Abstract
Aim: The aim of this study was to describe the management of two cases of perforated peripheral ulcerative
keratitis (PUK-Mooren’s ulcer) with iris prolapse by using dried sclero-corneal patch graft and subsequently
replacing donor sclero-corneal patch graft.
Methods: After sectoral conjunctival resection, ulcer margin excision, and prolapsed iris excision, preserved dried
sclero-corneal tissue is fashioned, and patch grafting is done as an emergency. After getting the donor sclerocorneal rim, it was again fashioned (matching the size and removal of Descemet’s membrane) and replaced the
dried scleral patch graft followed by a bandage contact lens.
Results: Eleven to 16 months after their initial evaluation, these patients still had some useful vision and selfsatisfaction.
Conclusion: A dried sclera-corneal patch graft could be a satisfactory option in the temporary management of
perforated PUK with iris prolapse until donor tissue is available. This patch graft prevents hypotony, posterior
synechiae, and secondary glaucoma.
