Abstract
The goal of the bimanual sleeveless phaco technique is heat reduction and the elimination of corneal bums. At reduced heat, water is no longer needed to cool the phaco tip, so one can break down the infusion and aspiration emulsification instrument into two hand pieces rather than one, with the net result of two microincision.
The potential advantages of microincision phaco include a tightly closed system with the ability to use irrigation flow as a manipulation assistant to move lens material to the phacoemulsification tip rather than to push particles away. Other advantages are the ability to switch the phaco needle from one incision to the other when the nucleus is not rotating appropriately. In addition, preventing irrigation from short¬circuiting and flow back into the aspiration port by eliminating the coaxial irrigation sleeve may improve efficiency.
Evolving IOL designs for incisions smaller than. 2.00 mm will accelerate the acceptance of microphacoemulsification. Until these IOLs are proved save and effective, switching to this technique from coaxial phaco is still controversial.
In this study, 50 eyes of 35 patients with immature senile cataract ranging from grade I to grade 4 were divided into two groups.
