What Is the Best Treatment for Keratoconus?
Keratoconus is an eye condition where the cornea, the clear dome-shaped part of the eye, thins and begins to bulge into a cone-like shape. This irregular shape can cause blurry or distorted vision, and in more severe cases, it can lead to significant sight loss. But what is the best treatment for keratoconus? In this article, we will look at various treatment options, from early-stage remedies to advanced solutions, so you can understand which might be best suited for managing this condition.
Early Detection and Non-Surgical Treatments
For individuals diagnosed in the early stages of keratoconus, the first line of defence often involves using eyeglasses or soft contact lenses. These help to correct mild distortion in vision. In the beginning, keratoconus may not be highly advanced, so simple solutions like these can provide relief.
Eyeglasses and Soft Contact Lenses
Eyeglasses are typically prescribed to improve blurry vision in the initial stages. However, as the condition progresses and the cornea becomes more irregular, soft contact lenses might no longer offer adequate correction. For many people, this is the stage when they explore other options.
Rigid Gas Permeable (RGP) Contact Lenses
Rigid Gas Permeable contact lenses are a popular non-surgical option when keratoconus worsens. Unlike soft lenses, RGP lenses are firm and do not mould to the irregular shape of the cornea. Instead, they sit on top of it, providing a smooth surface that corrects the distortion in vision. Many patients find that RGP lenses offer sharper vision than soft lenses, especially when the corneal bulging becomes more pronounced.
Hybrid Contact Lenses
For those who find RGP lenses uncomfortable, hybrid lenses could be an option. These lenses have a hard centre like RGP lenses but a soft outer ring. This combination can give sharper vision while offering more comfort than traditional RGP lenses. Hybrid lenses may be particularly beneficial for people who need improved vision but struggle with the comfort of RGP lenses.
At What Age Does Keratoconus Start?
Advanced Treatments: Corneal Collagen Cross-Linking (CXL)
Corneal Collagen Cross-Linking (CXL) is one of the most significant advances in keratoconus treatment. It is a non-invasive procedure designed to strengthen the cornea and prevent further progression of the disease.
What Is Corneal Collagen Cross-Linking?
CXL works by using ultraviolet (UV) light and a special riboflavin (vitamin B2) eye drop to strengthen the collagen fibres within the cornea. The treatment typically takes about 30 minutes and is performed under local anaesthesia. The goal is to halt the progression of keratoconus, stopping the cornea from becoming more irregular and preventing further vision loss.
Who Can Benefit from CXL?
CXL is particularly useful for people with mild to moderate keratoconus. It is most effective when done in the early stages before the cornea has become too thin. Many patients who undergo CXL experience a halt in the progression of the disease, and some even see a slight improvement in their vision over time.
Can Keratoconus Be Cured with Medicine?
Scleral Contact Lenses
When the condition has advanced and other contact lenses no longer provide good vision, scleral lenses may be an option. These are larger lenses that sit on the sclera (the white part of the eye) rather than directly on the cornea. They create a fluid-filled vault over the cornea, offering both comfort and improved vision for people with severe keratoconus.
Intacs: Corneal Implants
Intacs are small, crescent-shaped plastic inserts that are surgically placed into the cornea. They help flatten the bulging cornea and improve vision. This is a minimally invasive procedure and is often used in patients who are not ready for corneal transplant surgery but are no longer finding success with contact lenses.
Who Can Benefit from Intacs?
Patients with moderate keratoconus who are experiencing significant vision loss may find Intacs helpful. While it does not cure keratoconus, it can improve the cornea’s shape and allow for better vision correction with glasses or contact lenses.
How Successful Is Keratoconus Surgery?
Corneal Transplant Surgery
In the most advanced cases of keratoconus, where the cornea has become severely damaged and vision is highly impaired, a corneal transplant may be necessary. This involves replacing the damaged cornea with a healthy donor cornea.
Types of Corneal Transplants
There are two main types of corneal transplants:
- Penetrating Keratoplasty (PK) – This is a full-thickness corneal transplant where the entire cornea is replaced.
- Deep Anterior Lamellar Keratoplasty (DALK) – In this type, only the outer and middle layers of the cornea are replaced, leaving the inner layer intact. This method is often preferred because it carries a lower risk of rejection.
When Is a Corneal Transplant Recommended?
Corneal transplant surgery is typically reserved for patients with severe keratoconus that cannot be managed with other treatments, such as contact lenses or Intacs. While it is considered a last resort, the success rate is generally high, and many patients regain significantly improved vision after the surgery.
What is the Cause of Keratoconus?
Which Treatment Is Best for You?
The best treatment for keratoconus largely depends on the severity of your condition. For early stages, eyeglasses and contact lenses, such as RGP or hybrid lenses, may be enough to correct vision. If your condition is progressing, Corneal Collagen Cross-Linking can help stop it in its tracks. For more advanced keratoconus, options like scleral lenses, Intacs, or even a corneal transplant may be necessary.
It’s essential to consult with an eye care specialist to determine the best course of action based on your individual needs. Early diagnosis and treatment are crucial to maintaining your vision and preventing further damage.
Conclusion
Keratoconus can be challenging, but many effective treatments are available. Whether you’re managing the early stages or dealing with more advanced symptoms, options like RGP lenses, CXL, or even corneal transplants offer hope. The key is to seek treatment early and work closely with your doctor to find the best solution for your eyes.
By staying informed and taking proactive steps, you can manage keratoconus and maintain your quality of life.

What Should You Avoid if You Have Keratoconus?
Frequently Asked Questions
What are the early symptoms of keratoconus?
Early symptoms include blurry vision, sensitivity to light, and frequent changes in eyeglass prescriptions. As the condition worsens, vision may become increasingly distorted and harder to correct with regular glasses or contact lenses.
3. How is keratoconus diagnosed?
Keratoconus is diagnosed through a comprehensive eye exam, including corneal topography, which maps the cornea’s surface. Additional tests may measure the cornea’s thickness to assess the severity of the condition.
4. Can keratoconus be cured?
While keratoconus cannot be fully cured, treatments like corneal cross-linking can halt its progression. Other solutions, such as contact lenses or corneal transplants, can help improve vision and manage the condition effectively.
5. What is corneal collagen cross-linking?
Corneal collagen cross-linking (CXL) is a non-invasive procedure that strengthens the cornea using UV light and riboflavin. This treatment can slow or stop the progression of keratoconus and, in some cases, improve vision.
Can keratoconus lead to blindness?
Keratoconus rarely causes complete blindness. However, without treatment, severe cases can lead to significant vision impairment. Early diagnosis and proper treatment can prevent the condition from worsening and preserve vision.
When is a corneal transplant needed for keratoconus?
A corneal transplant is considered when keratoconus becomes severe, and other treatments like contact lenses or cross-linking no longer provide sufficient vision correction. It is typically the last resort for advanced cases.
