Keratoconus is a corneal disease that occurs when the normally round dome-shaped cornea (the clear outer area of the eye) progressively thins causing a cone-like bulge to develop. Typically diagnosed during adolescence and early adulthood with a variable rate of progression.The bulging or “cone-shaped” protrusion is caused by the normal pressure of the eye pushing out on the thinned areas of the cornea. Since the cornea is responsible for refracting most of the light coming into your eye, an abnormal-shaped cornea can create reduced visual acuity and affect the way you see. This reduced visual acuity can make even simple daily tasks, such as driving, watching television or reading, difficult to perform. Causes And Risk The cause is Unknown. Keratoconus is more common in contact lens wearers and people with nearsighted eyes. Some researchers believe that allergy may play a role. Symptoms The earliest symptom is subtle blurring of vision that is not correctable with glasses. ( Vision is generally correctable to 20/20 with gas permeable contact lenses )
What are Intracoreal Rings ?
ICRS are tiny plastic ring segments that are implanted in the cornea even though they are very small, their mass is enough to change the shape of the front surface of the eye and correct refractive error. Imagining your cornea as a tent with curved top. If you push out the sides of the tent, the top flattens, similarly, when intacs inserts are placed in the side of the cornea, they flatten it just enough to correct Myopia and Keratoconus diseases How Long Does The Surgery Take? It takes approximately 15 – 30 minutes to place intacs in your eye. The total procedure for one eye , including preparation time, is usually less than an hour
What is Cross Linking?
Corneal Collagen Cross linking with Riboflavin, also known as CXL, CCR and CCL. A one-time application of riboflavin solution is administrated to the eye and is activated by illumination with UV-A light for approximately 30 minutes. - The aim of the treatment is to stabilize the cornea and prevent the progression of keratoconus and based on a significant stiffening of the corneal stroma due to photochemical cross linking of the single collagen fibers from “ denser network “ which leads to an increase in the overall stability of the cornea.
