Which instrument is primarily used during chalazion surgery?

During chalazion surgery, the primary instrument utilized is a clamp. This tool is crucial for stabilizing the eyelid and ensuring that the surgical site remains secure and accessible during the procedure. The clamp helps by positioning the tissue correctly, allowing the surgeon to perform the necessary incisions and evacuate the chalazion effectively.

While other instruments like a dilator, forceps, and scalpel may be used in conjunction with the clamp, they serve different purposes. For instance, a scalpel is used to make the incision, forceps could assist in handling tissue, and a dilator might be employed to open up cavities or ducts. However, the clamp's role in stabilizing the eyelid directly supports the success of the surgery, making it the primary instrument for this specific procedure.
