Yamane technique for dislocated IOL: Intrascleral Haptic Fixation - Dr Simon Chen

Surgical video showing a dislocated intraocular lens (IOL) on the retina being repositioned with vitrectomy surgery and intrascleral haptic fixation using a double needle technque with flanged haptics (Yamane technique). A 38 year old man reported poor vision due to dislocation of an intraocular lens onto the retina. Uncorrected Visual Acuity preop = Counting Fingers only Cataract surgery had been performed 10 years ago for a juvenile cataract. 1 month prior to this presentation, the IOL had spontaneously subluxed out of the capsular bag and was treated with surgical repositioning of the haptics into the sulcus and the optic behind the anterior capsule (optic capture) with a good initial result. However, the IOL subsequently dislocated completely into the posterior segment. Surgery consists of a 25g vitrectomy with repositioning of the IOL (an Alcon MA60AC 3 piece acrylic IOL) using 25g forceps and the distal haptic technique. The IOL is fixated to the sclera using Yamane's double needle technique with loop cautery to mould the haptic tips into terminal flanges/bulbs. At day 4 post-op, the uncorrected visual acuity was 6/6 (20/20) with a stable well positioned IOL. Surgery performed in 2016 by Dr Simon Chen, Vision Eye Institute, Sydney, Australia. http://www.visioneyeinstitute.com.au/...
