How do they freeze the eye ball for surgery?

Freezing the eyeball for surgery typically involves the use of a local anesthetic rather than actual freezing. An ophthalmic surgeon may apply a topical anesthetic to numb the surface of the eye, or inject a local anesthetic around the eye area to reduce sensation. In some cases, cooling techniques may be used to minimize damage to surrounding tissues, but the eye itself is not frozen in the traditional sense. The goal is to ensure patient comfort and safety during the procedure.
