Question about colored contacts, but there is a problem!?

I have a beign abnormality in one of my eyes (right eye) which is a problem with the dilator of the iris. The problem isthat the dialator does not function properly, thus making the right pupil smaller than the left. I believe this is called anisocoria, if I am not mistakened. Well, my question is are there any possibilities out there that can conceal this abnormality in the sizing of my two pupils? I have tried a free trial pair of Freshlook Colorblends, but it did not work well- it actually annunciated the problem. Besides, my normal irises do not have fancy designs on them, and the Freshlook Colorblends do, making them look fake. Are there any solutions to this? Are there colored contacts out there that work well the best and look realistic and maybe a smaller "pupil hole" in the colored contacts?
