Keratoconus is a condition that damages the cornea that is present in the front portion of your eye. It weakens your cornea, leading to slow damage to your vision. It usually appears at age 10 and gradually increases as you age. You may also find it in people above 40; however, it is uncommon among that age group. It causes damage to both eyes, where the infection on one is higher than on the other. There is yet to be a proven method to identify the pace at which it grows.


The health of your cornea is crucial as it can only help you see the world. If diagnosed with Keratoconus, it changes the shape of the cornea, and the individual may even lose their ability to see when it is undiagnosed.

Find everything you need to know about Keratoconus, its causes, symptoms, and the treatments available to help the affected individuals below.


What Is Keratoconus?

Keratoconus is an eye problem where the front of your cornea becomes slim and inflates on the outside like a cone shape. This may impact your ability to see clearly, and you may experience high sensitivity to light. The infection in one eye is always more than the one in the other eye. This is found in people between 10 and 35 and worsens slowly, leading up to ten or more years.

Unfortunately, developing Keratoconus cannot be prevented, but you could correct vision using spectacles and lenses in the early stages. In due time, you need rigid gas permeable contact lenses or scleral lenses to support your vision. If your case worsens, you may have to take up corneal transplantation.

What Causes Keratoconus?

There is no definitive cause for Keratoconus, but researchers believe an individual acquires it during birth. It may also be caused due to the imbalance of corneal collagen on the corneal surface. There are other risk factors that cause Keratoconus, including


If Keratoconus runs in your family, the chances that you will get it are highly likely. You should be aware of the condition and get you and your family tested to get proper treatments from the early stage.


Researchers identified a link between Keratoconus and certain disorders like Down syndrome, Ehlers-Danlos syndrome, osteogenesis imperfecta, and retinitis pigmentosa. People with these disorders have a high chance of getting Keratoconus.

Age Factor

Keratoconus is prevalent among teenagers. It is also found in people above 40, but it is not that common and is usually a development from the diagnosis in their teenage years. There is also a chance for teenagers to be found with advanced Keratoconus.

Eye Inflammation And Rubbing

If you have allergies or any infection that may cause eye inflammation, it may damage the corneal tissues and develop Keratoconus. Frequent eye rubbing can also corrupt your cornea. If you already have Keratoconus, it increases the speed of progression.


What Are The Symptoms Of Keratoconus?

The affected people may not know the symptoms of Keratoconus. It first causes a minor change in the vision, which may progress into serious conditions. You may also find the following symptoms from eye exams.

  • Increased sensitivity to light
  • Difficulties with seeing clearly during the night
  • Irritation and head pain, along with eye pain
  • Seeing halos around lights
  • Unclear vision
  • Double vision

How Keratoconus Affects Vision?

There are chances for Keratoconus to change your vision and make it challenging to see without spectacles or soft contact lenses. It does not cause any significant impacts on your vision in the early stages. However, if left untreated, you may witness changes in cornea shapes, slimming of the corneal layer, and loss of transparency of the cornea in the later stages.

How Is Keratoconus Diagnosed?

Doctors can diagnose Keratoconus based on your family history with the disease and through specific eye exams. They can also perform a few tests to diagnose the disease, which are given below.

Corneal Topography

This test helps with the early diagnosis of Keratoconus. The doctor takes a digitized image to track and monitor the surface of the cornea. It also develops a map of the cornea’s curve, which helps accurately assess Keratoconus.

Slit-Lamp Exam

The slit-lamp exam helps the eye doctor check for deformities in the layers of the cornea. The doctor confirms if you have Keratoconus based on the damages observed in the cornea.


The ophthalmologists perform this test to identify the thickness of the cornea. They find the lean area of the cornea to diagnose your eyes for Keratoconus. It is one of the simplest and easiest tests for keratoconus screening.

How Is Keratoconus Treated?

Treatments for Keratoconus vary based on the stage of diagnosis and severity of the infection. Find some of the treatments that can help treat Keratoconus.

Glasses And Contact Lenses

People with less developed Keratoconus can use glasses to improve their eyesight. In some cases, if your infection grows rapidly, glasses cannot help you with your vision, and contact lenses may be required to improve vision of the affected eye.

Corneal Collagen Cross-linking

The corneal collagen cross-linking treatment is for people in the intermediate stage of infection. The doctor applies vitamin B solution to your eye and activates it using ultraviolet rays for almost thirty minutes. This helps stimulate and create new collagen bonds to bring back the strength and shape of your cornea.

Corneal Ring

A corneal ring helps people with advanced Keratoconus. The patient may not feel comfortable using contact lenses. In such cases, the doctor suggests the implantation of two C-shaped rings, which can help flatten the cornea’s front surface. This treatment can improve eyesight and enables patients to wear contact lenses.


Keratoplasty is nothing but a corneal transplant. It is a golden treatment for severe Keratoconus. Here the doctor performs surgery, removes all the affected parts of the cornea, and replaces it with a healthy cornea acquired from a donor. The doctor can complete the transplant using two ways, deep anterior lamellar keratoplasty dalk, where they remove and replace the outer surface of the cornea. The second is penetrating keratoplasty, performed to replace the whole cornea.

What Are The Risk Factors For Keratoconus?

Keratoconus formation may be influenced by a variety of causes. Among them, parental connection, history of Keratoconus in the family, and vigorous eye rubbing positions themselves as serious factors to be considered for keratoconus development. The other less essential elements are contact lens usage, eye trauma, obesity, exposure to sunlight, and smoking.

When To Visit A Doctor?

Keratoconus is an uncommon disease, and there are only fewer chances of you getting affected by the disease. It is safe to take eye exams regularly to get your eyes checked for any eye-related problem, including Keratoconus. If you experience constant irritation in your eyes or feel like you are losing your ability to see clearly, seek professional help immediately. Your doctor can evaluate your condition through various diagnoses and provide the necessary treatment to treat Keratoconus.
