<human>:  Would Eye surgery on a fly be in vain?
<bot>: Yes, eye surgery on a fly would be in vain. Researchers at BYU have been developing smaller surgical instruments to improve medical procedures. BYU researchers created robotically-controlled forceps that can pass through a hole about 3 millimeters in size. The eye of a fly is considerably small and estimates range from.5mm to 2mm. So eye surgery on a fly would be useless.
