Blepharoplasty
Preoperative Evaluation
Evaluation of any potential blepharoplasty patient includes the following:
-
a complete ocular examination that includes visual acuity testing and documentation
-
a history of prior periocular surgery
-
identification of amount and areas of excess skin, as well as the amount and contours of prolapsed orbital fat, in the upper and lower eyelids
-
presence or absence of lagophthalmos, which can lead to postoperative dryness and exposure keratopathy
-
evaluation of tear secretion or the tear film, which may be carried out through Schirmer testing, tear breakup time, or assessment of the adequacy of the tear meniscus
-
photographic documentation
Upper blepharoplasty
In addition to the assessments above, the examination before upper blepharoplasty includes the following elements:
-
visual field testing to determine the presence and degree of superior visual field defects (if needed for documentation)
-
evaluation of the forehead and eyebrows (including brow height and contour) to detect forehead and brow ptosis; the surgeon should make careful observations when the patient’s facial and brow musculature is relaxed
-
notation of the position of the upper eyelid crease
Lower blepharoplasty
Preoperative examination for lower blepharoplasty further includes
-
testing of the elasticity (snapback test) and distractibility of the lower eyelid; the surgeon should be alert to the possible need for horizontal tightening of the lower eyelids along with the blepharoplasty
-
notation and discussion of prominent orbital rims, if present; malar hypoplasia or relative exophthalmos may predispose the patient to postoperative scleral show after lower blepharoplasty
