In cases of insufficient zonular support, using a flange technique has become popular after Dr Shin Yamane shared his technique a few years ago. There are other options besides creating the flange on the haptic itself: 6-0 prolene suture can be used in order to create additional support for good long-term stability and centration of the IOL.
In this video, Dr. Ori Mahler from Israel shows us three different cases where there is a single flange support, a double flange support, or even four flanges for supporting a dislocated IOL. The single flange using the 6-0 prolene to create an eyelet was described by Dr. Masayuki Akimoto from Osaka, Japan. I was recently in Osaka (and Kyoto) and I was impressed by the surgical efficiency and innovation by these Japanese ophthalmologists.
