Had an eye appointment today to see if my prescription needed updating. My distance vision is the same (weak), but there is no more astigmatism in my left eye! There was at this time last year. The only change has been Keto. So yay Keto!!!
No more astigmatism!

I have read testimonies from other people of eyesight improving, but I don’t know why. All I can guess is that since Keto is anti-inflammatory, your body can heal, as well as saturated fat being the building blocks for new cells. What else, I know not. I’m just excited.

Most likely reduced eye pressure leading to less distortion. Blood pressure reduction and/or reduced inflammation.

Wow, that’s super crazy! I have a wicked astigmatism that always makes doctors go “wait… what?!”
Hopefully keto can keep my eyes from getting worse as my eyesight has deteriorated quite a bit in the past few years.

don’t know if this applies to anyone ,but my dr said that high glucose in the blood causes vision problems. as you decreas the sugar,the vision will improve (clear i guess) and hopefully the more advanced eye issues (i always thought the age related ones glaucoma, catahracts (sp?) macular degeneration etc) should improve,unless the damage is too advanced,

As an optometrist, I can tell you that we don’t often see astigmatism reverse. One exception is in patients with tightening blood glucose control, as we know happens with keto. Astigmatism is caused by a distortion of one of the ocular media, usually the cornea, but occasionally the lens, or the retina. The fluctuation of astigmatism in some diabetics can be pinned to a change in shape of their lens as their blood glucose increases, and a reversal of the same with tighter blood glucose control. In diabetic patients with fluctuating prescriptions, I will often advise them to hold off on ordering specs until they have stabilised their blood glucose, knowing that there is a chance of reversal.

Hi Craig, another optometrist here.
I can add that keto might be helpful for glaucoma my eye pressure dropped a few points with keto (n=1). Also, without all the inflammatory sugars sucking up vitamins, the leafy greens will be even better value for macular problems. I had trace symptoms of epiretinal membrane which cleared on keto, staying off carbs and trans-fats (margarine and bakery carbs) is great for the eyes. Because astigmatism is structural rather than metabolic, the keto effects would be small. But I’m with Genevieve … celebrate every non scale win

Hi Peter. Welcome mate.
Nice n=1 experiment. What do you suppose is the mechanism for the pressure drop? Reduced inflow? Increased outflow? Uveo-scleral vs trabecular meshwork?
Assume you used the same tonometer pre and post intervention. Could the cornea have been significantly impacted enough to affect IOP measurement?
Certainly agree with your comment re increased efficacy of nutritional supplementation for AMD.
Very interested in your experience with improved symptoms relating to epiretinal membrane. Did you have reduction of symptoms only, or did you see membrane regression on OCT?
Agree that opportunity to impact astigmatism via a dietary intervention would be limited due to it’s structural nature, however take the case of a poorly controlled diabetic. Is a chance that irregular lenticular astigmatism induced by a swollen lens, could be reversed by better glycaemic control?
I’m on a journey, learning how this way of eating may bring benefits to myself and my patients. And yes, I’ll take any non-scale wins as well!
Finally, if you’re in Oz, you should get on board for Low Carb Thredbo 2017 in August. Would be good to catch up.
