Treatment of recalcitrant Acanthamoeba Keratitis with Photoactivated Chromophore for Infectious Keratitis Corneal Collagen Cross-Linking (PACK-CXL)

Abstract: Purpose To describe a case of recalcitrant Acanthamoeba Keratitis (AK) complicated by medical non-compliance and medication intolerance that was successfully treated with photoactivated chromophore for infectious keratitis corneal collagen cross-linking (PACK-CXL). Observations A 31-year-old male presented with right eye pain and redness in the setting of fresh water exposure and scleral contact lens wear. He had lack of a response to treatment with antiviral therapy fo… Show more

“…Photo-activated chromophore for keratitis corneal cross-linking (PACK-CXL) has shown benefits as an adjuvant therapy for the treatment of AK [117][118][119]. PACK-CXL with both riboflavin and rose bengal has been found to exert significant anti-amoebic activity [117].…”

“…31 Patients underwent ablation to an average depth of 254 µm until infectious tissue was no longer seen. 31 A few case series in refractory cases have reported success with riboflavin cross-linking with ultraviolet A light 32 or rose bengal photodynamic antimicrobial therapy (RB-PDAT) with green light. 33 Both processes are theorized to generate free radicals that have significant antimicrobial properties without significant corneal toxicity.…”
