To report a case of bilateral peripheral ulcerative keratitis after cataract extraction with a clear corneal incision in a patient with rheumatoid arthritis.

A 67-year-old woman was referred to our clinic with bilateral ocular pain and visual disturbances, 10 days after a cataract extraction in her right eye. The patient had undergone a cataract extraction with clear corneal incision in the left eye and the same procedure was performed in the right eye after 1 week. During the surgery, hyphema occurred because of the iris damage by the phacoemulsification tip. Slit lamp examination showed bilateral peripheral ulcerative keratitis around the incision site and diffused corneal edema. Topical instillation and systemic administration of antibiotic agents were given as treatment but the patient showed no improvement. Corneal culture and smear were performed and showed a negative result. Because the patient was previously diagnosed with rheumatoid arthritis and showed the characteristic finger deformity, she was diagnosed with a sterile peripheral ulcerative keratitis and was treated with oral steroid, sulfasalazine, and steroid eye drop. After 1 month of treatment, epithelial thinning of the cornea and peripheral corneal ulcer stopped progressing and showed corneal re-epithelization.

Because peripheral ulcerative keratitis after cataract extraction with clear corneal incision can occur in a patient with rheumatoid arthritis, caution is necessary to minimize damage by careful manipulation during the operation and requires special attention in preoperative and postoperative management.
