Astigmatism is a common eye condition that can cause blurred or distorted vision. Scleral lenses present an effective solution for individuals with astigmatism, offering clear and stable vision.

What is Astigmatism?

Astigmatism is a condition often present at birth and may occur in combination with other refractive errors. In most cases it is attributed to genetics and the natural shape of the eye.

The symptoms of astigmatism can vary in severity from person to person. Some individuals may not even realize they have the condition because their brain adjusts to the slight blurriness or distortion. However, in more severe cases, astigmatism can cause headaches, fatigue, eyestrain, and difficulty seeing at night, which can significantly impact a person's quality of life.

What are Scleral Lenses?

Scleral lenses are a type of gas permeable (GP) contact lens that are larger in diameter than standard GP lenses and designed to vault over the entire corneal surface, resting comfortably on the white part of the eye, known as the sclera. The name "scleral" lens stems from the fact that these lenses rest on the sclera, creating a tear-filled vault over the cornea.

How Scleral Lenses Work for Astigmatism

Scleral lenses for astigmatism work by replacing the eye's irregular front surface with a perfectly smooth, artificial one. This helps to correct refractive errors by ensuring that light entering the eye is appropriately focused onto the retina, leading to clearer vision.

The unique design of scleral lenses creates a fluid reservoir between the lens and the cornea. This pool of tear fluid works to neutralize the irregularities on the cornea's surface, effectively masking astigmatism. Because scleral lenses vault over the cornea without actually touching it, they also offer a high level of comfort, even for those with sensitive eyes.

The Benefits of Scleral Lenses

The primary benefit of scleral lenses for astigmatism is the potential for clear, stable vision. Thanks to their unique design and customized fit, these lenses can offer superior visual acuity compared to traditional contact lenses or glasses. This is especially true for people with high levels of astigmatism or other corneal irregularities.

Additionally, scleral lenses also offer a high level of comfort. Because they rest on the sclera and vault over the cornea, they do not cause the dryness, discomfort, or irritation often associated with other types of contact lenses.

Lastly, scleral lenses can improve the health of the eye. The tear-filled vault they create not only aids in vision correction but also helps to keep the eye hydrated and protected. This makes them a beneficial choice for those with dry eyes or other corneal conditions, providing both vision correction and therapeutic benefits.

Achieving Clear and Stable Vision through Scleral Lenses

Scleral lenses also offer superior comfort and stability, making them a feasible option even for those who have struggled with other types of contact lenses in the past. The additional benefits of improved eye health and hydration further validate their position as an excellent choice for vision correction.
