FLuorometholone as Adjunctive MEdical Therapy for TT Surgery (FLAME) Trial

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
