Abstract Details


To report intermediate term complications on a longer term follow up of an initial experience in a consecutive series of 30 cases of pterygium excision done with the wet amniograft and comparing this to a similar series of dry amniotic membrane graft with a 180 day follow up.


A clinical private practice setting. A retrospective study.


30 consecutive cases of amniograft(prokera) were performed under sub tenon lidocaine 2% with epinephrine anesthesia. A pterygium excision was performed using a standardised technique and a wet amniograft was anchored on the scleral bed using fibrin tissue glue. A bandage Contact lens(CL) was used in the wet graft cases only. Patients were examined post-op day 1 or 2, day 5 to 8 and then week 2,4,8 and additional days in between if clinically deemed necessary


No graft displacement occurred after the initial post-op period in either group. Post op regimen included CL use in the wet group but not in the dry group. Conjunctival vascularisation was noted respectively in 9 eyes with 2 recurrences in the dry group and 4 with 1 recurrence in the wet group. Durezole was used in 12 eyes in the wet graft group only


The wet bio-tissue graft has lesser intermediate complication rate in this initial small group performed by an experienced surgeon. FINANCIAL INTEREST: NONE
