comparison of mersilene mesh and autogenous fascia lata in ptosis correction

purpose: to compare mersilene mesh and autogenous fascia lata in the management of low-function ptosis. methods: a randomized clinical trial was performed on 31 eyelids with poor levator function. patients were randomly assigned to two groups: 16 eyelids in the mersilene mesh group and 15 eyelids in the autogenous fascia lata group. results: nine patients with congenital unilateral and 11 patients with bilateral ptosis underwent sling procedure. there was no difference between the two groups in terms of functional (lid fissure height stability) and cosmetic (lid margin contour) results. dermatochalasis was seen more in the fascia lata group (10 cases) compared to the mersilene mesh group (2 cases). extrusion of mersilene mesh occurred in 2 eyelids. conclusion: mersilene mesh has favorable long-term functional results and a low rate of complication. this material may be an alternative to autogenous fascia lata as a suspensory material in ptosis surgery.
