This unique design provides a tip that is efficient for chopping as well as manipulating the nucleus without endangering the posterior capsule. Lesieur Hydrochopper is developed specially for Bimanual Microphaco. 20 Ga tip with Nagahara type chopper (for 1.00 mm incisions). The end opening port provides maximum irrigation. The dual oval side ports 0.50x0.70 mm provide supplemental irrigation in case when the front opening is overfilled.
