Results:
Of 789 penetrating keratoplasties that were performed between January 1996 and August 2006, 15 eyes (1.97%) of 14 patients had traumatic wound dehiscence. Eleven eyes were operated for keratoconus, 3 eyes had trachoma, and one had corneal graft for a traumatic scar. The mean time from penetrating keratoplasty to trauma was 33 months (range 2 weeks to 16 years). The mean age at time of wound dehiscence was 37 years (range 18–81 years) with a bimodal distribution (12 eyes between years 11 to 40, and the remaining 3 eyes between years 60 to 90). Falls (46.6%) and playing accidents among children (40%) were the most common mechanism of trauma. Home (80%) was the most common place for trauma to occur. All corneal ruptures occurred at the graft-host interface. There was no particular location preference for wound rupture. Vitreous and lens loss were noted in 11 eyes (73%) and retinal complications occurred in 3 eyes (20%).The first surgical procedure included primary wound closure in all eyes, combined with anterior vitrectomy in 7 eyes, and posterior vitrectomy in one eye. A second surgical intervention for retinal complication was needed in 3 eyes. Eight grafts remained transparent, 2 grafts remained edematous, 4 eyes were re-grafted, and one eye was re-grafted twice. One eye had phthisis. After one year of follow-up, the mean loss of BCVA was 5 lines, one patient had light perception, and 2 patients had no light perception.
