Keratitis after implantation of intrastromal corneal ring segments.
A 53-year-old man had implantation of 2 intrastromal corneal ring segments (Intacs, Addition Technology Inc.) in the left eye. Several days after the lower segment was exchanged, an infiltrate was present at the corneal incision site. This progressed to a lower channel infection followed by diffuse keratitis. Culture from the conjunctiva was positive for Staphylococcus epidermidis, but cultures from the cornea were negative for microorganisms. Later, 2 gas bubbles appeared at the interface. The patient was treated with topical and subconjunctival antibiotics and channel irrigation. The keratitis resolved, leaving a neovascularized opacity at the nasal part of the lower channel.
