I have to agree with Dmurray1031 Law was able to do this using his devil fruit powers and haki (right before he slices Vergo he is seen "preparing" to use room with his hand). From what we have seen of the Ope Ope fruit Law is most likely capable of cutting anything besides seastone unless it has greater haki in it than him. He probably was at full power to insure that he would cut Vergo and he only sliced the surrounding area of that lab, not even the whole frozen side of the island.
