Keratoconus is a progressive eye condition that often begins during a person’s teenage years or early adulthood. It is characterized by the thinning of the cornea, the clear front surface of the eye, which gradually bulges outward into a cone shape. This distortion can lead to significant visual impairment if not managed properly. As an eye care specialist in Calgary, we’re here to provide insights into the symptoms, causes, and the latest treatment options available for keratoconus.
Symptoms of Keratoconus
The early stages of keratoconus are often difficult to detect because symptoms can be quite subtle. However, as the condition progresses, symptoms typically become more pronounced, including:
- Blurring and distortion of vision
- Increased sensitivity to light and glare
- Frequent changes in eyeglass prescription
- Difficulty driving at night
If you experience any of these symptoms, it’s important to consult with an eye care professional who can perform specific tests to diagnose the condition.
Causes of Keratoconus
The exact cause of keratoconus is still not fully understood, but it is believed to involve a combination of genetic and environmental factors. Some research suggests that excessive eye rubbing and a history of poorly fitted contact lenses may contribute to its development. There is also evidence that people with certain allergic conditions like asthma and eczema are at higher risk.
Advanced Treatment Options
Fortunately, there have been significant advancements in the treatment of keratoconus over the years. Treatment is usually staged and tailored to the severity of the condition:
- Corneal Cross-Linking (CXL) – This treatment helps to strengthen the corneal tissue to halt the progression of keratoconus. It involves the application of vitamin B2 drops to the cornea, which are then activated by ultraviolet light.
- Customized Contact Lenses – Specialized contact lenses, such as rigid gas permeable lenses or scleral lenses, are often used to correct the irregular cornea and improve vision.
- Corneal Transplant – In severe cases, a corneal transplant may be necessary. This involves replacing the keratoconic cornea with a healthy donor cornea.
Each of these treatments has its own indications and benefits, and the best approach depends on the specific needs and condition of the patient’s eyes.
