Scleral Lenses for Keratoconus: A Complete Guide

Keratoconus is a progressive eye condition that causes the cornea to thin and bulge, resulting in distorted vision and discomfort. For individuals with keratoconus, finding an effective vision correction solution can be challenging. Scleral lenses are an advanced option that not only corrects vision but also provides comfort for those with irregular corneas. In this comprehensive guide, we’ll explore how scleral lenses work, their benefits, and why they are an ideal choice for managing keratoconus.

What Is Keratoconus?

Keratoconus is a degenerative condition in which the cornea, the clear, dome-shaped surface of the eye, becomes progressively thinner and bulges into a cone shape. This irregular shape causes light entering the eye to be distorted, leading to blurred or distorted vision. As keratoconus progresses, it becomes increasingly difficult to correct vision with glasses or traditional contact lenses.

Common symptoms of keratoconus include blurry vision, sensitivity to light, eye strain, and frequent changes in eyeglass prescriptions. While the exact cause is unknown, genetics, excessive eye rubbing, and environmental factors are believed to play a role in its development.

How Scleral Lenses Help with Keratoconus

Scleral lenses are a specialized type of contact lens that vaults over the cornea and rests on the sclera, the white part of the eye. This design allows the lens to provide a smooth, even surface for light to pass through, correcting the distorted vision caused by keratoconus.

The space between the lens and the cornea creates a tear-filled reservoir, which not only improves vision but also keeps the cornea hydrated and protected from irritants. This makes scleral lenses a comfortable option for individuals with keratoconus who may also suffer from dry eyes or corneal sensitivity.

Benefits of Scleral Lenses for Keratoconus

Scleral lenses offer several advantages over traditional contact lenses, particularly for individuals with keratoconus:

• Superior Vision Correction: Scleral lenses provide a stable, smooth refractive surface, greatly improving vision for patients with irregular corneas.
• Enhanced Comfort: Because scleral lenses rest on the sclera rather than the sensitive cornea, they offer a more comfortable wearing experience, especially for those with keratoconus.
• Hydration and Protection: The tear-filled reservoir helps to keep the cornea moist, reducing dryness and protecting the cornea from further damage or irritation.
• Stability: The larger size of scleral lenses ensures they stay in place throughout the day, providing consistent vision correction without the discomfort or movement often associated with smaller lenses.

The Scleral Lens Fitting Process

The fitting process for scleral lenses is more detailed than with standard contact lenses. It begins with a comprehensive eye exam to assess your overall eye health and determine if scleral lenses are the best option for your condition.

Your optometrist will then use advanced tools like corneal topography to measure the shape of your cornea and sclera. Based on these measurements, custom scleral lenses will be created to fit your eyes perfectly. During follow-up appointments, the lenses will be adjusted to ensure optimal fit, comfort, and vision clarity.

Who Is a Good Candidate for Scleral Lenses?

Scleral lenses are an excellent choice for individuals with keratoconus who struggle with traditional contact lenses or glasses. They are particularly beneficial for those with:

• Advanced Keratoconus: Patients whose keratoconus has progressed to the point where glasses or standard lenses no longer provide adequate vision correction.
• Dry Eye Syndrome: Individuals with keratoconus who also experience dry eyes may find relief with scleral lenses, which keep the cornea hydrated throughout the day.
• Corneal Scarring: Scleral lenses can provide comfort and vision correction for patients with scarring or damage to the cornea due to keratoconus.
