1 in 2,000 people gets diagnosed with Keratoconus and you probably don’t even know about it. Keratoconus is an eye condition that results when the cornea bulges outward into a cone shape rather than taking spherical shape. The dome-shape cornea is held together by collagen and when these protein fibers weaken, cornea takes the shape of cone slowly. Following are 5 things that you should know about Keratoconus: Keratoconus makes the clear vision impossible without the assistance of eyeglasses or contact lens. It surely damages the vision while some cases even require corneal transplant to improve vision. It begins when you are a teenager but can occur at the age of 30. If any one family member has Keratoconus then it’s better to have proper eye-check from the early age of 10. It can reach to more severe stage in individuals with certain allergies. LASIK should not be done with Keratoconus as it can weaken the cornea even more and make your vision worse. Even if keratoconus has minimal effect on vision but it can be dangerous with LASIK. Keratoconus is not a blinding condition but requires proper hands-on management and with proper management it is completely manageable. Corneal collagen cross linking is the only treatment which can halt the condition from getting worse. It can also be alleviated through the use of contact lens or glasses. Intacs is a type of implant which can be inserted beneath the cornea to provide more structural stability.
