Pseudo anterior capsule barrier for the management of posterior capsule rupture

Abstract

A technique that uses an implanted intraocular lens (IOL) to create a barrier for the management of posterior capsule rupture is described. When a rupture occurs, surgery is halted and a dispersive ophthalmic viscosurgical device (OVD) injected into the anterior chamber to prevent vitreous prolapse. The remaining nucleus is maneuvered into the anterior chamber away from the pupillary space. The posterior capsule tear is converted into a continuous curvilinear capsulorhexis where possible. Dissociated anterior vitrectomy is performed as indicated, keeping the large nuclear fragments trapped in the OVD-filled anterior chamber. An IOL is implanted in the capsular bag or sulcus with optic capture through the anterior capsulorhexis. Using reduced parameters, phacoemulsification of the remaining fragments is completed over the IOL, which functions as a barrier to seal off the vitreous cavity. Residual nuclear fragments and vitreous are cleared from beneath the optic by placing the vitreous cutter under the optic, recapturing the optic before the instruments are removed from the eye.
