title: [Comparative analysis of the donor cornea quality and of the interval between death and preservation before and after new sanitary and technique rules in a University Eye Bank].
abstract: OBJECTIVE
  To compare the interval between death and enucleation (ΔT-O-E), between enucleation and preservation (ΔT-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 implementation new sanitary rules.
  
  
  RESULTS
  An increase was observed in the absolute number of 205 to 374 donors following the adopted changes. There was no statistically significant difference in Δt-O-E and ΔT-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 grading of donor cornea quality from 1.76 ± 0.90 to 1.94 ± 0.88 after the implementation of new standards of resolution.
  
  
  CONCLUSIONS
  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 ΔT O-E and ΔT E-P. Cornea quality presented itself lower after the new rules.
