Aman is doing well. Every day he is coaxed to the bars using food and drink and then receives his daily eye drops to help with recovery. He has shown definite signs of seeing which is great news.



Here Caroline used a pipette to drop the solution into Aman's eyes. Soon, he will be released into his outside enclosure.

The operation was sponsored by the Orangutan Appeal UK, with volunteer donations going towards Aman's aftercare.

Aman is recovering very well after being the first adult orangutan ever to have cataract surgery performed on him. The vets checke up on him this morning and everything is fine. Aman will now have to stay indoors for a week ot two whilst he recovers. It is improtant to keep him confined so that it is easy to check up on him, to apply his daily eye drops and to avoid exposure to direct sunlight.

The vets had to use an enormous amount of drugs to keep him unconscious during the operation so he slept for a few hours afterward the operation and woke up feeling very groggy. He has been sitting around feeling sorry for himself, closing his eyes some of the time but thankfully he has not been rubbing his eyes so all should go well. The vets will return again on Sunday for a final check up before returning to South Africa.

He has been looking around at things which is a new behaviour and we are sure that his sight has returned which is fantastic news. Aman celebrated the successful operation with a fresh and tasty dragonfruit.

The Great Orangutan Project made it possible for the world's first cataract operation on an adult orangutan yesterday. With funding for the operation coming from the Orangutan Appeal UK, and lengthy preparation from Keith Lloyd and Caroline Bellhouse and other GOP team members, Aman was operated on by two world-class experts.

It was a tense time but incredibly awe inspiring. At first Aman was moving about as Dr Stegmann was trying to insert a line into Aman's arm to give him steady dosage of drugs, That freaked people out somewhat as a large male orangutan started to wake up surrounded by the operating team and the press core, but they soon got him to sleep and then Dr Izak started the operation itself.



Ultrasound was used to disperse the cataract. The lens is like a jelly covering and crystals can start forming onto it. As they coalesce, they form into one continuous layer we know as a cataract. All it takes is sound waves to move the crystals off the lens and into the fluid of the eye. The fluid is then sucked out and new clear fluid injected. This is what happened for Aman and he is now recovering well.

We will know whether he will see very shortly and keep you updated.
