Finding Comfort: Exploring Scleral Lenses for Dry Eye Relief

To explore the benefits of scleral lenses for dry eye relief, it’s important to have a clear understanding of what they are and how they work.

What are Scleral Lenses?

Scleral lenses are large, gas-permeable contact lenses that are specially designed to vault over the entire cornea and rest on the sclera, the white part of the eye. Unlike traditional contact lenses, which sit directly on the cornea, scleral lenses provide a protective cushion of fluid between the lens and the cornea. This unique design offers several advantages, making it an ideal option for individuals with various eye conditions.

Scleral lenses are custom-made to fit each individual’s eye shape and provide a comfortable and secure fit. They are typically larger in diameter than other contact lenses, ranging from 14 to 24 millimeters. The larger size ensures that the lens remains stable on the eye, reducing the chances of dislodgement or discomfort.

How Do Scleral Lenses Work?

The key mechanism behind the effectiveness of scleral lenses lies in their ability to create a reservoir of fluid between the lens and the cornea. This reservoir acts as a liquid bandage, providing constant lubrication and moisture to the ocular surface. By keeping the cornea hydrated, scleral lenses help alleviate the symptoms of dry eye.

When inserting scleral lenses, a saline solution is used to fill the gap between the lens and the cornea. This liquid reservoir creates a smooth and moist environment, reducing friction and irritation that can occur with other types of contact lenses. The fluid also acts as a barrier, protecting the cornea from exposure to air and other irritants.

Furthermore, the space between the lens and the cornea allows for better oxygen permeability, promoting a healthier environment for the eyes. This is particularly beneficial for individuals with dry eyes, as oxygen deprivation can exacerbate the symptoms of dryness and discomfort.

By providing a stable and moist environment for the cornea, scleral lenses offer relief for individuals suffering from dry eye syndrome, keratoconus, and those undergoing post-refractive keratectomy (RK) surgery.

Now that we have a foundational understanding of scleral lenses, let’s explore their specific benefits for dry eye relief in the next section.

How Scleral Lenses Help Manage Keratoconus

Keratoconus is a progressive eye disorder characterized by the thinning and bulging of the cornea, resulting in irregular astigmatism and blurred vision. Standard contact lenses may not provide adequate visual correction due to the irregular shape of the cornea. This is where scleral lenses come into play.

Scleral lenses are larger in diameter compared to traditional contact lenses, and they vault over the entire cornea, resting on the white part of the eye called the sclera. This unique design creates a space between the lens and the cornea, filled with a saline solution. By doing so, scleral lenses effectively bypass the irregularities of the cornea, providing a smooth optical surface for better visual acuity.

The tear reservoir between the lens and the cornea acts as a liquid cushion, improving comfort and reducing friction. This can be particularly beneficial for patients with keratoconus, as the tear film helps to protect the cornea and alleviate symptoms of dryness and irritation.

5 Advantages of Scleral Lenses for Keratoconus Patients
