My husband has MOHs surgery next to his eye, and the eye is very red. Seems to be getting redder. Is this normal? (Photo)

It is very common to have some sensitivity and redness of the eye after any type of surgery on or near the eyelids. My concern from your photo would be an issue with the lower eyelid after the surgery, something called an ectropion. This outward turning of the lower eyelid can lead to increased exposure and mild damage to the surface of the eye. Over-the-counter lubricant drops and ointments are very effective to protect the surface of the eye in this case, but need to be used very frequently. If things continue to worsen I would bring up the issue with your surgeon.

Your photo suggests inflammation of the conjunctiva, or the clear covering of the eyeball.  With surgery near the eyelid and periorbital area, this swelling can be common, and can sometimes make the eye feel dry, scratchy, or like a foreign object is in the eye.  You don't say when your husband had his surgery, but redness and swelling can and often do increase in the first few days after surgery.  I suggest you contact your surgeon's office for recommendations; lubricating eye drops during the day and a gentle lubricating ointment at night can be a helpful step in this situations.  Best of luck.
