IOP pressure after dialation

 For the last few months, I was keeping my pressure down around 17/18 without using my xalatan. However I went to the doctor the other day and he dialated my eyes ( I hate dialation) and my eyes were feeling a little funny so I went and checked the pressure today and it was 22/23 so I used xalatan tonight.  Has anyone else experience  increased IOP pressure after dialation?
