Recently, I heard of a patient who improved her dry eye-related pain by using clarified butter, or ghee, in her eye. She had a chronic course of pain related to the dry eye and had tried multiple therapies. Nothing seemed to work as well as the ghee.
I have to say that I am very happy that this patient found something to help her problem. However, in general, I recommend that patients be wary of using products not designed for ocular use in the eye.
