My BP had the wrinkled eye thing a while back. At first I thought it was eyecaps also, but then the next time he shed I checked it and it was a complete shed with eyecaps, yet his eyes were still wrinkled.
I tried soaking him to no avail, since you can't really keep his eyes wet. then I tried a damp pillowcase and that didn't work either. Next, I got some sphagnum moss, wet it and stuck it in a bowl inside his tub beside his water dish. this helped , the next time he shed his eyes were back to normal. I guess the extra humidity helped.
When it happened I was starting to get nervous because I was talking to the guy at the reptile store I got him from, and he said if you don't get the eyecaps off and they start to build up the snake could go blind.
I was pretty relieved when his next shed came and went and his eyes were fixed.
