Bimanual versus Coaxial Phacoemulsification

Dr. Zaheer uddin Aqil Qazi (FCPS)

Purpose:
To evaluate the efficiency of Bimanual Phacoemulsification as compared to Coaxial Phacoemulsification.

Method:
A randomized controlled trial that included 160 patients. 80 patients will underwent Bimanual phacoemulsification and 80 patients underwent Coaxial phacoemulsification. Surgical time, volume of fluidics used and clarity of the cornea postoperatively was compared between the two groups.

Results:
The cornea was clearer on post-op day one with coaxial phacoemulsification as compared to the bimanual phacoemulsification. The bimanual phaco group had a statistically significant more total operation time and total amount of irrigation fluid used.

Conclusion:
Coaxial Phacoemulsification is preferred by majority of surgeons and is more efficient as compared to Bimanual Phacoemulsification. Reduction in wound sizes in Coaxial Phaco from 3.2 to 2.7 to 2.2 and now finally to 1.7mm, which is nearly approaching that of Bimanual Phaco, is a single important major evidence suggesting that the preferred choice is Coaxial Phaco pressing technology in its favor

Key Words:
Bimanual Phacoemulsification, Coaxial Phacoemulsification
