This study aims : * To assess the efficacy of fluorometholone 0.1% one drop twice daily for four weeks in reducing the incidence of post-operative trachomatous trichiasis (TT) when given as adjunctive therapy with TT surgery in the programmatic setting * To assess whether such treatment is sufficiently safe for wide-scale implementation in TT programs. * To estimate the costs of adding fluorometholone 0.1% treatment to TT surgery per case of postoperative TT averted, and to characterize the value of such treatment under a range of plausible health economic circumstances
The investigators are pursuing an agenda to evaluate a new potentially cost-effective approach to improving trichiasis surgery outcomes: perioperative topical anti-inflammatory therapy. Inflammation-whether induced by the trachoma disease process or surgery itself-most likely contributes to progressive cicatrization leading to failure of lid rotation surgery in a clinically important proportion of TT cases. The investigators hypothesize that adjunctive topical fluorometholone therapy following trichiasis surgery will reduce the risk of recurrent trichiasis and will be acceptably safe. The rationale for the efficacy aspect of this hypothesis is that interruption of inflammation postoperatively would reduce postoperative scarring/contracture driven by ongoing disease-driven inflammation and/or surgically-induced inflammation thus reducing the incidence of TT recurrence (post-operative TT) and other inflammation-related outcomes.

Incidence of postoperative TT by one year, as determined by trained study team members
The primary outcome measure is the postoperative recurrence of trachomatous trichiasis (TT), defined as one or more eyelashes in the upper eyelid touching the globe or evidence of epilation (lash stubs) in the upper eyelid on examination, or a history of repeat trichiasis surgery at any time in the upper eyelid during the one year follow-up period after the baseline surgery.
