Surgical Detachment of the Anterior Hyaloid Membrane From the Posterior Lens Capsule

Abstract

Purpose: To describe 2 techniques facilitating the potentially challenging removal of the anterior hyaloid during phakic pars plana vitrectomy. Methods: Observational surgical series describing the 2 techniques. The hydrodissection technique applies an injection of balanced salt solution into the anterior chamber to displace the anterior hyaloid posteriorly for facile removal. The bubble technique is a novel method that utilizes air bubbles to visualize the anterior vitreous, allowing closer placement of the vitrectomy cutter to facilitate anterior hyaloid removal. Results: Both techniques were successful for the safe, efficient removal of the anterior vitreous. Conclusion: Removal of the anterior vitreous in a phakic patient is a difficult maneuver which may lead to potential damage to the lens. The hydrodissection and bubble techniques may be used to efficiently and safely remove the anterior vitreous.
