regenerate thinning cornea with collagen supplements

Is it possible to regenerate thinning cornea with collagen supplements, vitamins or other natural way?

Yes, it is can be possible…

Collagen supplements, vitamins or other natural ingredients, and whole foods can play a role in regeneration of cornea, but regular optometrist visits and proper maintenance are important in preserving your vision and corneal health.

In some cases thinning cornea are due to nutritional deficiencies, in these cases support by collagen, vitamins and other supplements may be helpful.

The cornea, which is a complex group of proteins and cells, is a transparent structure that is responsible for the refraction of light, and it is the initial point of visual contact. The cornea is rich in glutathione and deficiency of glutathione may be the reason corneal thinning. So, it is beneficial to prevent and support the regeneration of the cornea. Glutathione is a tripeptide produced naturally by the body. For its production, however, you must consume adequate amounts of cysteine, glycine and glutamic acid. Glutamic acid and glycine are rarely in short supply, whereas cysteine must be made by the essential amino acid methionine. Foods high in this compound are generally high in sulfur and include egg yolks, red peppers, garlic, onions and cabbage.


Vitamin C

Vitamin C is one of the most powerful antioxidants and one of the most important in the lens of the eye, second only to glutathione. This compound helps in the production of collagen, which helps to strengthen capillaries, including those that provide nourishment to the retina, and prevents cataracts by guarding the lens against free radical damage. It is also beneficial for thinning cornea.

Vitamin E

Like vitamin C, vitamin E’s benefits for the cornea center around its antioxidant properties. Vitamin E helps to delay the onset of macular degeneration related to aging and from cataracts. Low vitamin E levels in the body weaken capillary walls and can cause tiny white or yellow deposits to form on the retina — a sign of degeneration. Foods rich in vitamin E include asparagus, avocado, dried prunes, soy and wheat germ oil.

Collagen

The eye is formed by many types of collagen, but collagen XVIII is particularly important because it makes up your cornea. Many types of scientifically approved products are available to regenerate cornea. Iontophoretic corneal collagen crosslinking (I-CXL) with riboflavin and ultraviolet has been proved to be effective in eyes with very thin corneas with no side effects. This form of collagen could be used in patients with keratoconus and more advanced keratoconus. Keratoconus is the most common corneal dystrophy, with a frequency of about 1 to 2000, manifested by progressive thinning and deformation of the cornea, resulting in myopia and irregular astigmatism.

Collagen vitrigel, a transparent, thin and biocompatible membrane, could be a promising material for supporting the regeneration of corneal epithelium and stroma. Collagen vitrigel is composed of high-density type I collagen fibrils. So, ultimately collagen can help in regeneration of cornea. A bioengineered and recombinant form of collagen is also available to regenerate cornea.
