Penetrating keratoplasty after excimer laser surgery.

ABSTRACT

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.
