A closer look at the ball screw setup from the steering box. Please note that I’m completely wrong about the direction reversing by flipping the screw 180deg. The thread itself would have to change from a right hand thread to a left hand thread to reverse the direction. Sorry for the erroneous info! 
Thanks Eugene!

A piece of metal shot off from a grinder landed in this patient’s eye two days prior to his arrival in the emergency department. We use a very basic tool, a needle, to scrape the foreign body from the eye. This simple approach is often successful. However, incomplete removal of the associated rust ring sometimes occurs and in this case deeper buried fragments remained and were subsequently removed by the ophthalmologist using an ophthalmic burr.
