A 22-year-old female developed sudden ocular symptoms two days after contact lens use. Examination revealed significant conjunctival injection, anterior chamber inflammation, and a corneal abscess with an epithelial defect. Despite initial moxifloxacin treatment, her condition worsened, requiring a switch to fortified vancomycin, ceftriaxone, and voriconazole. Cultures confirmed S. marcescens, allowing treatment to be streamlined to fortified ceftriaxone. The infection gradually resolved, with visual acuity returning to 20/20 and minimal residual scarring noted at one month.Keywords: Serratia marcescens, keratitis, contact lens, corneal abscess, microbial keratitis
