my friend's 10-18 was severely damaged, it was sent to repairs, he asked me to check if it is repaired well, when checking pictures I noticed the lens can be sharp on both sides but not at the same time, the focus plane is not parallel to the center, it is closer to the left.

so either I use the left AF point and left is sharp right is back focused or I use  right AF right is sharp left is front focused using live view of course, is that decentering ? Naturally  will resend it for repairs, hopefully they will do a good job  this time
