Orbital hemorrhage and vision loss
Orbital hemorrhage followed 0.055% of 269,433 cosmetic eyelid operations, about 1 in 2,000, and permanent vision loss 0.0045%, about 1 in 22,000. A survey of 752,816 blepharoplasties found permanent vision loss in 0.0033%, about 1 in 30,000, with hypertension the most common risk factor. In a review of 93 retrobulbar hematomas from all causes, 22% ended in blindness, and surgical decompression and faster treatment predicted recovery.[1][2][3]
Dry eye
In 892 cases, 26.5% reported dry eye symptoms after surgery, more after combined upper and lower surgery and skin-muscle flaps. In 202 patients, dry eye lasted beyond 2 months in 2%, and 1 patient needed surgery. A meta-analysis of 12 trials found upper blepharoplasty reduced dry eye symptoms overall.[1][2][3]
Ectropion and lower lid malposition
Across 30 studies of lower blepharoplasty, lid malposition ranged from 0% to 12% and ectropion from 0% to 11.3%. In one comparison, ligament release raised ectropion to 19.2% from 3.8%. ASPS lists ectropion and lid lag, which is often temporary.[1][2]
Chemosis
Chemosis followed 26.3% of 892 blepharoplasties and 15.6% of lower blepharoplasties alone. Canthopexy, combined upper and lower surgery, male sex and lid laxity raised the risk.[1][2]
Lagophthalmos and difficulty closing the eyes
Removing orbicularis muscle with skin in upper blepharoplasty raised the odds of lagophthalmos 7.98 times. Lagophthalmos after surgery raised the risk of dry eye. ASPS lists difficulty closing the eyes as a risk.[1][2][3]
Brow descent
After upper blepharoplasty alone, the brow dropped in 24 of 70 patients, 34.2%, and in 58.3% of men.[1]
Wound separation, scarring and infection
Wound separation followed 1.4% of 2,376 upper lids and was more common in men and with fast-absorbing gut suture. After lower blepharoplasty, infection ranged from 0% to 1.6% and unfavorable scarring from 0% to 12%.[1][2][3]
Revision
Reoperation after lower blepharoplasty ranged from 0% to 9% across 21 studies, and most reported less than 3%. ASPS notes another operation may be needed.[1][2]
How long results last
ASPS describes the results as long-lasting, while the eyes continue to age. In 232 patients, fat repositioning eliminated the tear trough in more than 85%. In 1,152 patients 6 months after fat repositioning with a midface lift, 78% were extremely satisfied and 19.1% satisfied. Quality-of-life gains after ptosis repair held at 1.5 to 3.6 years.[1][2][3]
