[Intelligent phaco--always necessary?]
Purpose:
To assess the need of /P system use in soft cataract
Methods:
prospective study--40 eyes with soft cataract (+/++); surgery with Infinity system, Ozil handpiece; in 20 eyes we used low levels (max 70%) of torsional ultrasound power and IP system; in 20 eyes we used higher levels of torsional ultrasound power without IP system; we assessed: the CME value and the presence of cornela edema.
Results:
In cases with tosional ultrasound only: average value of CME--2.4; maxim value of CME--4.3; all corneas without edema. In cases with torsional ultrasound and IP system; average value of CME--3.6; maxim value of CME--7.2; 4 eyes with decemetic folds in central cornea.
Conclusions:
In soft cataracts is better to not use IP system
