Keratoconus is an ocular disease that usually occurs at the beginning of puberty and tends to progress until the third decade of life. As a result of this disease, the normal shape of the cornea, which is round spherical, changes into a cone and and cause a significant decrease in vision. Keratoconus is a progressive disease occurs in one or both eyes, but usually both eyes are affected.
What Is Keratoconus?
Keratoconus is a disorder of the eye which results in progressive thinning of the cornea and ultimately causes the cornea to weaken and bulge outward. This corneal abnormality is often in the lower half of the cornea and initially leads to astigmatism (it should be noted, however, that all cases of astigmatism are not due to keratoconus). In mild cases or in the early stages of keratoconus, eyeglasses can be used to correct astigmatism. So far, there has not been a certain treatment for slowing down the progression of keratoconus in the world. All treatments such as eyeglasses, contact lenses, intrastromal corneal ring segment have helped to correct only a part of the patient's vision.
