Fungal infections such as keratomycosis are one of the most difficult conditions to treat. Approximately half of patients with keratomycosis do not respond to antifungal treatments and carries a higher risk of developing endophthalmitis. If this problem is not treated promptly and effectively, it can lead to vision loss. The use of Posaconazole, a newer triazole, for keratomycosis has attracted new interest due to its broad spectrum and good ocular penetration. Therefore, we conducted a systematic review to assess and conclude the efficacy of posaconazole for refractory keratomycosis. We conducted a systematic review according to PRISMA guidelines. A comprehensive search in PubMed, Scopus, ScienceDirect and Google scholar was conducted from inception to January 2025. Duplicate publications, review articles and incomplete articles were excluded and the quality of the articles were assessed using a standardized tool. The database searches identified a total of 2668 articles. A thorough review of the abstracts and titles led to the exclusion of 1209 items. Finally, we identified 6 articles through full-text reading and analysis, which included 11 patients. All cases reported were successfully treated with posaconazole. In conclusion, posaconazole possibly effective, especially for refractory cases.
