Brief Summary

Ologen implantation with conjunctival autografting shows promising results in surgical management of recurrent pterygium comparable to MMC application with conjunctival autografting with mild non vision threatening postoperative complications.

Outcome Measures

Primary Outcomes (2)

  • 32 eyes with Topical application of Mitomycin C in concentration of (0.2 mg/mL).

    As for group A, 0.2 mg/mL MMC was prepared by reconstituting 2 mg vial of Mitomycin with 10 mL sterile water for injection. When using Mitomycin 10 mg vial, the same concentration was achieved by reconstituting the 10 mg vial 10 mL sterile water for injection. Then 1 ml of the prepared solution was diluted with 4 ml of saline to achieve 0.2 mg/mL (0.02% solution).

    "through study completion, an average of 1 year".

  • 31 eyes with ologen implantation(6 mm in diameter and 2 mm thick.) was used for each patient.

    In group B; Ologen was applied under the graft tissue once it is secured in place (half the vial is used for every patient)

    "through study completion, an average of 1 year".
