PURPOSE: To evaluate the effect of accelerated corneal cross-linking with photoactivated chromophore (PACK-CXL) as additional treatment for therapy-resistant infectious keratitis.
METHODS: In this interventional cohort study, 20 patients (11 men and 9 women), aged 65.5 (interquartile range = 21.5-78.5) years, who were hospitalized for moderate-sized therapy-resistant bacterial corneal ulcers (11/20 microbiologically confirmed) were treated with hypoosmolar 0.1% riboflavin solution and Ultraviolet A (UVA) irradiation for 3 minutes at 30 mW/cm (5.4 J/cm) as additional therapy to standard antimicrobial treatment.
RESULTS: We did not observe any adverse effects of accelerated PACK-CXL on the corneal stroma or limbus. The median ulcer size was 3.00 (2.63-4.50) mm, the median time to reepithelialization was 6.50 (5.00-18.0) days, and the mean hospitalization period was 8.5 ± 4.5 days. Tectonic keratoplasty became necessary in 1 patient (5%).
CONCLUSIONS: Our results suggest that accelerated PACK-CXL may provide an antimicrobial effect similar to the 1 low-intensity, slow setting (30 minutes at 3 mW/cm) and may be used as additional treatment in moderate-sized therapy-resistant infectious keratitis.
