Purpose: To investigate the factors influencing final visual outcome of contact lens related infectious keratitis according to their clinical manifestations and culture results.
Methods: Twenty-five eyes of total twenty-five patients with contact lens related infectious keratitis between 2008 and 2014 were reviewed retrospectively. We evaluated clinical characteristics, ophthalmic and laboratory examination, and treatment. Also, we classified two groups as culture proven group and no growth group to identify factors affecting visual outcome.
Results: The best corrected visual acuity (log MAR) was improved from 0.76 ± 0.93 before treatment to 0.26 ± 0.38 after treatment. The organism was identified in 14 eyes (56%): Staphylococcus spp. accounted for 7 eyes (50%), gram negative rods for 2 eyes (14%), Pseudomonas spp. for 2 eyes (14%), Acanthamoeba for 2 eyes (14%), and miscellaneous for 1 eye (7%). There were no significant differences in prognosis between organism identified and unidentified groups and there were significant visual improvement regardless of culture result (p = 0.038).
Conclusions: If the infectious keratitis occurred in patients with wearing contact lens, broad spectrum antibiotic therapy should be helpful for better prognosis regardless of the detection of organism.
