Purpose To compare the efficacy, safety and recurrence rate of platelet‐rich fibrin (PRF) grafts and limbal conjunctival autografts (LCAs) following pterygium excision. Methods A total of 108 patients (108 eyes) with primary pterygium were included in this study and were divided into group A (56 eyes) and group B (52 eyes). Patients in group A underwent excision of the pterygium followed by LCA while patients in group B underwent PRF grafts following pterygium excision. The PRF was produced using the patient's own whole‐blood sample by centrifugation and extrusion. The surgery time, intraoperative complications, postoperative complications, recurrence rate, intraocular pressure (IOP) and follow‐up period were recorded and evaluated between the two groups. Results The mean surgery time was significantly shorter in group B (25.0 ± 4.2 min) than in group A (36.5 ± 6.3 min) ( P < .001). Recurrence was observed in two cases (3.6%) in group A while no recurrence was observed in group B. No graft loss was observed in either group. No other intra/postoperative complications such as a tear in the graft, injury to the medial rectus muscle, excessive bleeding, scleral necrosis, graft oedema, graft necrosis, pannus formation or symblepharon appeared in either group. Conclusions This study presented with a promising outcome of PRF graft applications in primary pterygium surgery. The use of PRF following pterygium excision is a simple, easily applicable, and comfortable method for both patients and surgeons, with less time consumption, recurrence rate and complications, which could be widely used in pterygium management.
