Is It Normal To Continously Go From Clear To Blurry Vision With Toric Contact Lenses?

I’ve been wearing toric contact lenses for astigmatism for 3 years now. The new eye Dr I saw recently made some changes to the prescription, and now the new lenses cause my vision to go from clear to blurry all day long. Sometimes it will be one eye, then it will be the other, but it never stabilizes. He is certain he got the prescription correct, but this is really annoying. Can something be changed to the Rx (such as the fit) to make my vision more consistant?
