The cornea provides most of the eye’s focusing power—about four-fifths of incoming light is bent here. Unlike most tissues, it is transparent and contains no blood vessels, serving as the eye’s “window.” It is also richly supplied with pain-sensitive nerves. Because of that, corneal issues typically cause eye pain, light sensitivity, and changes in tearing—either too little or too much.
A tooth implant in the cornea can help restore vision in cases where severe forms of corneal damage have resulted from a chemical burn, a fire or explosion, or an autoimmune reaction where the immune system attacks the eye. Continue reading “Amazing Cornea Facts: Tooth Implant Restores Sight”
The cornea is in front of the lens. It is a clear layer, seeming to lack substance. However, it is comprised of multiple layers and groups of cells and proteins which are highly organized.
Current research on genetic eye diseases focuses mostly on genetic therapies. Scientists have learned how to sequence DNA at a relatively low cost. New tools for modifying genetic materials, such as the CRISPR, have opened the door for new treatments and even cures. Certain eye disorders are caused by mutated genes and genetic predispositions. This article highlights current research into four genetic eye disorders 
Have you ever heard that your eyes need plenty of nutrition? It’s true, and research backs this up. But did you know that the Standard American Diet tends to be very low in some eye-essential nutrients? The eyes are the second most physiologically active part of our body (#1 is the brain). At Natural Eye Care, we believe the eyes require approximately 25% of the nutrients we take into our body, if we eat a healthy diet. Even though most Americans consume enough calories, we may still have poor nutrition for the eyes. No wonder Macular Degeneration, cataracts, glaucoma, optic nerve 
Cornea transplant surgery involves removing a damaged or diseased cornea, and replacing it with tissue from a deceased donor. All or part of the cornea may be replaced. In the United States, eye surgeons do approximately 33,000 corneal transplants (keratoplasty) per year. The surgery might be recommended if vision is seriously impaired by scarring from an injury, or eye diseases such as Fuchs’ Dystrophy, Lattice Dystrophy, or Keratoconus.
Fuchs’ Corneal Dystrophy is named for the Austrian ophthalmologist Ernst Fuchs, who first described the condition in 1910. He described thirteen patients who suffered from corneal clouding, blisters on the corneal epithelia and loss of corneal sensation.
