The position of the eyelid relative to the pupil is a key factor in determining whether you need blepharoptosis repair or blepharoplasty. Blepharoptosis pertains to the eyelid margin being lower than it should be and can be addressed by blepharoptosis repair. Dermatochalasis denotes excess skin over the eyelids, which causes that hooded, tired-looking appearance which can be corrected by undergoing a blepharoplasty procedure. Unfortunately, it is common for ptosis to be overlooked because a plastic surgeon assumes that performing blepharoplasty will automatically improve the look of drooping eyelids. This leads to the eyelids still looking droopy, in spite of just having the surgery. On the other hand, it is not unusual for some people to have both dermatochalasis and blepharoptosis, which can sometimes pose a challenge when formulating a proper diagnosis and surgical plan. During a preliminary checkup, Dr. Amiya Prasad determines whether a patient has ptosis by lifting up the excess skin to see if it improves the eyelid margin or not. If the eyelid margin is still low, then it is safe to assume that the patient has eyelid ptosis, which can be easily fixed with the proper surgery.
