IntroductionIntroduction
Phacoemulsification was the technique that was Phacoemulsification was the technique that was
performed in almost all cataract surgery. performed in almost all cataract surgery. When phacoemulsification was first introduced, When phacoemulsification was first introduced,
the nucleus was not divided and the phaco-the nucleus was not divided and the phaco-
emulsification probe was used to sculpt and emulsification probe was used to sculpt and
consume the nucleus. consume the nucleus. Compared with extracapsular cataract extraction,Compared with extracapsular cataract extraction,
phacoemulsification in associated with additionalphacoemulsification in associated with additional
potential risks of corneal endothelial cell damage.potential risks of corneal endothelial cell damage.
PurposePurpose
To compare the intraoperative and short-term To compare the intraoperative and short-term postoperative outcomes of cataract surgery postoperative outcomes of cataract surgery performed with 3 different types of the phaco-performed with 3 different types of the phaco-technique (phaco-chop, divide-conquer and technique (phaco-chop, divide-conquer and stop & chop) under microcoaxial or stop & chop) under microcoaxial or conventional cataract surgery according to the conventional cataract surgery according to the cataract density.cataract density.
