A rescued koala named Ruben, is put under anaesthesia while being treated for cataracts at Eye Clinic For Animals (ECA), a specialist veterinary ophthalmology practice, while being rehabilitated before a planned release back into his natural habitat, in Sydney, Australia, July 28, 2020. Ruben was captured from a low tree by a main highway, in an area where koala habitat is being encroached upon by urban sprawl. Koalas near main highways, are at high risk of being hit by a car when moving amongst trees. REUTERS/Loren Elliott SEARCH "KOALAS ELLIOTT" FOR THIS STORY. SEARCH "WIDER IMAGE" FOR ALL STORIES
