We present six patients who were referred after undergoing excimer laser surgery and subsequently required penetrating keratoplasty (PKP) to correct complications of the initial surgery. The excimer laser procedures included 5 cases of astigmatism and 1 case of hyperopic correction. All cases had complications, which decreased visual function and could not be corrected by non-surgical methods. Five cases had severe corneal haze and one case had an acute perforation following excimer laser surgery. After PKP, all patients had a best-corrected visual acuity (BCVA) which varied from 20/30 to 20/20. Awareness of potential complications, which need PKP after excimer laser surgery, is necessary.
