[souffle]

what substrate is he on? Could he be a bit allergic to it and it is causing some eye irritation? May be worth trying a alternative to see if that helps. I would keep up the bathing maybe twice a day and would add a pinch of salt to the boiled cooled water as an eye wash. Sometimes hammies can get blocked tear ducts leading to the crusty eyes or possible a previous damage or infection can cause changes in the tear production also leading to the sticky eyes. If he shows any other symptoms though I would have hime seen again at the vets.
