I thought this would throw people. From front to back this is a green laser, a thimble scleral depressor (used to push on the eye to see the peripheral retina), a prism, a Kelman tipped phacoemulsification needle (used for removing cataract in cataract surgery), and a distometer (used to measure the distance from the front surface of the eye to the back surface of the lens in a pair of glasses). The eye docs love their toys and there are some very unusual ones out there!
Thanks for the comments!
My highest vote this challenge. I'm assuming this is some kind of caliper or other measuring instrument, distorted by placement near a prism? Whatever it is, the presentation is pristine, and I'm astounded this didn't score higher...
