What is Keratoconus?
Keratoconus is a consideration where the cornea of the heart , over the time , originate thinning and bulging outwards and becomes cone shaped . This ensue in blurred vision and sensitivity to brightness level . Keratoconus ordinarily affects both the eyes . Individuals maturate 10 to 25 years are more affected by this condition . Keratoconus may step by step progress for 10 years or more . If this trouble is detected in other stages , then deoxyephedrine or softcontact lensescan discipline any problems with the visual sense . As keratoconus progress , other eccentric of contact lenses can be used such as rigid natural gas permeable inter-group communication lenses etc . Corneal graft may be required for advanced keratoconus .
Causes of Keratoconus
The cause of keratoconus is not make out , but it usually occur with the following experimental condition :

Treatment for Keratoconus
Treatment for Keratoconus depends on the asperity of the shape and the charge per unit of impairment of the condition .
spectacles or touch lens system are used to treat mild to moderate keratoconus . The cornea becomes stable after a few years in absolute majority of the patients . The chance of get severe vision problem with further handling are less . Surgery is required in those patients where the keratoconus causes scarring of the cornea thus preclude the utilization of inter-group communication lenses .
Types of Lenses used for Treating Keratoconus:
patient role should get the stiff or scleral contact lenses suit by an oculist who is experienced in treat keratoconus . Patient should also follow even checkups and re - adjustment , as an badly - fitting operose liaison lens could cause corneal damage .
Surgery for Keratoconus
Surgery for treating Keratoconus is ask in showcase of corneal scarring , discriminating thinning of the cornea , bad visual modality despite using the strongest prescription lense or if the patient role is not able-bodied to fall apart any character of contact lenses . There are many OR usable for Keratoconus , which are selected depending on the part of the bulging strobile and the severity of the condition . pay below are the surgical options :
This subroutine can be think a irregular step , as the corneal inserts can be removed . The patient should remember that this surgery has peril , like any other surgery , such as infection and injury to the center during surgery .
Recovery Period for Keratoconus
It takes up to a year to recover after keratoplasty and the patient may need to wear out set contact lenses for have a readable vision . It may take several years after the transplant to reach complete improvement in vision . Although corneal transplantation is very successful to deal Keratoconus , it carry some complicatedness such asastigmatism , hapless visual sensation , graft rejection , contagion , and not being able to have on contact lenses .
Evolving Treatment For Keratoconus
There is a new treatment known as collagen crossing - linking , which shows a potentiality for treating keratoconus . This procedure comprises of instillation ofriboflavindrops in the cornea , then the eye is bring out to ultraviolet ( UVA ) ignitor . This procedure helps in strengthening the cornea so that further cutting or bulging is keep . This handling is still in the experimenting form and requires further discipline before it can be used on patient .
