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.

3
Objective Type of Study

• To determine which Micro-Incisional Cataract
  Technique utilizes less amount of irrigation
  inside the eye.
• Comparative, prospective, randomized study
  between Micro-Coaxial Micro-Biaxial techniques.

4
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.

5
Forced Infusion
Internal Forced Infusion created with the Accurus
Surgical System
Active irrigation through a 25G cannula
6
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.

7
Results

• The Micro-Incisional Technique that utilizes less
  amount of Intraocular Solution during the entire
  surgery was Micro-Coaxial
• The differente has statistical significance.

8
Results
Bottle starting a Micro-Biaxial case Bottle
ending the same case.
9
Discussion

• As much as the amount of infusion is lower in the
  anterior chamber, less trauma over the
  endothelial cells is obtained.

10
Discussion

• Further studies are needed to determine the exact
  significance of less irrigating volume in the
  postoperative state of the cornea.
