Surgically induced detachment of the anterior hyaloid membrane from the posterior lens capsule

Vitreous hemorrhage adhering to the posterior lens capsule prevents adequate visualization of the vitreous cavity and fundus during vitreous surgery and during the dissection of fibrovascular membranes. This type of hemorrhage is difficult to remove by aspiration or resection using a vitreous cutter. We have developed a new technique designed to detach surgically the anterior vitreous for the removal of hemorrhage in patients with proliferative diabetic retinopathy. In this hydrodissection technique, the anterior vitreous is detached from the posterior lens capsule by a forced injection of infusion fluid into the anterior chamber. This technique separates the vitreous hemorrhage adhering to the posterior lens capsule and allows its removal.
