. Common and debilitating eye conditions in Kenya include cataracts and trachoma infections, both of which can be treated relatively easily and cheaply, but can lead to blindness if not treated.
