Abstract
Objectives
To investigate the effects of subconjunctival injectable platelet-rich fibrin (i-PRF) injection on healing and complication rates after pterygium surgery with conjunctival autograft.
Methods
This retrospective and comparative study evaluated 31 eyes that received i-PRF injections under the donor and graft conjunctiva following pterygium surgery, while 34 eyes did not receive i-PRF after the pterygium surgery. The patients’ follow-up period was for 12 months. Postoperative recurrence, epithelial healing time, postoperative pain score, graft edema, and sliding of the graft (need for re-suturation) data were evaluated.
Results
For the 12 months after surgery, one eye (3.2%) in the i-PRF group had developed corneal recurrence, and five eyes (14.7%) in the non-i-PRF group had developed recurrence. The mean corneal epithelial healing time was 2.96 ± 0.70 days in the i-PRF group and 3.58 ± 0.70 days in the non-i-PRF group (p = 0.001). The mean healing time of the donor conjunctiva epithelium was 3.84 ± 0.70 days in the i-PRF group, whereas it was 4.44 ± 0.74 days in the non-i-PRF group (p = 0.006). The mean postoperative pain score was 4.45 ± 1.52 in the i-PRF group and 5.08 ± 1.40 in the non-i-PRF group. In the non-i-PRF group, three cases (8.8%) required re-suturation, whereas, in the i-PRF group, no one required re-suturation.
Conclusions
Thanks to its platelets-derived growth factors, i-PRF can be a safe and effective adjuvant therapy for faster healing of conjunctival autograft and in the prevention of recurrence.
