What are Keratoconus?

Keratoconus is a degenerative eye condition in which the cornea thins and swells into a cone shape. It can worsen with time and usually appears in teens or early adulthood. Although the exact cause is unknown, environmental and genetic factors lead to keratoconus.

What are the Common Symptoms of Keratoconus?

Common signs of Keratoconus include

  • Distorted or hazy vision
  • Heightened sensitivity to light and glare
  • Frequent adjustments to the prescription for eyeglasses, and trouble seeing at night.
  • Severe visual impairment may result from corneal scarring in more advanced instances.

Causes and Risk Factors of Keratoconus

Although the real cause of keratoconus is unknown, a mix of biochemical, environmental, and genetic variables is thought to be responsible. Oxidative stress weakens the cornea, causing it to thin and swell gradually.

Risk Factors

  • Genetics: The risk is increased if there is a family history of keratoconus.
  • Regular Eye Rubbing: Excessive eye rubbing might accelerate the development of corneal damage.
  • Underlying Conditions: Asthma, Down syndrome, and Ehlers-Danlos syndrome are among the conditions associated with an increased risk.
  • Allergies or Chronic Eye Irritation: Prolonged inflammation of the eyes can weaken the cornea.
  • Hormonal Changes: There may be a hormonal component to the disease, as it frequently worsens during puberty and pregnancy.

Latest Research and Technologies in the Treatment of Keratoconus in Malaysia

With modern therapies like Corneal Collagen Cross-Linking (CXL) to stabilise and restructure the cornea and Corneal Allogenic Intrastromal Ring Segment (CAIRS) surgery, keratoconus therapy has advanced in Malaysia. Clinics provide individualised treatment through corneal transplants, Intacs, and contact lenses, depending on the severity of the disease. Future diagnosis and therapy approaches will be guided by the growing understanding of the condition's hereditary basis brought about by ongoing genetic research.

Keratoconus Prevention Tips

Although there is a genetic component to keratoconus, and it is not always curable, some lifestyle modifications can slow its progression:

  • Avoid rubbing your eyes as this damages the cornea and exacerbates keratoconus. If your eyes are irritated, use the prescribed antihistamine drops.
  • Control Allergies and Dry Eye: To avoid eye discomfort and rubbing, alleviate dry eye and allergic reactions.
  • Put on UV-protective sunglasses: Outdoor exposure to UV light can cause corneal thinning.
  • Maintain a Healthy Diet

Treatment options for Keratoconus

Cornea transplant: Advanced keratoconus can be surgically treated with a corneal transplant (keratoplasty). A cornea transplant is a surgical procedure that replaces a portion of the cornea with donated corneal tissue.


Cost Start From USD 5000 - USD 10000Explore Options

There are various Diagnostic tools for diagnosing Keratoconus treatment:

  • Corneal Pachymetry(determines corneal thinning by measuring corneal thickness).
  • Wavefront Aberrometry evaluates optical distortions brought on by abnormalities in the cornea.
  • Keratometry: Determines aberrant steepening by measuring corneal curvature.
  • Optical Coherence Tomography (OCT) offers high-resolution cross-sectional imaging for early identification and monitoring.

MediRehab (a chain of Rehab centres, part of MediGence) provides comprehensive rehabilitation services to support patients through Teleconsulations and online therapy sessions. Keratoconus rehabilitation emphasises

  • Lifestyle modifications, disease treatment, and vision correction to improve quality of life.
  • Lifestyle changes include avoiding eye rubs, controlling allergies, and preserving eye health through a healthy diet and adequate water.
  • Visual therapy examples are Low vision aids, anti-glare glasses, UV-protective lenses and assistive devices that can help control symptoms.
  • Depending on the situation, your healthcare professional may prescribe medicine to help control your symptoms and support the treatment plan.

Frequently Asked Questions

Keratoconus can be treated, although it cannot be cured completely. Treatment goals are stabilising the cornea, improving eyesight, and decreasing the progression. The likelihood of successful treatment rises with early diagnosis. Treatment possibilities include intracorneal ring segments (ICRS), corneal cross-linking (CXL), glasses, specialist contact lenses, and corneal transplants in more severe cases, depending on the severity.

Advanced techniques include Corneal Cross-Linking (CXL), Intracorneal Ring Segments (ICRS), and corneal transplants. These techniques significantly improve eyesight and slow the progression of the illness, making keratoconus therapy very successful in Malaysia.

Yes, many hospitals offer the following for Keratoconus treatment:

  • Malaysia provides excellent, reasonably priced keratoconus care with top-notch facilities and knowledgeable ophthalmologists.
  • Prominent eye centres employ personalised scleral lenses, topography-guided laser treatments, AI-based diagnostics, and sophisticated corneal cross-linking (CXL).
  • Intracorneal Ring Segments (ICRS), topography-guided laser treatments, and corneal transplants guarantee advanced diagnostic tools and treatments.

Always consider the following factors when selecting Malaysian hospitals:

  • Hospitals that are accredited (authorised by JCI).

More than 90% of patients in Malaysia who have Keratoconus treatment report improved vision and stability following operations such as corneal cross-linking, INTACS, or lasers. The treatment approach and the degree of the ailment determine the results.

Keratoconus results in uneven astigmatism because of corneal thinning and irregular shape, which causes blurry, distorted vision. Driving at night and performing daily tasks is challenging due to light sensitivity and glare. Prescriptions must be changed frequently, and surgery or specialist lenses may be necessary in extreme situations.

Most hospitals in Malaysia offer the following:

  • Assistance in obtaining visas.
  • Airport Service to and from the hospitals.
  • Multilingual experts and the Best accommodation services.
  • Personalised treatment plans for patients from abroad.

Despite being regarded as relatively rare in Malaysia, keratoconus is frequently identified due to increased awareness and improved screening tools.

Untreated keratoconus can result in corneal scarring, significant visual impairment, and, in rare instances, abrupt corneal swelling (hydrops), which can cause agony and abrupt blindness. Due to severe thinning and irregularities, advanced stages may necessitate corneal transplantation.

Malaysia is a cost-effective choice for those seeking treatment because it provides top-notch medical care at affordable costs compared to several Western nations.

Yes, Malaysia's healthcare system accepts patients from abroad and provides excellent Keratoconus treatments at many clinics and hospitals.

Yes, many Malaysian hospitals offer in-person and online consultations to foreign patients who want a second opinion.
