Smaller Incisions - less invasive approach◊ Almost impossible to detect the enlarging of the Main Incision◊ Truly anastigmatic◊ Min. change in corneal shape and elevation◊ Minimal induction of HOA

EVEN THE INCISION WAS ENLARGE FOR IOL INTRODUCTION

BIAXIAL vs MICROCOAXIALADVANTAGES

BIAXIAL vs MICROCOAXIALADVANTAGES

Better maintenance of A.C. with OVD ◊ Making standard Capsulorhexis◊ Capsulorhexis from both incisions◊ Implanting CTR

Less possibility of Iris extrusion◊ Even in Intraoperative Floppy Iris Syndrome (IFIS)

BIAXIAL vs MICROCOAXIALADVANTAGES

Switch hands during the Phaco◊ Instructional for Right and left handed Less BSS consumption The irrigation is a third instrument◊ For mobilize the pieces◊ To protect and push away the posterior capsule

Minimal Turbulence◊Stable A.C. during the whole surgery◊Less endothelial cell lost◊Minimal uveal trauma◊Less mobilization of the vitreous◊Perfect in RLE

◊ Indicated in cases of previous retinal tears or retinal surgery
