The lone practitioner of his self-made technique in the 40’s and 50’s, he used this method to effectively removed eyelid cancers in a way that allowed 100% cure, while limiting the tissue damage and maintaining the maximum amount of eyelid tissue. In fact, a 96 year old patient of mine told me of her interaction with Dr. Mohs for just such a surgery done on herself, when she lived in Chicago. She searched and searched for someone who would not leave her eyelid deformed…and Dr. Mohs was her savior.

Dr. Mohs died at 92, in 2002, a pioneer who ‘practiced in the wilderness’ until the world beat a path to his door.
