Answer 1

Inside the surgery, an ear, nose and throat specialist was already at work on the patient, a diabetic.

He had inserted a tube in her nose and was removing tissues infected with mucormycosis, a rare but dangerous fungal infection. This aggressive infection affects the nose, eye and sometimes the brain.

After his colleague finished, Dr Nair would carry out a three hour procedure to remove the patient's eye.

"I will be removing her eye to save her life. That's how this disease works," Dr Nair told me.
