Ocular surface and corneal diseases, such as keratoconus, iritis and pterygium, all affect our eyes in different ways. Keratoconus<\/strong>- can affect the eye\u2019s refractive ability and accelerate the progression of astigmatism. Corneal collagen cross\u2011linking strengthens the cornea by binding the collagen fibers more tightly together, providing treatment for keratoconus.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>It is a benign conjunctival growth, appearing as a triangular, wing\u2011shaped tissue that spreads over the white of the eye and extends to the cornea. When the pterygium gradually grows toward the pupil, it may become inflamed, causing redness and swelling of the eye. If these symptoms occur, please contact our center promptly to arrange diagnosis and treatment.<\/p>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t Also known as keratoconus, this condition occurs when the central cornea becomes thin and is pushed outward by intraocular pressure, altering its normal curvature and causing the cornea to bulge into a cone\u2011like shape. Keratoconus can impair the eye\u2019s refractive ability and accelerate the progression of astigmatism. The exact cause is still unclear, but it may be related to frequent eye rubbing, allergic diseases, or genetic factors. Symptoms usually appear during puberty or in the twenties. Since early keratoconus resembles common astigmatism or myopia, patients may not realize they have a problem or seek medical advice, making diagnosis more difficult. As the condition progresses, vision may suddenly deteriorate, and even after treatment, corneal scarring can lead to permanent visual impairment.<\/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\t\t\t\t\t\t\t\t\t\t\t\t\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
