Keratoconus and Contact Lenses: Finding the Perfect Fit

What Are the Symptoms of Keratoconus?

There are two primary ways keratoconus affects your vision, and it shows up as:

• Irregular Astigmatism: The cornea, which typically has a smooth spherical shape, undergoes a transformation into a cone-like structure. This alteration results in a wavy and uneven corneal surface, known as irregular astigmatism.
• Nearsightedness: As the front part of your eye expands, your vision becomes increasingly nearsighted. This means that you can only see objects clearly when they are up close (however in keratoconus, even objects at near may still appear distorted). Anything at a distance appears blurry.
• Variable or quickly changing vision. The inability to achieve clear vision in glasses or soft contacts when it had been possible in the recent past.

Recognizing the signs of keratoconus is essential, as early detection can lead to more effective treatment. Keep an eye out for the following symptoms:

• Double or triple vision when using just one eye
• Blurriness of objects both near and far
• Perception of bright lights with halos around them
• Presence of light streaks
• The presence of ghost images
• Persistent blurry vision that affects your ability to drive safely

Scleral Lenses for Keratoconus: The Game-Changer

Keratoconus presents a unique challenge when it comes to vision correction. Traditional gas permeable? contact lenses often prove ineffective as they cannot conform to the irregular corneal shape. This is where scleral lenses step in as an innovative solution.

Here are four compelling reasons to consider scleral lenses for keratoconus:

• Enhanced Comfort

  Scleral lenses are larger in diameter compared to traditional rigid gas permeable contact lenses, spreading their weight across a broader, less sensitive area, ensuring comfort during extended wear.

• Improved Vision

  Unlike glasses, which often offer limited visual improvement for keratoconus patients, scleral lenses can significantly enhance vision clarity and stability.

• Constant Moisture

  Scleral lenses provide a continuous reservoir of moisture between the lens and the eye's surface, ensuring a soothing and moisture-rich environment for the eyes.

• No More Eye Rubbing

  The design of scleral lenses minimizes the need for eye rubbing by reducing inciting factors of ocular surface and lid inflammation due to allergy response, reducing the risk of further corneal damage and discomfort.
