Surgeries were performed under local anesthesia and the Pterygium was excised up to the medial rectus muscle. Conjunctival stem cell graft was taken from the suprotemporal limbus of the same eye and stitched with 10/0 nylon onto the pterygium area. Dressing was removed after three days and topical antibiotic with steroid drops were started. Patients were then called for regular follow ups till six months. All the information was collected through a proforma. Results: 85 selected eyes were operated upon using uniform surgical technique. No recurrence was noted in 80 eyes (94.11%) while 5 eyes ( 5.89%) showed recurrence of pterygium.
