Penetrating Keratoplasty Following Thermokeratonlasty

We analyzed the long-term results of penetrating keratoplasty following thermokeratoplasty in 17 eyes, and these were compared with 44 eyes in which penetrating keratoplasty was the primary procedure. There was a greater incidence of graft rejection in the TKP group than in the non-TKP group although this difference was not statistically significant. A definite causative factor for this discrepancy could not be identified. Mild inflammatory reaction in TKP-treated corneas and the generally poorer prognosis in corneas needing TKP may be the causative factors for the greater number of failed grafts in the TKP group.
