Candida parapsilosis Infection After Crescentic Lamellar Wedge Resection in Pellucid Marginal Degeneration

Abstract

Infectious keratitis after corneal lamellar surgery is a rare complication. In this report, we present unexpected complications aftercrescentic lamellar wedge resection (CLWR) and their treatment in a patient with pellucid marginal degeneration. A 42-year-old malepatient developed fungal keratitis due to Candida parapsilosis in the late postoperative period after CLWR. Infection was controlled withmedical treatment. However, recurrent intraocular infections and cataract formation occurred, probably due to capsular damage andinoculation of microorganisms into the crystalline lens during antifungal drug injection. Lensectomy was performed due to cataractprogression and recurrence of the infection when treatment was discontinued. Amphotericin B was administered to the anterior chamberat the end of the operation. Four months later, an intraocular lens was implanted and corneal cross-linking treatment was performed. Atthe last visit, visual acuity reached 9/10. This case shows that good visual acuity can be achieved with appropriate treatment of fungalkeratitis and all associated complications after CLWR.
