Is it normal to continously go from clear to blurry vision with toric contact lenses?

Question

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?

Answer 1

Sounds like the lenses are maybe rotating more than they should and going off axis at times when you blink .

Torics are very difficult to diagnose what the problem could be without actually seeing them on the persons eyes.

Did he switch brands or base curve from what you always had ? If one of those were changed, that opens a whole new can of worms....lol

Your Doc has all the info and what changes he made...there really isn't an obvious solution that can be found without actually seeing them and knowing the history.

There ya go...changing the axis 20 or 30 degrees looks like the culprit. Most likely the lenses don't center well anymore and rotate to a wrong axis now.  But they should be able to see that while you are wearing them on your follow up visit...
