Ophthalmic eye surgery knife illustration
The instruments used in eye surgery are nearly microscopic, and the use of them in real applications is fairly gruesome, an illustration was the most ideal solution. I found some resource images but none were quite right so I had to render by hand the eye prior to converting it to a vector illustration.
Placing the knife was the final task, and showing dimension on the blade and handle. An Adobe Illustrator drawing is much better to look at than an actual photo of eye surgery.
