Cryosurgery is a technique in which abnormal tissue is destroyed through
freezing. Special instrumentation chilled by liquid nitrogen is employed.
Veterinarians use cryosurgery primarily to treat several types of eyelid
problems in dogs.

Misdirected eyelashes growing towards the eye can cause pain or even
corneal ulceration. Freezing the hair at its root usually ensures that it will not
grow back.

Nodules on the eyelid of older dogs are most commonly tumors of the
meibomian gland. These tumors are very sensitive to freezing. Cryosurgery, in
most cases, allows these masses to be completely destroyed with minimal
loss of surrounding healthy tissue.
