Background: 870 eyes of 855 patients with intumescent immature and total white cataract were enrolled in this retrospective clinical study (2013-2018). Methods: Through a side port using a 25 gauze round/flat tipped fine cannula connected to a 5ml syringe (after a nick being created by a regular 26 gauze cystitome) the free capsular flap was vacuumed by the tip of the 25 gauge cannula and suction pressure created by withdrawing the piston of the syringe and a controlled motion done to create a circular rhexis, without withdrawing the instrument from anterior chamber and aspirating liquefied cortex by the same cannula. All cases were done under peribulbar anesthesia. Results: A complete cannula vacuum continuous curvilinear capsulorhexis (CanVac-CCC) was achieved in 860 cases (98.85%) except eight cases (0.91%) which had anterior capsular rhexis extension and two cases (0.22%) which had also extended posterior capsular tear. Conclusion: Performing CanVac -CCC with our technique is safe and affordable and may be an alternative promising method to routine CCC by using 26 gauge cystitome, Utrata or microrhexis forceps.
