A 65- year old male presented with a reddish mass in left eye with diminution of vision for past four months. Based on clinical examination, a probable diagnosis of ocular surface squamous neoplasia with mature cataract was made. Excision biopsy of the lesion demonstrated intraepithelial neoplasia involving cornea and conjunctiva. Post-operatively patient was put on topical mitomycin –C (0.01%) eye drops 4 times a day for 12 weeks. Cataract surgery was done in the same eye 3 months after cessation of topical Mitomycin-C (MMC) treatment. Follow-up was done for 18 months. Patient’s vision improved to 6/9 in left eye.
