- The one Delta Shift guy has an eyepatch? Guy likes Martok? Is skipping over a replacement allowable in Starfleet? IT's an EYE, but the segment ended with cloning a replacement for a non-bleeding leg.
It could be a problem with regenerating the optic nerves. Star Trek has had episodes where they can't fix certain nerves so Delta Shift guy and Martok's eye might no longer be replaceable even with a device.
