title: Evaluation of lower blepharoplasty treated with the SmartLipo 1064-nm system and its clinical implications: A retrospective review.
abstract: BACKGROUND
  This study used the SmartLipo 1064-nm system to remove herniated orbital fat tissue to improve lower eyelid appearance. A retrospective review of 128 patients was performed to evaluate the size of prominent fat pads and complications.
  
  
  METHODS
  Altogether, 128 patients underwent a procedure using the SmartLipo 1064-nm system via postseptal access, which helped locate fat tissue more precisely. Digital photographs were taken preoperatively and at one week and six months postoperatively. Eyebag sizes were determined preoperatively and six months postoperatively using the Non-Contact 3D Digitizer.
  
  
  RESULTS
  Altogether, 118 primary and 10 revision patients (average age 31 years) were placed in one of two groups: mildly protruding fat pads (group 1, 86 patients) and moderately protruding fat pads (group 2, 42 patients). After injection of about 1 ml of anesthetic and 1 ml of 0.9% iced saline on each side, the patients received an average 450 joules of energy delivered at 20 Hz and 3 W. Postoperatively, the eyebag's height, depth, and area were significantly reduced in both groups (р = 0.000). The main symptoms (swelling, chemosis, engorgement, and pain) subsided within 5-7 days.
  
  
  CONCLUSIONS
  The SmartLipo 1064-nm system with postseptal access, a minimally invasive procedure, can be used to correct mildly and moderately prominent fat pads.
