Researchers from Tel Aviv University succeeded in transplanting corneas and 'welding' them into place in the eye - using a smart system based on a laser and an optical fiber

The retina of the eye: the light comes from above and is concentrated by the glial cells towards the light receptors. The glial cells function as optical fibers and separate the incoming light according to its color (in red) before it reaches the photoreceptor layer (in blue)

In the picture: an illustration of a future holographic stimulation system mounted on glasses that will serve as a visual "prosthesis" for the blind. Images from a miniature video camera will be converted in real time into holograms projected by a laser onto retinal cells (at the back of the eye) that have been genetically modified to be sensitive to light.

Cut through the retina. Except for the gray engulfing layers at the bottom, all the parts are transparent and have been painted here for demonstration purposes only. The nerve cells fill the blue volume, and the cell nuclei are pink, brown and red. The light comes from the pupil of the eye (above) and is captured in the funnels of the glial cells (green) where it is concentrated to the color-sensitive cells (membranes) marked in purple. The rest of the scattered light reaches the reed cells that are not sensitive to color (in orange). The thickness of the retina is about a quarter to half a millimeter.
