Pterygium is a fibro vascular encroachment of the conjunctival tissue on to the cornea, causing variable degree of ocular morbidity. Various surgical modalities have been developing to decrease the recurrence. The idea of study is to compare the relative efficacy of two well known procedures i.e. conjunctival autografting and intra-operative Mitomycin – C (0.02%) with reference to recurrence and complication rate.
