Shin Yamane, MD tells us about his Flanged IOL Fixation technique and 3 key points to make it right
This is a surgery for a secondary IOL implantation with the technique of Flanged IOL Fixation.
In this technique, Dr. Yamane does a flanged of the haptic so it will stay stable in the sclerotomy tunnel. This is a minimally invasive surgery. You insert a 3 piece IOL into the anterior chamber, you insert a 30G needle to externalize the haptic of the IOL by inserting the leading haptic into the needle. Then you insert the trailing haptic into the second needle.
This technique has 3 key points
Positional relation of the wounds (90º from the limbus)
Use two needles (insert both haptics into the needles)
Insertion angle of the needles (two tunnels perfectly at 180º and the incision must be parallel)
