Keratoconus Care in Phoenix

What is Keratoconus?

Keratoconus is a progressive eye condition in which the normally round, dome-shaped cornea (the clear front surface of the eye) thins and gradually bulges outward into a cone shape. This irregular shape prevents light from focusing correctly on the retina, causing distorted and blurred vision.

At Arizona's Vision Eye Care Center, Dr. Page specializes in the diagnosis, management, and treatment of keratoconus. With advanced diagnostic technology and expertise in specialty contact lens fitting, we help patients with keratoconus achieve the best possible vision and maintain their quality of life.

Understanding Keratoconus

Keratoconus typically begins during the teenage years or early twenties and can progress for 10-20 years before stabilizing. The condition affects approximately 1 in 2,000 people, though recent studies suggest it may be more common than previously thought.

Causes and Risk Factors

While the exact cause of keratoconus isn't fully understood, several factors may contribute to its development:

• Genetics: Keratoconus can run in families, suggesting a genetic component
• Eye rubbing: Chronic, vigorous eye rubbing may damage corneal tissue
• Allergies: Severe allergies that cause frequent eye rubbing may increase risk
• Connective tissue disorders: Conditions like Ehlers-Danlos syndrome and Marfan syndrome
• Other conditions: Down syndrome, retinitis pigmentosa, and certain systemic diseases

Signs and Symptoms of Keratoconus

Keratoconus symptoms vary depending on the stage and progression of the condition. Common signs include:

• Blurred or distorted vision
• Increased sensitivity to light and glare
• Frequent prescription changes for glasses or contact lenses
• Inability to wear contact lenses comfortably
• Seeing multiple "ghost" images or halos around lights
• Clouding of vision
• Sudden worsening or clouding of vision (acute hydrops)
• Eye strain and headaches

Early symptoms may be subtle and similar to other vision problems, which is why comprehensive eye examinations are crucial for accurate diagnosis.

Advanced Diagnostic Technology

Accurate diagnosis is essential for effective keratoconus management. We use state-of-the-art diagnostic equipment to detect and monitor the condition:

Corneal Topography

This computerized imaging system creates a detailed three-dimensional map of your cornea's surface, revealing even subtle irregularities that indicate keratoconus. The color-coded maps show the curvature at thousands of points across the corneal surface.

Optical Coherence Tomography (OCT)

OCT imaging provides cross-sectional views of the cornea, allowing us to measure corneal thickness precisely and detect thinning patterns characteristic of keratoconus.

Corneal Pachymetry

This test measures corneal thickness, which is typically reduced in keratoconus patients. Monitoring thickness changes helps us track disease progression.

Refraction and Visual Acuity Testing

We perform comprehensive vision testing to assess how keratoconus is affecting your functional vision and to determine appropriate correction options.

Our Comprehensive Treatment Approach

Treatment for keratoconus is tailored to the severity of your condition and your specific visual needs. Our goal is to maximize your vision, slow disease progression, and help you maintain your lifestyle.

Early Stage: Glasses and Soft Contact Lenses

In the earliest stages, regular eyeglasses or soft contact lenses may provide adequate vision correction. We monitor your condition closely and recommend more specialized options as needed.

Specialty Contact Lenses

As keratoconus progresses, specialty contact lenses become the primary treatment for achieving clear, functional vision:

Rigid Gas Permeable (RGP) Lenses

These specialized hard lenses vault over the irregularly shaped cornea, creating a smooth optical surface that dramatically improves vision. RGP lenses are often the first choice for moderate keratoconus.

Scleral Lenses

These large-diameter lenses rest on the white part of the eye (sclera) and vault over the entire cornea. They're extremely comfortable, stable, and effective for advanced keratoconus. The space between the lens and cornea is filled with saline solution, providing additional comfort and protection.

Hybrid Lenses

Combining a rigid center with a soft outer skirt, hybrid lenses offer the crisp vision of RGP lenses with improved comfort. They're an excellent option for patients who struggle with RGP lens comfort.

Piggyback Lenses

This system involves wearing a soft lens with an RGP lens on top, combining comfort with excellent vision correction for challenging cases.

Advanced Keratoconus Treatments

For progressive keratoconus, we can coordinate referrals for advanced treatments:

Corneal Cross-Linking (CXL)

This FDA-approved treatment strengthens corneal tissue to slow or halt keratoconus progression. We co-manage patients undergoing cross-linking, providing pre and post-operative care and monitoring.

Intacs (Corneal Inserts)

These tiny arc-shaped inserts are placed in the cornea to help flatten the cone and improve vision. We refer appropriate candidates and provide ongoing care.

Corneal Transplant

In severe cases where other treatments aren't effective, corneal transplant surgery may be necessary. We work closely with corneal surgeons to ensure comprehensive care.

Expert Specialty Lens Fitting

Dr. Page has extensive experience fitting specialty contact lenses for keratoconus patients. Our fitting process is meticulous and patient-centered:

• Detailed measurements: We take precise corneal measurements to design lenses that fit your unique eye shape
• Trial lenses: You'll try diagnostic lenses to ensure optimal fit and vision
• Fine-tuning: We make adjustments until you achieve the best possible comfort and vision
• Training: We provide thorough instruction on lens insertion, removal, and care
• Ongoing support: Regular follow-ups ensure your lenses continue to work well as your condition evolves

Living with Keratoconus

With proper treatment and management, most people with keratoconus can maintain excellent functional vision. Here are important tips for living with this condition:

• Avoid eye rubbing: This is crucial, as rubbing can worsen keratoconus progression
• Manage allergies: Control eye allergies to reduce the urge to rub your eyes
• Protect your eyes: Wear sunglasses to reduce light sensitivity and protect against UV damage
• Follow up regularly: Consistent monitoring helps us track progression and adjust treatment
• Maintain lens hygiene: Proper contact lens care prevents complications
• Report changes: Contact us immediately if you notice vision changes or discomfort
