Purpose: To report the incidence of postoperative infectious keratitis after laser in situ keratomileusis (LASIK). Methods: A retrospective study was performed on 12,259 eyes of 6,130 patients between the ages of 18 and 81 who underwent LASIK from July 1996 to August 2002. Slit-lamp examination and/or corneal cultures were performed on all eyes with suspected infectious keratitis postoperatively. All patients had at least one month of follow-up. Results: Six eyes developed clinical signs of infectious keratitis (0.05%). There were 4 cases of bacterial keratitis based on clinical or laboratory findings. Three cases were small peripheral infiltrates presenting 7 days, 12 days, and 4 months after LASIK. One case was a corneal ulcer that developed 76 days post-LASIK. Two eyes developed herpetic keratitis 7 months and 22 months after surgery. There were no fungal, atypical mycobacterial, or protozoan organisms isolated. No patient lost more than one line of vision. Conclusions: In this series of consecutive LASIK cases, the incidence of infectious keratitis is extremely low. The only organisms isolated were bacterial and viral, and the visual outcomes were in general good.
