Patent attributes
An apparatus and minimally invasive method for removing fluid from a subretinal space to allow a detached retina to flatten. An apparatus, comprising a fluid withdrawal device and a guide for advancing and placing the device, is positioned on the exterior eye surface at the detachment site. Various embodiments of the apparatus are disclosed. Using the guide, the surgeon advances the device into the fluid-filled space and drains fluid, allowing the retina to flatten. Additional injection of saline or gas into the vitreous cavity normalizes intraocular pressure, and the patient is ambulatory immediately afterward. Unlike other retinal attachment techniques, in the inventive procedure the patient receives only a local anesthetic, and has no restraint on head movement.
