  • Publication number: 20100191177
    Abstract: Surgical devices are provided for aspiration of the subretinal fluid (SRF) of the eye in a retinal detachment that allows re-apposition of the sensory retina to the underlying RPE. The device is connected to a vacuum source, introduced into the posterior chamber through a sclerostomy port and placed against the detached retinal tissue. The device pulls on and captures the surface of the sensory retina, causing a micro needle to pierce through the tissue. As the sensory retina is captured and held in place by the vacuum, a protected pocket is created and the tissue is prevented from folding onto itself and occluding the micro needle tip.
