Retained Eye-caps

[CanadianEryx]

Aside from my ksb's first shed, she has always retained her eye-caps (and she has been shedding on and off for six weeks due to stress and being clawed by a cat). The last time I helped her out with a few drops of contact lens solution and gently pulling the skin off around her head with tongs. Is there a better or safer way of doing this? (I don't even attempt to help her unless she has retained the caps over two or three sheds)
