How do I earn the "I am a genius!" Achievement?

I recently bought Surgeon Simulator from the App Store and there are a list of achievements you can earn. I was scrolling through the achievements and I happen to see an achievement where you have to create a hammerhead shark. I am confused, so how do I earn this achievement?

The answer is quite simple actually. Take this achievement in literal terms and strike the patient in the head during an operation. I hope this helps!

You need to hit the patient in the head with a hammer to get this achievement . You will actually need to perform this procedure during the eye transplant.
