The lacrimal gland is responsible for tear production and it is located beneath the tissues of the upper eyelid. There can be a very remote possibility of lacrimal gland injury with upper lid blepharoplasty, but not with lower lid blepharoplasty alone. However, tear film quality and quantity is often temporarily affected after blepharoplasty, and patients may notice dryness of the eyes after surgery. The dryness is almost always temporary, and is easily relieved with the use of over the counter artificial tears. For my patients with a preexisting problem with chronic dry eyes, I recommend that upper and lower lid blepharoplasty not be done at the same time. For most individuals, though, upper and/or lower lid blepharoplasty is a safe, effective way to enhance and refresh the appearance of the eyes.
