Cataract surgery has come to the Houston Zoo! Jonah, a California Sea Lion who weighs in at 400+ pounds wasn't seeing well. So, Anesthesiologist Dr. James Bailey and ophthalmologist Dr. Carmen Colitz came to town to remove cataracts from Jonah’s eyes. Working with the Houston Zoo Sea Lion team and veterinarians, they removed marble-sized clouded lenses from each of Jonah’s eyes to improve his vision. Jonah is 22 years old.
