Trephines, Surgical, Eye, Chalazion
Definition : Eye (ophthalmic) surgery trephines designed to cut and remove circular sections of eyelid inflammation masses (i.e., chalazions). These trephines are typically handheld, manual instruments consisting of sharp, beveled hollow cylinders of different diameters (usually from 1 to 2.5 mm) with circular-saw-like working edges and double windows for visualization of the trephine cuts. Eye surgery trephine components are usually attached to a manually operated common handle. Chalazion ophthalmic surgery trephines are used to excise chalazions in surgical procedures of the eyelids.
