Clear vision is something we all value in Australia, whether it’s to enjoy the city skyline of Brisbane or the natural beauty that surrounds us. However, for some, a progressive eye condition called keratoconus can gradually steal that clarity, causing blurred and distorted vision. If you’ve noticed your eyesight worsening, or if terms like “keratoconus symptoms” or “keratoconus treatment Brisbane” have been in your recent search history, this guide is for you.
Keratoconus is more common than many realise, and thankfully, advancements in ophthalmology mean that effective treatments are readily available right here in Brisbane. In fact, Brisbane surgeons have pioneered some keratoconus treatments – Dr Brendan Cronin is considered a world leader in Keratoconus.
What is Keratoconus? Unmasking the “Cone-Shaped Cornea”
So, what is keratoconus? In simple terms, keratoconus is a progressive eye disease that affects the cornea – the clear, dome-shaped front surface of your eye. A healthy cornea is round, allowing light to focus correctly onto the retina for clear vision. In individuals with keratoconus, the cornea gradually thins and begins to bulge outwards, forming a cone-like shape. This corneal thinning and irregular shape disrupts the normal focusing of light, leading to a range of vision problems.
The exact cause of keratoconus isn’t fully understood, but genetics, environmental factors (like excessive eye rubbing, often linked to allergies), and certain systemic conditions are thought to play a role. It typically starts in the teenage years or early twenties and can progress for 10-20 years before stabilising.
Keratoconus symptoms often start subtly but can worsen over time. These include:
- Increasingly blurred vision
- Distorted vision, where straight lines may appear wavy
- Increased sensitivity to light and glare (light sensitivity)
- Seeing halos or ghosting around lights, especially at night
- Frequent changes in glasses or contact lens prescriptions
- Developing or worsening nearsightedness and astigmatism
If you’re experiencing any of these symptoms, seeking a keratoconus diagnosis from an eye specialist in Brisbane is crucial. Early detection can lead to more effective management and help preserve your vision. Diagnosis often involves a detailed eye examination and corneal topography, a specialised mapping technique that shows the curvature of your cornea.
Navigating Keratoconus Treatment Brisbane: Modern Solutions for Clearer Sight
While there’s no cure for keratoconus, various treatments can slow or halt its progression, improve vision, and enhance quality of life. Brisbane offers a range of cutting-edge keratoconus treatment options:
- Corneal Collagen Cross-Linking (CXL) Often the first line of defence for progressive keratoconus, corneal collagen cross-linking Brisbane (commonly known as CXL) is a minimally invasive procedure designed to strengthen the cornea. The treatment involves applying riboflavin (vitamin B2) eye drops to the cornea, which are then activated by a controlled dose of ultraviolet (UV) light. This process creates new bonds, or “cross-links,” between the collagen fibres within the cornea, making it stiffer and more resistant to further bulging. CXL can effectively stop the progression of keratoconus, particularly in its early to moderate stages, preventing further vision loss. Many patients in Brisbane have benefited from CXL, stabilising their condition.
- Contact Lenses for Keratoconus For many with keratoconus, standard glasses or soft contact lenses don’t provide adequate vision correction due to the irregular corneal surface. Specialty contact lenses for keratoconus are a cornerstone of visual rehabilitation. Options available include:
-
- Scleral lenses: Larger diameter lenses that vault over the entire cornea, resting on the white part of the eye (the sclera). They offer excellent comfort and stable vision, even for advanced keratoconus.
- Hybrid lenses: These combine a rigid centre for crisp optics with a soft peripheral skirt for comfort. A Brisbane optometrist specialising in keratoconus can help determine the best contact lens option for your specific needs.
Topography-Guided Phototherapeutic Keratectomy (TG-PTK) For some patients, particularly those with corneal surface irregularities or mild scarring, topography-guided phototherapeutic keratectomy (TG-PTK) can be an option, often performed in conjunction with or after CXL. This advanced laser procedure uses detailed corneal topography maps to guide the excimer laser in selectively smoothing the corneal surface. The aim is not necessarily to correct all the refractive error but to make the cornea more regular, which can improve the quality of vision and make contact lens wear more comfortable or even allow for satisfactory vision with glasses in some cases. It’s a highly customised treatment aimed at improving the optical quality of the cornea.
Corneal Allogenic Intrastromal Ring Segments (CAIRS) A newer, innovative treatment for keratoconus gaining traction is CAIRS (Corneal Allogenic Intrastromal Ring Segments). This minimally invasive corneal transplant procedure involves implanting small segments made from donor corneal tissue into the stroma (the middle layer) of the patient’s cornea. These segments help to flatten the steep cone, reshape the cornea, and improve its regularity. CAIRS offers a biocompatible alternative to synthetic ring segments, potentially reducing risks like extrusion or inflammation. This technique can improve vision and make contact lens fitting easier for suitable candidates. Brisbane ophthalmologists at the forefront of corneal care are increasingly offering advanced options like CAIRS keratoconus treatment.
In more advanced cases, or if other treatments are not sufficient, a Deep Anterior Lamellar Keratoplasty “DALK” or Penetrating Keratoplasty “PK” Full thickness corneal transplant may be considered. However, the goal of modern keratoconus management is to intervene earlier with treatments like CXL and advanced contact lenses to avoid or delay the need for transplantation.
