Scleral Contacts
What Are Scleral Contact Lenses?
Scleral contact lenses, sometimes referred to simply as "sclerals," are large, gas-permeable lenses that cover a significant portion of the eye's surface, including the entire cornea and part of the sclera (the white part of the eye). Unlike traditional contact lenses that sit directly on the cornea, scleral lenses vault over the cornea, creating a tear-filled chamber between the lens and the eye's surface. Believe it or not, they are extremely comfortable.
How Do Scleral Contact Lenses Work?
Scleral contact lenses have revolutionized the field of vision correction and eye care. They offer improved visual acuity, comfort, and protection for individuals with a wide range of eye conditions. Whether you're dealing with an irregular cornea or seeking a solution for your refractive error, these specialty contact lenses provide a versatile and effective option.
Improved Visual Clarity
Scleral lenses are primarily used for two main purposes:
Correcting refractive errors such as myopia or hyperopia
Providing relief for symptoms of certain eye conditions
By providing a smooth, clear optical surface that compensates for irregularities in the cornea's shape, these lenses offer users improved visual acuity and reduced aberrations.
Protecting the Cornea
Scleral lenses are particularly beneficial for individuals with corneal irregularities, such as keratoconus or severe dry eye syndrome. By creating a tear reservoir between the lens and the cornea, these lenses provide constant hydration and protection. This not only enhances comfort but also promotes the healing of damaged corneal tissue.
Stable Fit
One of the most significant advantages of permeable lenses is their stability on the eye. Traditional contact lenses can shift or rotate during blinking, causing discomfort and inconsistent vision. Scleral lenses, on the other hand, stay firmly in place, ensuring a consistent and stable visual experience.
Customization
Modern scleral lenses are highly customizable to suit each individual's unique eye shape and prescription requirements, ensuring maximum comfort and clearer vision. Eye care professionals use specialized equipment to measure the eye's curvature and design lenses that provide a perfect fit.
Protection from Environmental Factors
Scleral lenses act as a barrier between the eye and external factors, such as dust, allergens, and wind. This can be particularly beneficial for individuals with sensitive eyes or those who spend extended periods in challenging environments, such as windy outdoor activities or air-conditioned offices.
What Makes Scleral Contact Lenses Different From Standard Contact Lenses?
Scleral contact lenses are larger than standard contacts and rest on the sclera instead of the cornea, creating a tear-filled reservoir that provides sharper vision, enhanced comfort, and protection for irregular or sensitive corneas. Their stable, customized fit makes them especially beneficial for people with eye conditions where traditional lenses may not offer adequate results.
What Conditions Can Scleral Lenses Treat?
These lenses are often used for conditions where standard lenses may not work effectively, including:
Corneal Irregularities: Ideal for conditions like keratoconus, dry eye syndrome, and corneal ectasia, where the smooth lens surface and fluid reservoir provide clearer, more comfortable vision.
Refractive Errors: Can provide clear vision for patients with myopia, hyperopia, and astigmatism
Autoimmune Conditions: Provides relief and protection for those with conditions like Stevens-Johnson Syndrome and Sjören's Syndrome that can cause severe dryness and sensitivity.
Allergies & Sensitivities: Helps shield eyes from allergens and reduce irritation.
Eye Injuries: Improves vision and comfort for patients with corneal scarring and post-surgical vision problems by creating a protective barrier over the corneal surface.
