9. CONCLUSION ULTRACHOPPER AND MECHANICAL CHOPPER WERE EFFECTIVE AND SAFE IN THE PHACOEMULSIFICATION OF BRUNESCENT CATARACTS.ULTRACHOPPER AND MECHANICAL CHOPPER WERE EFFECTIVE AND SAFE IN THE PHACOEMULSIFICATION OF BRUNESCENT CATARACTS. ALTHOUGH THE ULTRACHOPER GROUP NEEDED MORE ENERGY AND BSS USE (STATISTICALY SIGNIFICANT), IT DID NOT INFLUENCED DIFFERENCES IN CORNEAL PACHIMETRY OR ENDOTHELIAL CELL LOSS AT 6 MONTHSALTHOUGH THE ULTRACHOPER GROUP NEEDED MORE ENERGY AND BSS USE (STATISTICALY SIGNIFICANT), IT DID NOT INFLUENCED DIFFERENCES IN CORNEAL PACHIMETRY OR ENDOTHELIAL CELL LOSS AT 6 MONTHS ULTRACHOPER WAS SAFE AND EFFECTIVE FOR PHACO OF BRUNESCENT CATARACTSULTRACHOPER WAS SAFE AND EFFECTIVE FOR PHACO OF BRUNESCENT CATARACTS AGUILERA MD
