California gorilla treated for cataract

A team of eye experts has operated on an unusual patient, a gorilla. The San Diego Zoo Safari Park in California says a cataract was removed last month from the left eye of a 3-year-old western lowland gorilla. The gorilla, named Leslie, was given a muscle blocker to keep her still while a team that included anesthesiologists and an ophthalmology team from UC San Diego Health removed the cloudy lens and replaced it with an artificial lens. Dr. Chris Heichel has performed thousands of such operations but says it's his first on a gorilla.
