Purpose: To determine effectiveness of laser-assisted in situ keratomileusis (LASIK) in the treatment of astigmatismfollowing penetrating keratoplasty (PK). Methods: We performed a retrospective review of medical records of patients who underwent LASIK followingPK and had over 1 year of follow-up data. Results: Twenty-six patients (26 pairs of eyes) underwent LASIK following PK. Mean age of the patients at thetime of LASIK was 40.7 years (range, 26 to 72 years). Following LASIK, the mean cylinder was reduced by2.4 diopters and mean reduction of cylinder after LASIK was 65.4% from the preoperative values at the lastfollow-up visit. Uncorrected visual acuity became 20 / 50 or better in 69.2% of the eyes after LASIK. Best-correctedvisual acuity became 20 / 50 or better in 73.1% of the eyes after LASIK. All of them were intolerableto contact lenses before LASIK. After LASIK, 6 pairs (23.1%) did not need to use contact lenses and 18 pairs(69.2%) were tolerable to using contact lenses or spectacles. There were no significant endothelial cell densitychanges 12 months after LASIK (p = 0.239). Conclusions: LASIK is effective in the treatment of astigmatism following PK and increases contact lens andspectacle tolerance.
