Understanding Keratoconus and the Role of Scleral Lenses

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.

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.

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.

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.
