If I have scarring on my cornea from contact lens use but my vision is 20/20 with squinting--is this serious?

If I have scarring on my cornea from contact lens use but my vision is 20/20 with squinting--is this serious?

Corneal Scarring: The front clear layer of the eye is the cornea. It must be clear to let a clear image into the eye. If the retina receives a clear image & everything is normal then the brain should see the image/picture clearly, such as 20/20 vision. Damage anywhere along the way from the cornea to the brain can prevent us from seeing clearly. Scarring on the side is "ok" but in the center will block your vision ...Read more

In Fuchs dystrophy, will contact lenses make symptoms worse because the cornea is getting less oxygen. I really don't want to give up wearing contacts?

In Fuchs dystrophy, will contact lenses make symptoms worse because the cornea is getting less oxygen. I really don't want to give up wearing contacts?

Need to talk to eye: doctor. I would ask that to your opthalmologist. I feel that there is more a chance of you going blind wearing contacts. The oxygen is important and the new contacts are gas permeable. But....... I would not take the chance of infection or keratitis and go blind. Best wishes. ...Read more
