Researchers tested how diathermy (electromagnetic heating) and cryosurgery (freezing) affected the strength of rabbit eye tissue. They found diathermy significantly weakened the sclera (the eye's outer wall), while freezing treatment caused little to no damage. This suggests electromagnetic heating can compromise tissue integrity in ways that mechanical alternatives do not.
