Keratoconus and Contact Lenses: Finding the Perfect Fit

(972) 378-0707

Understanding Keratoconus: A Vision Disorder

Your cornea, the clear, round, front surface of your eye, is the first ocular tissue that light passes through on its way to the retina. Keratoconus causes the cornea to thin, steepen, and form an irregular cone-shape. This transformation causes light to focus on the retina incorrectly, which leads to distorted vision.

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

Causes and Risk Factors: Can it Damage Your Vision?

The precise cause of keratoconus remains unknown. Researchers believe that some individuals may have a genetic predisposition to the condition.

However, several factors have been associated with the development of keratoconus:

Family History: If a family member has been diagnosed with keratoconus, there is an increased likelihood of inheriting the condition. If you have keratoconus, it is advisable to have your children's eyes examined for early signs, by the age of 10 at the latest. Early detection of keratoconus is crucial for successful management and prevention of severe disease.

Certain Medical Conditions: Research has indicated a correlation between keratoconus and systemic conditions such as Down syndrome, Ehlers-Danlos syndrome, osteogenesis imperfecta, retinitis pigmentosa, sleep apnea, Lebers congenital amaurosis, Marfan’s, and other connective tissue disorders.Inflammation: Inflammatory conditions like allergies, asthma, or atopic eye disease have the potential to weaken the corneal tissue over time.

Eye Rubbing: Vigorous and persistent eye rubbing can lead to corneal damage. Excessive eye rubbing can accelerate its progression for individuals already diagnosed with keratoconus.


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.

This sounds crazy, but Dr. Pang and his staff seriously changed my life for the better. Went in for ... a routine exam. Dr. Pang was so thorough, he realized I had a condition that would be greatly improved by prism glasses. I had no idea so many of the physical challenges I was experiencing were a result of my vision. Cannot thank them enough. The world would be a different place if all doctors were this caring and thorough.

I have been a patient of Dr. Peng for 5 years. Having never worn glasses before, the process seemed ... daunting. I came to Trinity with mysterious vertigo no other doctor could address. Dr. Peng diagnosed me and soon my life became clear again! The staff at Trinity made my transition to wearing glasses smooth through their patience and kindness. Dr. Peng is unwavering in his dedication to his patients. His expertise is unmatched. Personalized service from people who obviously care and love their craft is rare today. Do not hesitate to schedule an appointment at Trinity.

I have been a patient at Trinity Eye Care for about 20 years now -- my first visit was when I was 5,... and now I'm 26! Throughout all of my visits, everyone has been so kind, attentive and just all-around helpful. This is the only place where I've gotten my night/hard contacts, day/soft contacts and glasses (prescription and blue-light). Even though I now live in another city, I still visit Plano for my annual checkups. Moreover, my parents are also still patients! I don't foresee switching providers... ever. ◡̈
