Materials and Methods: This retrospective study included 43 eyes of 43 patients who developed perforated infectious corneal ulcer of various etiological causes between June 2008 and January 2018. The patients were evaluated based on age and sex, follow-up time, presence of corneal perforation, pre- and postoperative visual acuity, postoperative graft transparency, complications, and infection recurrence. Results: The mean age of the 43 patients was 52.9}13.8 years. The mean follow-up time was 2.7}1.3 years. Preoperatively, the visual acuity of the eyes was at the level of hand motions or counting fingers; postoperative best corrected visual acuity ranged from hand motions to 0.7. Postoperative complications included hyphema in 8 patients (18.6%), elevated intraocular pressure in 14 (32.5%), posterior synechiae in 18 (41.8%), and cataract in 22 patients (51%). Therapeutic and tectonic success was achieved in 42 patients (97.6%). Postoperative graft transparency was observed in 35 patients (83.3%) within the 1-year follow-up period and in 27 patients (71.0%) at 2 years. Among 27 patients with graft transparency, 23 had bacterial and 4 had viral etiologies (p=0.52); 16 patients had perforations smaller than 1 mm and 11 had perforations 1-3 mm in size (p=0.2). Conclusion: Therapeutic-tectonic keratoplasty for perforated infectious corneal ulcer successfully restored globe integrity in 97.6% of cases. The rate of graft transparency was 71.0% at 2 years, with no effect of etiological agent or perforation size
