Late-onset Pseudomonas keratitis after radial keratotomy and subsequent laser in situ keratomileusis:: case report and literature review

Radial keratotomy (RK) was the most frequently performed procedure for the correction of myopia in the late 1980s and 1990s. Bacterial keratitis is a known complication of RK.(1-8) Although it is more frequent in the early postoperative period (days to weeks after surgery), bacterial keratitis can present even several years after the procedure and seriously complicate the visual outcome.(8) In this report we present a case of Pseudomonas keratitis presenting 15 years after RK and review reported cases of delayed-onset bacterial keratitis after RK, including spectrum of microorganisms, pathogenesis, possible risk factors, treatment and visual outcome.
