Advancements in Contact Lenses for Keratoconus: Scleral and Hybrid Lenses

Keratoconus is a progressive eye condition in which the normally round cornea thins and bulges into a cone-like shape. This irregular shape causes distortion and blurred vision, making it challenging for the eye to focus light properly. Keratoconus typically begins in the teenage years or early 20s and can continue to progress for 10-20 years, often leading to significant vision impairment if left untreated.
 

Common Symptoms of Keratoconus

The primary symptoms of keratoconus include:
 

• Blurred or distorted vision
• Increased sensitivity to glare and light
• Frequent changes in eyeglass or contact lens prescription
• Double vision (monocular diplopia)
• Difficulty driving at night

As the condition progresses, the cornea may also become more irregular in shape, leading to higher-order aberrations that further degrade visual quality.
 

The Importance of Early Diagnosis for Keratoconus

Early diagnosis and proper management of keratoconus are crucial, as the condition can significantly impact your quality of life if left untreated. Regular eye exams and monitoring by an eye care professional are essential to detect keratoconus in its early stages, when treatment options are most effective. With timely intervention, you can often slow or even halt the progression of the disease and preserve your vision.
 

Advanced Treatment Options for Keratoconus

In the past, the primary treatment options for keratoconus were rigid gas permeable (RGP) contact lenses or, in severe cases, corneal transplant surgery. However, in recent years, several advanced treatment modalities have emerged, offering improved visual outcomes and better quality of life for those with keratoconus.
 

Two of the most promising advancements in keratoconus management are scleral contact lenses and hybrid contact lenses. These specialized lens designs can provide exceptional visual acuity, comfort, and stability for individuals with this condition.
 

Exploring Scleral and Hybrid Contact Lenses

Scleral lenses are a type of rigid, gas-permeable contact lens that rests on the sclera (the white part of the eye) rather than the cornea. These lenses are designed to vault over the irregular cornea, creating a smooth, uniform surface that can dramatically improve visual acuity. Scleral lenses offer several key benefits for individuals with keratoconus:
 

• Improved Visual Acuity: The unique design of scleral lenses helps to neutralize the irregular shape of the cornea, providing clearer and more consistent vision.
• Enhanced Comfort: Scleral lenses do not directly touch the cornea, reducing the risk of discomfort and irritation often associated with traditional rigid gas-permeable lenses.
• Increased Corneal Hydration: The space between the cornea and the scleral lens is filled with a saline solution, helping to keep the cornea well-hydrated and promoting overall eye health.
• Stabilization of the Cornea: Scleral lenses can help to stabilize the shape of the cornea, potentially slowing the progression of keratoconus.

In addition to scleral lenses, hybrid contact lenses have also emerged as a highly effective option for managing keratoconus. Hybrid lenses combine a rigid, gas-permeable center with a soft, flexible outer ring, providing the visual clarity of a rigid lens with the comfort of a soft lens.
 

The Process of Getting Fitted for Scleral and Hybrid Lenses

Obtaining scleral or hybrid contact lenses for keratoconus typically involves a comprehensive eye examination and specialized fitting process. Your eye doctor will use advanced imaging technologies, such as corneal topography and aberrometry, to precisely measure the shape and curvature of your eyes. This information is then used to custom-design the lenses to fit your individual needs. Your doctor will work with you to make any necessary adjustments to the lens parameters until you achieve the best possible results.
