Optimizing early diagnosis and treatment of acanthamoeba keratitis through corneal scraping

Elevated SPK is the most frequent early feature of AK and may mimic contact lens-related sterile keratitis. Corneal scraping is a valuable diagnostic tool that enables earlier detection and improved outcomes. PHMB monotherapy is effective in early AK, while delayed diagnosis and prior steroid use may lead to disease progression and necessitate surgical intervention.
