I have the DMV Ultras and they're a bit hard to work. I find putting a drop of saline solution makes them work instantly. If you have Scleral lenses, you can also try to use suction cup on the edge of the lens. The torque pulling from the edge allows the suction cup to break the lenses' seal with less force than trying to pull them out from the center.
I use those to put them in but I cut the tip of the bottom off so there isn't any suction. I use these for removal.
