Abstract Details


To compare the efficacies of straight flattened tip (introduced by Dr. Kishimoto) and angled Celman non-flared tip.


Saint-Petersburg’s Branch of S.N.Fyodorov’s State Institution Eye Microsurgery Complex, Saint-Petersburg, Russia.


33 patients underwent bimanual torsional phacoemulsification. One half of the nucleus was removed using the straight flattened tip, and the other half was removed using non-flared Celman tip. After each hemisphere removal, cumulative dissipated energy (CDE), aspiration time, and the volume of the consumed fluid were measured.


Use of flattened (Kishimoto's) tip was associated with significantly higher CDE and aspiration time, but lower consumption of fluid (p<0.05), as compared with the bent tip.


Motion amplitude of the straight flattened tip is presumably lower than the one of the angled tip. Kishimoto's tip reduces chatter, therefore keeping the nuclear pieces on the tip's bevel; however, it more time and energy are required to aspirate these pieces.
