Anisimova NS, Arbisser LB, Shilova NF, et al. - In this prospective, non-interventional, single-center study, researchers confirmed the presence of incomplete vitreo-lenticular adhesion through microscope-integrated intraoperative optical coherence tomography (iOCT) during cataract surgery and postoperatively through diagnostic spectral-domain OCT. Clinical features and surgical videos have been recorded for 27 patients (28 eyes) who underwent cataract surgery. The posterior capsular rupture has been transformed into a posterior capsulorhexis, leaving intact the anterior hyaloid membrane. According to findings, iOCT verified the penetration of micro-fragments of the crystalline lens, cellular material or medical suspension (triamcinolone application) in the space between the posterior lens capsule and the anterior hyaloid membrane. This is because both lenticular zonules and Wieger's ligament attachment are discontinuous. A Wieger's ligament rupture may also allow excessive Berger's room hydration during phacoemulsification resulting in anterior displacement of the posterior lens capsule increasing the danger of instrument contact and posterior capsule rupture.
