Results of therapeutic penetrating keratoplasty.
OBJECTIVE
By a retrospective study of patients in the Ankara Hospital Eye Clinic, to determine the anatomical and visual results of therapeutic penetrating keratoplasty (PK) and its role in the management of corneal disease.


METHODS
Therapeutic PK was performed in 36 patients (37 eyes) who had corneal perforation due to corneal disease (23 eyes) or eyes in which perforation was imminent (14 eyes). Initial indications for grafting were nonperforated descemetocele without inflammation (six eyes, 16.2%); nonperforated bacterial corneal ulcer (five eyes, 13.5%); nonperforated herpetic keratitis with active stromal inflammation (two eyes, 5.4%); acanthamoeba keratitis (one eye, 2.7%); perforation due to herpetic keratitis (13 eyes, 35.2%); perforation due to persistent epithelial defect (8 eyes, 21.6%); or perforation due to bacterial corneal ulcer (two eyes; 5.4%). The results were evaluated for each of the following criteria: anatomical integrity of the eye, cure of the disease, complications, graft clarity, and visual acuity.


RESULTS
Anatomical integrity was achieved in 21 of the 23 eyes (91.3%) perforated from corneal disease. Therapeutic PK cured the disease in all bacterial keratitis cases. The proportion of clear grafts was 60.9% in the 23 eyes perforated from corneal disease, and 57.1% in the 14 eyes in which perforation was imminent. Fifteen eyes (40.5%) obtained a final visual acuity of 20/100 or better; five of these eyes were not yet perforated before the PK.


CONCLUSIONS
Therapeutic PK is effective in the management of the eye with active uncontrolled infection or perforation from corneal disease. Approximately half of our patients maintained a clear graft at the last visit. Without therapeutic surgery, these eyes would have been lost.
