Intrascleral 30 Gauge Needle Flanged Haptic "Yamane" Secondary Lens Technique

Here Dr. Robert Courtney of Colorado Retina Associates and I show our first attempt at the intrascleral flanged haptic technique of scleral fixating a secondary lens. This technique overall is pretty simple if you follow the technique of Shin Yamane that was presented at the 2016 ASCRS. This patient had an in-the-bag lens/capsule dislocation into the vitreous cavity. Previously we had moved the lens into the AC, bisected it, and removed it through the corneal wound. In previous secondary lens cases, we had done goretex fixated akreos AO60 lenses but that required conj dissection and larger sclerotomies, while this has no conj dissection which makes it simple. The lens is also hydrophobic which should make is compatible with DSAEK while still maintaining a 3mm cornea wound unlike the CZ70BD. Our lessons learned were to make sure the the haptic is fed down the lumen of the 30g needle at least 5 mm to ensure easy externalization. Here we used the EC3-PAL with the Aaren Scientific injector and cartridge along with TSK 30 g needles from Japan. 25g MST forceps are used but 23 g would work as well. Low temp cautery is used to make the flange. Thanks to Steve Safran and Jason Jones for their advice before attempting this procedure.
