Purpose Microbial keratitis is an infective process of the cornea with a potentially and serious visual impairments. Contact lenses are a major cause of microbial keratitis in the developed countries especially among young people. Therefore, the purpose of the present study was to evaluate the frequency and microbiological characteristic of contact lens keratitis (CLK) in patients referred to the emergency department of Hospital Clinico Lozano Blesa, Zaragoza Methods This is a cross‐sectional study of all patients with contact lens induced corneal ulcers who were reffered to the Hospital Clinico Lozano Blesa in the last 6 months. An ophthalmologist examined patients with the slit‐lamp and clinical features of them were noted and infectious corneal ulcers were scraped for microbial culture. The contact lenses and their liquid storage were analyzed by microbiology. Results A total of 18 patients were recuited into the study. The cultures were positive in 36.36% of corneal samples and 80% of culture contact lenses. The most common isolated organism in contact lenses was gram negative bacilli showing cleaning and manteinance system falilure of this type of lenses. Two case of contamination of liquid lenses by fungi were recorded, candida parapsilosis y acremonium spp and two case of contamination by acanthamoeba. The most microorganisms found from the corneal scrapes were gram positive cocci and Pseudomona aeruginosa was the most common gram negative. Conclusions Due to the percentage of positive results in the cultures of contact lenses is higher than the percentage of corneal scrapings its realization is useful, beacuse the microorganism isolated in the ulcer is also present in maintenance fluids. Due to the high sensitivity of the main microorganisms to quinolones, are recommended as initial empiric therapy in infectious keratitis.
