Kaminari Kagura: the “lightning bolt shape” technique for posterior vitreous detachment induction

Abstract Purpose To describe and evaluate the effectiveness of the Kaminari Kagura technique as a posterior hyaloid detachment treatment. Study design This was a prospective, consecutive, randomized interventional study. Methods This study examined 30 eyes from 30 patients divided into two groups: (1) a Kaminari Kagura group (15 eyes) and (2) a control group (15 eyes) scheduled for vitrectomy with an optical coherence tomography (OCT)-based diagnosis of adherent posterior hyaloid. Results The mean time for posterior vitreous detachment (PVD) induction in the Kaminari Kagura group was 58 ± 6.6 s, and that in the control group was 69 ± 9 s (p < 0.005). No intra- or post-operative complications were reported. Conclusions The Kaminari Kagura technique results in effective posterior hyaloid detachment in less time than that required for posterior vitreous cortex engagement.
