Claudia Hartley, the ophthalmic surgeon, and her team in Borneo have been in touch to say they are cautiously optimistic that the procedure, to remove the cataract from Aan's eye, has worked. The optic nerve looked fine, which is a great sign. Aan took a long time to come round from the anaesthetic and her eyes were still closed as it started to get dark. Orangutan Foundation field staff will keep a close eye on Aan overnight and Claudia and her team will return in the morning to assess Aan’s vision.

We are still keeping our fingers crossed that her vision will be good enough for her to be released back into the wild.

Thank you to everyone who has donated to help Aan.  We will keep you updated when we hear more from the field.

Here's a short video of Aan, before the operation.
