Even if there is a retained cap, don't bother trying to remove it. Keep your husbandry right and it will come off next shed. Some people freak out and want to get it off right away, but there is risk of damaging the eye and it will not bother the snake if it stays on until next shed. Keep humidity a little higher than normal and it might work the cap off itself anyways. If it's too much to keep overall humidity up, put some sphagnum moss in the hides and keep it damp.
