The purpose of eyelid surgery is to rejuvenate the eyes so a person may appear more alert and refreshed. The doctor does not alter the shape and overall appearance of the eyes through blepharoplasty, so closing the eyes should not be difficult as the anatomy essentially remains the same and only extra biological materials are snipped away. One potential complication of upper eyelid surgery is the removal of too much skin, which can lead to difficulty closing the eyes. Dr. Schoenfeld is an experienced blepharoplasty surgeon, and he takes time to create proper measurements of the amount of excess upper eyelid skin prior to removal to avoid this potential complication.
