RESUMO
Purpose: To prevent the occurrence of secondary cataract after ECCE with PC-IOL implantation and evaluate the safety and effectiveness of Mitomycin C and 5-FU when used intraocular as an irrigating solution for its prevention in rabbits Materials and Methods: 15 rabbits were divided into 3 groups: Group A was given 5-50 mg/ml FU in 500 cc of BSS plus solution; Group B received MMC 0.2 percent mg/ml in 500 cc BSS; and Group C served as control with pure BSS. The study was done in accordance with the guidelines published by ARVO. The investigated drug solution was used as irrigating solution in cataract extraction performed in rabbits. Postoperatively, the rabbits examined under slit lamp from the 1st post op day and every 3 days thereafter. Their globes were enucleated 2 wks post op and 4 weeks post op, and sent to Pathology Laboratory for processing Results: Group A and Group B showed clear posterior capsule with no evidence of epithelial cell migration. Group C showed evidence of minimal to moderate epithelial cell migration and proliferation with fibrosis Conclusion: Mitomycin C (MMC) and 5-FU minimized and even prevented secondary cataract formation, with no effect on ocular structures when used as an irrigating solution.
