Ocular surface and corneal diseases, such as keratoconus, iritis and pterygium, all affect our eyes in different ways. Keratoconus<\/strong>\u00a0would affect the refractive power and accelerate the worsening condition of astigmatism. The corneal collagen cross-linking treats the condition by strengthening the cornea as the corneal collagen fibers cross-link. Iritis<\/strong>, a viral or bacterial infection of the anterior part of the uvea, could lead to complications such as examination before cataract surgery<\/a>, glaucoma and other complications. And\u00a0Pterygium is a benign conjunctival lesion, a triangular wing-shaped foreign body that covers the white of the eye and extends to the cornea. When the pterygium gradually grows toward the pupil, it may become inflamed and cause the white of the eye to become red and swollen.<\/strong>If the above situation occurs, you should contact our centre as soon as possible to arrange diagnosis and treatment.<\/p>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t Keratoconus , also known as cone cornea, occurs when the center of the cornea becomes thinner and is continuously pushed outward by the pressure within the eyeball, changing the original curvature of the cornea and causing it to bulge outward, forming a cone-shaped cornea. Keratoconus can affect the refractive power and accelerate the progression of astigmatism. The cause of Keratoconus is unknown, but it may be related to frequent eye rubbing, allergic diseases, and genetic inheritance. Patients usually develop the disease in adolescence or in their twenties. Since the early symptoms of corneal conus are not much different from ordinary astigmatism and myopia, patients may not find the problem and seek advice from an ophthalmologist, so it is difficult to diagnose. However, as the condition worsens, the vision may suddenly deteriorate. Even after treatment, corneal scarring may permanently affect vision.<\/p>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t Bulging outward of cornea<\/p>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t Worsening in a greater and faster manner in myopia or astigmatism<\/p>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t Decreased visual function<\/p>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t Hard contact lenses exert greater pressure on the top, so they can press the cornea to deform.

This corneal cross-linking surgery reduces the chance of corneal ectasia, deformation and degree rebound.<\/p>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\tKeratoconus<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
