Radial and transverse keratotomy are procedures frequently used to correct myopia and/or astigmatism. However, postoperative complications may occur.1 Microbial keratitis may result from epithelial defects created by the surgery. This is particularly true in the presence of preoperative adnexal infection. We describe the first reported case, to our knowledge, of bilateral bacterial keratitis in a patient who underwent radial/transverse keratotomy on both eyes within a 24-hour period.

Report of a Case.  —Preoperative cycloplegic refraction in a 52-year-old man was -9.25 +2.00 axis 164° OD and -8.50 +2.75 axis 180° OS. The best corrected visual acuities were 20/40 OD and 20/50 OS. Both eyes underwent refractive keratotomy within 1 day of each other. The surgical parameters included a 3-mm-diameter clear zone and eight radial centripetal incisions with the diamond blade set at 110% of the thinnest pachometry reading. Nonconnecting paired transverse incisions were made in the 180° meridian in each
