Photo of author

Keratoconus is an ocular condition that is progressive in nature. It means that this disease progresses over time and worsens your eye health.

In Keratoconus, the cornea (the clear front layer of the eye) bulges outwards to form a cone-like shape due to thinning. It can cause problems like blurry vision and eye pain that may worsen over time.

Recognizing Keratoconus symptoms in the early stages can help receive timely treatment and prevent disease progression.

This article aims to enhance your understanding of Keratoconus symptoms so you can recognize them easily and take a step towards better eye health.

We will also discuss when to see a doctor and the treatment of symptoms of Keratoconus.

Symptoms of Keratoconus

It is difficult to identify Keratoconus in the early stages as it usually presents itself as vision problems like blurry or double vision.

These symptoms can be easily confused with another condition. However, taking the first step to learn Keratoconus symptoms can make all the difference you need to protect your eyesight.

Let us discuss the symptoms of Keratoconus in detail.

Blurry vision: The development of a cone-like shape of the cornea is associated with corneal thinning. The change in the shape of the cornea results in blurred vision.

Increased sensitivity to light: In the early stages, increased sensitivity to light is a common symptom of Keratoconus. 

It can be painful when the affected eye is exposed to light.

Distorted vision: The cornea is responsible for focusing light on the retina. The change in the shape of the cornea due to Keratoconus puts the light rays out of focus and causes distorted vision. 

Frequent changes in prescription: Glasses or contact lenses are often prescribed for vision correction. Frequent changes in the prescription of eyeglasses or contact lenses may indicate Keratoconus.

Keratoconus treatment focuses on slowing the disease’s progression and improving vision.

There are various surgical and non-surgical treatment options. 

Non-surgical treatment options include prescription glasses and contact lenses that can improve vision. 

Cross-linking therapy is also a non-surgical treatment that can slow or stop the progression of Keratoconus.
