Understanding Keratoconus and the Role of Scleral Lenses

(708) 229-2200

What is Keratoconus?

Kerataconus is a condition that affects the cornea, the clear front part of the eye. Although it might sound intimidating, understanding keratoconus and its available treatments can help you or someone you know find proper treatment and maintain clear vision.

At Advanced Eye Care Professionals, we help patients with keratoconus achieve clear, comfortable, and healthy vision using scleral contact lenses. Contact us to schedule your appointment if you or someone you love has been diagnosed with a corneal condition.

Keratoconus is an eye condition where the cornea, which is normally round and dome-shaped, becomes thin and develops a cone-like bulge. This irregular shape affects the cornea's ability to properly focus light onto the retina, resulting in blurry and distorted vision.

Causes of Keratoconus

While the exact cause of keratoconus is still not fully understood, it is believed to be a combination of genetic and environmental factors. If you have a family history of keratoconus, you may be at a higher risk of developing the condition. Frequent eye rubbing, chronic eye irritation, and certain underlying conditions, such as allergies, can also contribute to its development.


Symptoms of Keratoconus

Keratoconus typically starts during the teenage years and gradually progresses over time. The following symptoms may indicate the presence of keratoconus:

  • Blurred or distorted vision: Objects may appear distorted, and it can become increasingly difficult to see clearly even with corrective lenses.
  • Increased sensitivity to light: Bright lights may cause discomfort and glare.
  • Halos and ghosting: Seeing halos or ghosting around lights, especially at night.
  • Eye strain and fatigue: Eyes may feel tired or strained, especially after focusing on objects for extended periods.

Treatment Options for Keratoconus

Several treatment and corrective options are available for keratoconus. The choice of treatment depends on the severity of the condition and the individual's specific needs. The options include:

  • Glasses or contact lenses: In the early stages, regular glasses or soft contact lenses may be sufficient to correct vision. However, as the condition progresses, specialized lenses become necessary.
  • Hybrid lenses: Hybrid lenses combine the features of rigid and soft lenses. They have a rigid center for clear vision and a soft outer ring for increased comfort.
  • Corneal cross-linking (CXL): This treatment aims to strengthen the cornea using a combination of riboflavin eye drops and ultraviolet light. CXL can help slow down the progression of keratoconus.
  • Scleral lenses: Scleral lenses are becoming increasingly popular for managing keratoconus due to their unique design, comfort, and optical clarity.

Scleral Lenses: A Promising Solution at Advanced Eye Care Professionals

Scleral lenses are large, rigid lenses that vault over the cornea, resting on the sclera (the white part of the eye). Unlike traditional contact lenses, which sit directly on the cornea, scleral lenses create a tear-filled space between the lens and the cornea. This reservoir of fluid acts as a protective barrier, keeping the cornea hydrated and providing a smooth optical surface for improved vision.

How Do Scleral Lenses Work?

When a person with keratoconus wears scleral lenses, the lens creates a uniform surface over the irregular cornea. This helps to reduce distortions and provide clearer vision. The liquid reservoir also moisturizes the cornea, reducing dryness and discomfort. In fact, some studies have found that patients with keratoconus who consistently wear scleral lenses have a much lower chance of needing a corneal transplant. This is due largely to the fact that scleral lenses protect the cornea and shield it from irritation due to blinking and other factors.

Scleral lenses are custom-made for each individual's eye shape and condition. They are highly durable and can usually be worn for longer periods without discomfort.

Effective Keratoconus Treatment at Advanced Eye Care Professionals

Living with keratoconus can be challenging, but with the right understanding and treatment, individuals can achieve improved vision and a better quality of life. While various treatment options exist, scleral lenses have gained recognition for their ability to address the unique needs of those with keratoconus.

If you suspect you may have keratoconus or know someone who does, consult an eye care professional at Advanced Eye Care Professionals who can guide you through the available treatment options, including the potential benefits of scleral lenses. Remember, early detection and intervention are key to managing this condition effectively.


Keratoconus FAQs

Can keratoconus be prevented?

Currently, there is no known way to prevent keratoconus. However, avoiding excessive eye rubbing and taking steps to maintain good overall eye health may help reduce the risk of progression.

Can scleral lenses be uncomfortable to wear?

While it may take some time to adjust to wearing scleral lenses, they are designed for comfort and improved vision. The liquid reservoir between the lens and the cornea helps keep the eyes hydrated, reducing discomfort often associated with other types of lenses.

I’ve been a loyal patient of Dr. Casey Hogan for over 25 years, and I’ve been a client at Advanc... e Eyecare Professionals since the very day it opened. Simply put, this practice is top-notch, and I wouldn’t trust my eye care to anyone else. From the moment you walk in, you’re greeted by the friendly, welcoming staff who always make you feel like part of the family. They are efficient and thorough in explaining your insurance coverage and any charges upfront, so there are never any surprises. The entire office operates with professionalism and respect for your time, making each visit smooth and seamless. Dr. Hogan is the heart of this practice. She is not only incredibly knowledgeable but also genuinely cares about her patients. She takes the time to explain every aspect of your eye health in a way that’s easy to understand, answering all questions with patience and clarity. Her warmth and attention to detail make it clear that she’s deeply committed to providing the best care possible. I can’t imagine anyone leaving her office without feeling fully informed and well-cared for. To me, Dr. Hogan exemplifies what an excellent doctor should be—skilled, compassionate, and dedicated to her patients' well-being. It’s rare to find a healthcare provider who combines such expertise with a personal touch, and I’m grateful to have found Dr. Hogan and Advance Eyecare Professionals all those years ago. Honestly, the only person who could possibly have an issue with Dr. Hogan is someone who can’t see the incredible care she provides!
