Because people who have dry eyes before surgery have a greater chance of experiencing this problem postoperatively, we recommend an examination by an ophthalmologist before blepharoplasty is performed. Rarely, there may be other problems after surgery such as persistent drooping or retraction of the eyelids or darkening of the lids because of permanent retention of blood pigments in the skin. These undesirable side effects frequently can be treated satisfactorily. Complete loss of vision in an eye is an extremely rare complication of blepharoplasty. Temporary visual blurriness occasionally may occur after surgery because of alterations of the tears, but the problem typically is short-lived.
Most patients indicate that their eyes look and feel more rested and youthful after blepharoplasty.
In general, it is a relatively safe and straightforward operation. Mayo Foundation for Medical Education and Research.
