Yamane Technique Tips
Part 1:
LOCATION OF THE INCISIONS: Set the incisions on the Slip Lamp to create a virtual “T”. – Main incision at 120-degree
– Left sclerectomy: 90-degree distance from the main one (30-degree);
– Right sclerectomy: 90-degree distance from the main one (210-degree).
NEEDLE SUPPORT: Position the insulin needle inside the eye before injecting the lens. During lens injection, the insulin needle will work as a lens bracket.
DOUBLE LEFT: In this position it is possible to use the left hand to handling the 2 sclectomies and to insert the 2 haptics in the needle with the right one.
MATERIAL: Sensar AR40e, testfine needle or 26G insulin, 23G.

Yamane + Canabrava Ring
Sergio, why Yamane technique in this video instead of 4 Flanged Technique?
The answer is: smal pupil case! In scleral fixation cases that u need any iris expansion ring, in my experience, I suggest Yamane instead of Canabrava’s Technique because the size of the IOL optic zone!

Huge Hipotony
If you work with Scleral Fixation, trust me, one day, you will have this problem! It is a nightmare for us!
Some doctors try knots + visco (OVD), but if you have posterior mainteiner connected, you can just press the incision and your eye will fill like a balloon! I call it “water balloon technique”, but I don’t the right name!
Sometimes it will save your Rhexis.

New Pivot Technique
Tip to avoid Argentinian Flag.
Have you seen this maneuver before? Attention in this kind of case!
If you try to finish the rhexis without the new pivot, the rhexis goes!

Posterior Rhexis
It is a patient with posterior polar cataract. During the plaque removing… Capsule Rupture! What to do?
1. OVD to avoid vitreous loss;
2. 26g needle to create new pivot;
3. Posterior rhexis;
4. OVD again;
5. IOL with captured optic zone.

Artificial Iris
For the first time, a surgeon @stevekmd1 could perform the Canabrava Technique with Artificial Iris.
First, he fixated the Akreos IOL in Sclera using the 4 Flanged technique with Akreos IOL.
Finally, he used the double flanged suture in 3 points to fixate the artificial iris in the sclera. Congratulations Steve! Great Surgery!
This post shows:
– A patient with IOL OPTIC CAPTURED post phacoemulsification in Morgagnian Cataract;
– Example drawing;
– Rhexis size example;
– Three piece IOL recommended to use in the technique.
I recommend to capture the optical zone in patients with:
– Posterior capsule rupture;
– Morganagnian cataract and;
– Large Capsular bag.
IMPORTANT – To capture the IOL optic, the capsulorhexis opening must be at least 1.0 to 2.0 mm smaller than the optic diameter.
ADVANTAGES
– The technique provides stability and long-term centration of the IOL – Prevents vitreous from extending anterior to the IOL in posterior capsular rupture;
– Prevents pigmentary dispersion.
