Astigmatism VS Keratoconus

Published 2024-03-28
Though similar in some ways, they are two distinct corneal conditions:
#astigmatism is when the cornea becomes slightly misshapen or curved, resulting in blurred vision. It RARELY progresses at a rapid rate.
#keratoconus or KC, is when the cornea thins over time, forming a cone-like shape. This may cause extreme blurred vision, extreme levels of glare, and frequent prescription changes. Rapid disease progression is also possible.

Just had corneal crosslinking done in my left eye a week ago. Totally back to normal, no pain . A little blurry but that’s expected

Astigmatism: a type of refractive error caused by a misshapen cornea or lens (usually cornea). Usually refers to "regular astigmatism." Almost everyone has a little astigmatism but significant levels can cause glares and halos and blurred vision. Regular astigmatism: a very common type of astigmatism caused by a spherocylindrical shaped cornea. Can be treated with glasses. Usually not associated with a disease. Irregular astigmatism: an uncommon type of astigmatism which is not spherocylindrical. Usually associated with a disease. Usually can't be corrected with glasses as glasses only have spherical and cylindrical power. But rigid contact lenses interact with the tears on the surface of the cornea to correct irregular astigmatism in ways glasses cannot. Keratoconus: a rare, progressive corneal disease that causes an irregular astigmatism shaped like a cone (hence its name). Owing to its progressive nature it can worsen rapidly over time and may even require a corneal transplant in some instances.

I've got KC. The special contacts I have to wear are $$$$. Health insurance won't cover any of it. Plus I have to wear glasses on top of the contacts .
-
i have both I believe it’s very difficult difficult to find a doctor that can fit you with specialized contact lenses
-
Thanks
-
Thank you 😊
-
Could you please do a review of the CorneaCare self heating warm compress? I want to purchase them but l'd like to see how these compare to other warm compresses.
-
That's interesting
-
I'm 24 years I can't see with out glass my left eye 7 right 8
-
Ok hear me out I was wondering you could make a video on this. I am not nearsighted nor far sighted though I am both near and far sighted (near in on eye far in the other) what’s funny is I used to believe I had perfect vision but I was clearly long
-
Cute n smart ❤
-
I found out I had KC and just gave up and let my eye do what it’s gonna do… I barely use it any more - preferring to close that eye and use my working one instead
-
Can you speak about Hyperopia??
-
I'd like to thank Optical Coherence Tomography machines.

I don't think your filter for astigmatism is really the right one. It doesn't represent light haloing/rays. That's really what astigmatism does and there are good filters out there to show it. It's characteristically different from just generally blurry vision
-
My eye doctor won't take me seriously or do more extensive testing because I can pass the letter chart easily. What can I do?
-
A video on fuchs coming up I'm in the future doc?
-
It ot normal my prescription went from -4,25 to -6,00 within a year? Had 2 periods with rapid vision loss (days). But when I checked after the first period, they said my strength was still the same, even though i could clearly see sharper woth -5,00 instead of -4,25
-
I’ve had PKP in both eyes due to KC. Fun times…

Do you know anything about Choroidereamia ?
