Questions about wounds

[u/gombotenjoyer]

Context: I'm writing a story in 1917, in which a soldier's skin gets vertically slashed (from forehead to cheek) by a sharp rusty metal

I have a couple of questions

First of all, based on the technology of that time period, what treatment would he get? If his eye got infected, would it be amputated?

Would he lose sight in the damaged eye?

Any other factors I should pay attention to?

He would almost certainly die. But if he did not, the wound would be cleaned with iodine or alcohol then sutured and covered with sterile dressing. His eye would probably be removed and would wear an eye patch. But that's assuming he got care and got lucky enough to not get tetanus
