Abstract
A method for injecting viscous material into the eye. In the injection into the eye, sufficient material is injected to separate a membrane from the retina so that intraocular scissors may be manipulated between the membrane and the retina to cut the attachment points. The membrane is then aspirated away. The injection is done using a standard glue injector with a one-shot and a continuous mode. The glue injector is pneumatically coupled through a sterile filter and a custom adaptor to a sterile syringe storing the material to be injected.
