Aim: To study the risk factors, postoperative course, and long-term survival of therapeutic PKP.
Design: Prospective case series. Materials and
Methods: 40 patients operated at by single surgeon for therapeutic penetrating keratoplasty. Patients with less than one year of follow up, tectonic, and lamellar keratoplasties were excluded. mostly perforated & Non healing corneal ulcers cases included and Statistical survival analysis was done to calculate median survival time of grafts and to see correlation between variables viz. vascularization, previous failed grafts, lag time between corneal perforation and transplantation, scars, tissue quality, graft size and follow-up.
Results: Median survival of the graft was 22 months. Graft survival was lower in vascularized corneas and in post-perforation corneal scars. Statistical analysis showed that several factors were predictive of graft failure.
Conclusion: Long-term survival of grafts was good even in long lag time of transplantation.
