The Solution

        
RetinaSense will enable surgical instruments to provide a secondary signal, most likely to be an audible tone, to surgeons to distinguish between touching healthy retinal eye tissue and tissue that needs to be removed. It consists of a hand held, battery operated retinal rake (or other retinal surgical instrument) having two electrodes, wherein at least one electrode is the modified retinal rake. Upon contact with different optical tissues the electrodes detect varying impedances which are translated by on board circuitry into various signals that indicate what type of tissue, fluid and structure is in contact with the retinal rake.The key advantage of this device will be increased surgical precision by sounding a tone when viable retina tissue is being touched maximizing effectiveness of surgery and reducing risk of retinal tear compared to conventional methods. This will minimize complications from surgery.
