Scleral lenses are specialized types of corrective eyewear that offer a unique solution for individuals suffering from various eye conditions. Unlike traditional contact lenses that rest directly on the cornea, scleral lenses vault over the entire corneal surface and rest on the sclera, the white part of the eye.

These lenses are larger in diameter, typically ranging from 14 to 24 millimeters, and are designed to create a tear-filled reservoir between the lens and the cornea. This reservoir acts as a protective barrier, providing numerous benefits for those with certain eye conditions.

Understanding Keratoconus and Dry Eye

Keratoconus is a progressive eye disorder characterized by the thinning and bulging of the cornea, the clear front part of the eye. This irregularity in the cornea's shape can lead to distorted vision, sensitivity to light, and, in severe cases, vision loss.

Dry eye is a condition in which the eyes do not produce enough tears, or the tears evaporate too quickly, leading to discomfort, irritation, and visual disturbances. Various factors, such as aging, meibomian gland dysfunction, certain medications, and environmental conditions, can contribute to dry eye.

How Scleral Lenses Work

Scleral lenses are designed to address the unique challenges posed by conditions like keratoconus and dry eye. Here's how they work:
 

1. Vaulting over the Cornea: By vaulting over the entire corneal surface, scleral lenses create a tear-filled reservoir between the lens and the cornea. This reservoir acts as a smooth, regular surface, effectively masking any irregularities in the cornea's shape.

2. Tear Reservoir: The tear reservoir created by scleral lenses serves two primary purposes:

• It provides constant lubrication and hydration to the cornea, alleviating dry eye symptoms.
• It helps neutralize any irregularities in the cornea's shape, resulting in improved vision quality.

3. Customized Fit: Scleral lenses are custom-made for each individual's unique eye shape and condition. This precise fit ensures optimal comfort and visual performance.

Benefits of Scleral Lenses for Keratoconus

For individuals with keratoconus, scleral lenses offer numerous benefits:
 

• Improved Visual Acuity: By creating a smooth, regular surface over the irregular cornea, scleral lenses can significantly improve visual acuity and reduce distortions caused by keratoconus.
• Comfortable Wear: Unlike traditional contact lenses that can cause discomfort or dislodge due to the irregular corneal shape, scleral lenses rest on the sclera, providing a more stable and comfortable fit.
• Protection for the Cornea: The tear reservoir created by scleral lenses acts as a protective barrier, shielding the cornea from potential irritation and trauma.
• Slowing Progression: Some studies suggest that scleral lenses may help slow the progression of keratoconus by maintaining a more regular corneal shape and reducing the need for frequent corneal reshaping procedures.

How Scleral Lenses Provide Relief for Dry Eye

Scleral lenses can be a game-changer for individuals suffering from dry eye syndrome. Here's how they help:
 

• Constant Lubrication: The tear reservoir created by scleral lenses provides a continuous source of lubrication and hydration for the cornea, alleviating the discomfort and irritation associated with dry eye.
• Protection from Environmental Factors: Scleral lenses act as a barrier, shielding the eyes from environmental factors like wind, dust, and dry air, which can exacerbate dry eye symptoms.
• Improved Tear Quality: By trapping the tears between the lens and the cornea, scleral lenses can improve the quality and stability of the tear film, further enhancing eye comfort and vision.
• Reduced Medication Dependency: For some individuals with severe dry eye, scleral lenses may reduce or eliminate the need for frequent eye drops or other medications, providing a more convenient and long-lasting solution.
