Had this problem with our argon too. While this won't help if in fact there's an issue with astigmatism (though I presume you did a lot of lasers in training just fine and you had a similar refraction then). Turns out the laser had shifted on the track plus it had other servicing issues. Worth checking out if no one has serviced the laser in a long time. Your partners may have just gotten used to the fact that it is super close.
