KERATOCONUS

Introduction to Keratoconus

If you’ve been diagnosed with keratoconus, you might have questions about how it will affect your vision and your future. Keratoconus is a progressive eye condition that impacts the cornea, the clear, dome-shaped front part of your eye. As the cornea thins and bulges outward into a cone-like shape, it can distort your vision. The good news is that there are many ways to manage keratoconus and improve your quality of life.

What is Keratoconus?

Keratoconus changes the shape and structure of your cornea, affecting how light enters your eye. This can lead to blurry or distorted vision and other symptoms such as increased sensitivity to light. Let’s explore the causes of this condition and how it can be treated.

 

Causes and Risk Factors

The exact cause of keratoconus isn’t fully understood, but certain factors may increase your risk:

GENETICS:

  • Keratoconus often runs in families, suggesting a genetic link.

Eye Rubbing:

  • Chronic eye rubbing is a significant risk factor and may accelerate the progression of keratoconus.

Other Factors:

  • Environmental factors such as exposure to UV light and certain systemic conditions like asthma or eczema may also play a role.

Symptoms and Progression

Common symptoms of keratoconus include:

Blurred Vision:

  • Vision may become blurry or distorted as the cornea changes shape.

Sensitivity to Light:

  • You might notice an increased sensitivity to bright lights.

Ghosting or Double Vision:

  • Multiple images may appear due to corneal irregularities.

Eye Irritation:

  • You may experience mild irritation or discomfort in your eyes.

Keratoconus typically starts in the teenage years or early adulthood and progresses at different rates for each person.

Diagnosis of Keratoconus

To diagnose keratoconus, your eye care professional will perform a comprehensive eye examination that includes:

Visual Acuity Testing:

  • Measures how clearly you can see.

Retinoscopy:

  • Uses a retinoscope to measure how light is reflected by your retina and assess refractive error

Slit-Lamp Examination:

  • Examines your cornea and other eye structures for signs of keratoconus and other abnormalities.

Corneal Topography:

  • Maps your cornea’s curvature and thickness, providing detailed information about its shape and irregularities. This imaging technique uses a specialized camera to create a color-coded map of the cornea’s surface, which is essential for diagnosing keratoconus and monitoring its progression.

Pachymetry:

  • Measures the thickness of your cornea to check for thinning.

Treatment Options for Keratoconus

There are several ways to manage keratoconus and improve your vision:

Non-Surgical Treatments

Prescription Glasses:

  • Glasses can help correct mild vision problems in the early stages of keratoconus.

Contact Lenses:

  • Specialty contact lenses, such as rigid gas permeable (RGP) and scleral lenses, can offer better vision correction.

Rigid Gas Permeable (RGP) Lenses:

    • These lenses create a smooth surface for light to focus correctly, improving your vision.

Scleral Contact Lenses:

    • Scleral lenses are larger lenses that rest on the white part of your eye (sclera). They vault over the cornea, smoothing out the irregular surface and providing excellent vision correction. These lenses are comfortable and custom-made for your eye shape.

Surgical Treatments

In more advanced cases, surgical interventions may be required. Here are some of the options available:

Corneal Cross-Linking (CXL):

  • Corneal cross-linking is a minimally invasive procedure that uses riboflavin eye drops and UV light to strengthen your cornea. By creating new cross-links between collagen fibers in the cornea, the procedure can slow or stop the progression of keratoconus and improve corneal stability.

Corneal Cross-Linking Combined with Phototherapeutic Keratectomy (PTK):

  • This combination treatment can be particularly effective for keratoconus patients. PTK uses an excimer laser to smooth the cornea’s surface by removing a thin layer of tissue. When combined with corneal cross-linking, PTK can improve visual acuity and correct refractive errors while also stabilizing the cornea. This approach can provide better overall outcomes for patients with keratoconus.

Intracorneal Ring Segments (ICRS):

  • Small, crescent-shaped devices inserted into your cornea to reshape it and improve your vision.

Topography-Guided Surface Ablation (TREK):

  • TREK is a laser procedure that uses topographical mapping to guide the laser treatment. It reshapes the cornea according to its specific irregularities, improving visual acuity and corneal symmetry.

Photorefractive Keratectomy (PRK):

  • PRK is a laser eye surgery that reshapes the cornea’s surface, benefiting keratoconus patients by smoothing out corneal irregularities.

Deep Anterior Lamellar Keratoplasty (DALK):

  • DALK is a partial-thickness corneal transplant that replaces the damaged outer layers of the cornea while preserving the inner layer (endothelium). This reduces the risk of rejection and other complications.

Living with Keratoconus

Living with keratoconus can be challenging, but there are ways to manage the condition:

Regular Eye Examinations:

 Regular check-ups help monitor your condition and adjust treatments as needed.

Eye Protection:

  • Avoiding eye rubbing and using protective eyewear can prevent further damage to your cornea

Support Groups:

  • Joining a support group can provide emotional support and practical advice. Check out resources like Keratoconus Group for more information and support.

Personal Stories and Testimonials

Hearing from others who have keratoconus can be inspiring and encouraging. Their stories can offer insights into living with the condition and the impact of different treatments.

Frequently Asked Questions (FAQs) on Keratoconus

Here are some common questions about keratoconus and their answers:

The exact cause isn’t fully known, but genetics and environmental factors play a role.

    • Symptoms include blurred or distorted vision, light sensitivity, and ghosting or double vision.
    • Options include glasses, specialty contact lenses (especially scleral lenses), and corneal cross-linking. Surgical options include intracorneal ring segments, TREK, PRK, and DALK.
    • Diagnosis involves an eye examination, including visual acuity testing, retinoscopy, slit-lamp examination, corneal topography, and pachymetry.
    • Corneal cross-linking (CXL) is a minimally invasive procedure that strengthens your cornea using riboflavin eye drops and UV light. It can slow or stop keratoconus progression.
    • Corneal cross-linking combined with phototherapeutic keratectomy (PTK) is a treatment option that combines the cornea-stabilizing effects of cross-linking with the surface smoothing benefits of PTK. This combination can improve visual acuity and correct refractive errors while stabilizing the cornea.
    • There is no cure, but treatments like corneal cross-linking can slow or stop its progression, and other treatments can improve vision.
