title: Clinical trial comparing autogenous fascia lata sling and Gore-Tex suspension in bilateral congenital ptosis.
abstract: OBJECTIVE
  To study the effect of autogenous fascia lata sling (AFLS) versus Gore-Tex suspension (GTS) regarding the functional and aesthetic outcomes in patients with bilateral congenital ptosis.
  
  
  METHODS
  A prospective comparative randomized single-center study enrolled 110 patients with bilateral congenital ptosis. One group (n=55) underwent AFLS and the second group (n=55) underwent GTS. Exclusion criteria were good levator function, absent Bell's phenomenon, and abnormal ocular motility. Follow-up period was 2 years. Functional outcome was measured from digital photos by analysis of upper eyelid margin position relative to the superior limbus and classified as very good (<3 mm), good (3-5 mm), poor (>5 mm), and recurrent. Aesthetic outcome was assessed in terms of lid contour, symmetry of eyelid height, and lid crease presence. Complications were also reported.
  
  
  RESULTS
  Failure rate (recurrence and complications) was less in AFLS (P=0.035). Symmetrical lid height and good contour were more frequently attained by AFLS (P=0.007 and 0.047, respectively). However, the frequency of very good, good, poor, recurrence, lagopthalmos, ectropion, infection, and formed lid crease individually showed no statistically significant difference (P=0.252, 0.482, 1, 0.489, 0.438, 1, 0.618, and 0.506, respectively).
  
  
  CONCLUSIONS
  AFLS is a better choice in surgery for patients with bilateral congenital ptosis because it has fewer complications and a lesser recurrence rate than GTS.
