Abstract :
Background: Mitomycin–C (MM-C) is an alkylating anti-tumor antibiotic, which interrupts DNA replication and
inhibits routine synthesis and cell mitosis. This study was undertaken to evaluate the effect of MM-C on the
epithelial ingrowth which is a sight threatening complication after corneal surgeries.
Methods: This study was conducted on 50 corneas of 25 Dutch Albino rabbits. Lamellar keratectomy was performed
and after the application of MM-C 0.02 % or balanced salt solution (control group), the epithelial cells were
implanted on the stromal bed. After sixty days, light microscopic exam was performed on the excised corneas.
Results: Three eyes in the MM-C group and no eye in the control group showed epithelial cell growth under the
corneal flap.
Conclusion: In this study, application of MM-C 0.02% drop at the time of operation had no preventive role in the
corneal epithelial cell proliferation under rabbit’s corneal flap. So, implantation of the epithelial cells under the
corneal flap is not the sole causative factor of epithelial ingrowth in the stroma of the rabbit’s cornea.
