Background
 Currently Micro-Incisional Cataract
Surgery Techniques are gaining field
against traditional ones.
 Both, Micro-Coaxial & Micro-Biaxial are
showing advantages in particular in
fluidics.
 A debate exist between promoters of
each technique regarding the
advantages and disadvantages.
Objective & Type of Study
 To determine which
Micro-Incisional
Cataract Technique
utilizes less amount
of irrigation inside the
eye.
 Comparative,
prospective,
randomized study
between MicroCoaxial & MicroBiaxial techniques.
Material & Methods
 50 eyes of uncomplicated senile cataract were
operated by the same surgeon and divided in
two randomized groups.
 25 were operated with Micro-Coaxial technique
(1.6 mm incision); Oertli Phaco System and
passive infusion.
 25 were operated with Micro-Biaxial technique
(0.7 mm incision); Accurus Phaco System and
forced infusion.
 The amount of total Intraocular Saline Solution
was measured in all cases, and both groups
were compared.
Forced Infusion
Internal Forced Infusion created with the Accurus Surgical System
Active irrigation through a 25G cannula
Results
 The Micro-Coaxial
group used an
average of 69 cc in
the entire procedure.
 The Micro-Biaxial
group used an
average of 42 cc in
the entire procedure,
including I/A.
Results
 The Micro-Incisional
Technique that
utilizes less amount
of Intraocular
Solution during the
entire surgery was
Micro-Coaxial
 The differente has
statistical
significance.
Results
Bottle starting a Micro-Biaxial case
Bottle ending the same case.
Discussion
 As much as the
amount of infusion is
lower in the anterior
chamber, less
trauma over the
endothelial cells is
obtained.
Discussion
 Further studies are
needed to determine
the exact
significance of less
irrigating volume in
the postoperative
state of the cornea.
