Step 11: Remove the cornea from the front eye hemisphere. Use a razor blade to puncture a small slit at the boundary between the cornea and sclera. Then insert the scissors into the slip and cut all the way around the cornea to remove it. Notice the thickness of the cornea. Compared to the sclera, the cornea is slightly less thick than the sclera.  (Cornea thickness = 0.5 mm vs. sclera = 1.0 mm).  Carefully observe the front side of the iris and pupil. Which structure of the eye would be just behind the pupil opening? Take the notes you need to record what you have observed so far.
