Will a brow lift alone (without upper bleph) exacerbate dry eye? There is minimal excess skin if I push the brows up manually.

A properly performed conservative browlift (modified browlift) with very limited scalp incisions should help immensely and avoid worsening dry eye problems. Any procedure around the eyes can cause short-term worsening of the dry eye due to swelling but most people can tolerate it for 2-3 weeks.

This is a great question but one that cannot be answered based on your description alone. You are correct that anything that interferes with your eye closure can make your dry eye worse. Further, the fact that you require Restasis suggests that this is a fairly significant issue for you. In most cases, a conservative browlift should allow you to close normally and not worsen your dry eye. However, the key is to have a complete examination and find a conservative surgeon who won't be overly aggressive when treating your brow.

An eyebrow lift should not make dry eyes and worse as long as there is enough skin on the upper eyelids for good closure. If a previous blepharoplasty has been performed, you must proceed with caution. For many examples of  brow lifting procedures, please see the link and the videos  below
