A rescued koala named Ruben, who has cataracts, is tended to by veterinary ophthalmology nurse Mayara Galetti while under anaesthesia, as he is 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
