Toric vs Non-Toric

[atulg]

If you wear soft contact lens for KC, what is a better option: Toric or spherical contact lens? I have been using non-toric for many years and I want to try toric recommended by an optician. I actually didn't even know about them before.

I don't think I've ever tried non-toric!

I've tried many different types, and just for your information, found my current lenses: Bausch + Lomb PureVision 2 (for astigmatism) to be the most comfortable.

Thanks for your recommendation. I have just changed doctors and I got a new prescription but the new lens is just not as good as the old one in terms of vision quality. I am now trying to determine how the doctors come up with the soft spherical lens number based on the prescription. Can somebody please post their prescription details and the lens number that they wear.

It's often said that prescribing contact lenses for KC is more than an art than a science. There is a lot of trial and error involved in obtaining an optimum prescription for contact lenses. Which can be incredibly frustrating. If your old prescription is not as good as your old one go back to the optician and explain your problem. Be aware that sometimes a comfortable lens with good vision can be an unhealthy fit so should no longer be worn (although this probably applies more to RGPs than soft lenses).

Prescriptions for contact lenses are quite different from those for glasses. My right eye is -13.00 sph - 1.75 cyl but my RGP is -10.25.

You may also find it useful to view a couple of videos by optometrists talking about KC and contact lenses.
