Material and Method: Thirty-five eyes of 35 patients who underwent tectonic PK between January 2000 and January 2017 were included in this study retrospectively. The cases were evaluated in terms of age, sex, etiology, follow-up period, anatomical stability, graft clarity, best corrected visual acuity and complications. Results: Twenty-one of the 35 patients were male. The mean age was 49.4. The mean follow-up period after keratoplasty was 43.2 ± 8.4 months. Predisposing factors leading to perforation were microbial keratitis in 17 eyes (48.5%), corneal melting associated with ocular surface disease in 13 eyes(37.1%) and perforated descemetocele in 5 eyes (14.4%). Anatomical stability was achieved in 94% of the eyes. The graft clarity rate was 62% at the end of the follow-up period. Approximately half of the cases obtained a final visual acuity of 0.2 and better postoperatively. The most common complication was glaucoma. Discussion: Emergency PK is required to maintain anatomical integrity in corneal perforations. Success rate is evaluated with anatomical integrity; graft clarity and visual acuity are not satisfactory. However, prognosis can be improved by the control of the underlying pathology, inflammation and intraocular pressure.
