VitaminC before CXL
Permalink   
 


Could you comment such recommendation, which can be found in many clinics performing cross-linking:

"do not take Vitamin C supplements within 1 week of the CCL procedure".

Has anybody heard this guidance before the procedure?

 

I'm little confused, because Vit C is considered as essential for health in general.

Vit C has an effect on the healing process...actually it helpful for laser surgery recovery, but there are no results on its use with CXL, so its advised not to take it, because its use is unknown in CXL and so any effects good or bad can be taken out of the equation, if its not used (although some clinics do think its helpful, but there are no significant studied data on it)

Many thanks for the answer.
While writing this post I've found 2 contradictory statements:
"Vitamin C presents structural analogies with riboflavin and its capability to absorb UVA"
(source: bmctoday.net/crstodayeurope/2008/10/article.asp),

"Vitamin C reduce the amount of reactive oxygen for CXL"
(source: www.slideshare.net/mmrochen/corneal-cross-linking-with-new-beam-profile).

In that case what has to do a person who eat healthy (food containing much more well absorbing vitamins than supplements). How about other vitamins (E, D, etc.) which may play role in the process?

This could very well be right, either causing a positive or negative effect, until more comparative study is done will we know on its magnitude. until then, we know CXL is beneficial in treating progression for the vast majority with progressive KC.

It is unethical not to treat progression and to study it with a group who is still being experimented on with various unproven protocols with out animal studies done first to prove a hypothesis.

 Vitamin C is a powerful anti-oxidant and it can be used to maintain the collagen found in the cornea of the eye. Actually, the intake of vitamin C is really good for eye health and it will reduce the risk of several eye disorders like cataracts and macular degeneration. My ophthalmologist in Washington had advised me to include vitamin C and vitamin A rich food after my cataract surgery for a fast healing. But the thing is different in CXL, After this procedure, it will take almost 7 days to regenerate the skin layer, so there may chances for the occurrence of allergy or other infection immediately after the surgery. The intake of Vitamin C may cause skin tingling or irritation to some people so it is advised not to take it.
