Outcomes of Levator Resection at Tertiary Eye Care Center in Iran: A 10-Year Experience

PURPOSE To assess outcomes of levator resection for the surgical correction of congenital and acquired upper lid ptosis in patients with fair to good levator function and evaluation of the relationship between demographic data and success of this operation. METHODS In a retrospective study, medical records of patients with blepharoptosis who had undergone levator resection over a 10-year period and were followed for at least 3 months were reviewed. RESULTS Overall, 136 patients including 60 (44.1%) male and 76 (55.9%) female subjects with a mean age of 20 ± 13.8 years (range, 2 to 80 years) were evaluated, of whom 120 cases (88.2%) had congenital ptosis and the rest had acquired ptosis. The overall success rate after the first operation was 78.7%. The most common complication after the first operation was undercorrection in 26 cases (19.1%), which was more prevalent among young patients (p = 0.06). Lid fissure and margin reflex distance (MRD(1)) also increased after levator resection (p < 0.001). Age, sex, type of ptosis, amblyopia, levator function, MRD(1), lid fissure and spherical equivalent were not predictive of surgical outcomes of levator resection. CONCLUSIONS Levator resection has a high rate of success and few complications in the surgical treatment of congenital and acquired upper lid ptosis with fair to good levator function. Reoperation can be effective in most cases in which levator resection has been performed.
