Análise da qualidade das córneas doadas e do intervalo entre óbito, enucleação e preservação após a implantação de novas normas técnicas e sanitárias em

ABSTRACT Purpose: To compare the interval between death and enucleation (∆T-O-E), bet ween enucleation and preservation (∆T-E-P) and the quality of the cornea before and after the implantation of new technique and sanitary rules. Methods: A retrospective study that evaluated the records of cornea donors in Sao Paulo’s Santa Casa Eye Tissue Bank 2 years before and 2 years after the implementa-tion new sanitary rules. Results: An increase was observed in the absolute number of 205 to 374 donors fol lo- wing the adopted changes. There was no statistically significant difference in Δt-O-E and ∆T-E-P before and after the implemented changes. Of the total of 1,105 donor corneas, 388 donor corneas were observed before the changes and 717 donor corneas after the implemented changes. We observed a statistically significant increase in gra-ding of donor cornea quality from 1.76 ± 0.90 to 1.94 ± 0.88 after the implementa tion of new standards of resolution. Conclusion: After the changes required by Resolution 347, there was a large increase in the number of donated, taken and preserved corneas. The BTO has not diminished the ∆T O-E and ∆T E-P. Cornea quality presented itself lower after the new rules.
