Which term denotes a round cutting blade used to mark or cut tissue such as the cornea or sclera?

Explanation:
A trephine is a round cutting blade used to mark or cut tissue such as the cornea or sclera. In eye procedures, trephination creates a precise circular opening, which is essential for tasks like preparing a graft bed or accessing inner tissues. The other terms don’t denote an instrument: stress lines and striae refer to surface markings or patterns in tissue, not tools, and the uvea is the vascular layer of the eye, not a cutting device.
