Keratoconus: How Scleral Lenses Can Help

Keratoconus is a progressive eye condition that causes the cornea to thin and bulge into a cone-like shape, resulting in distorted vision and discomfort. For those affected by keratoconus, standard contact lenses may not provide the clarity or comfort they need. Fortunately, scleral lenses offer an effective solution. In this guide, we’ll explore how scleral lenses work and why they are the preferred choice for many individuals with keratoconus.

What Is Keratoconus?

Keratoconus is a condition in which the cornea, the clear, dome-shaped surface of the eye, becomes thin and gradually bulges outward into a cone shape. This irregular shape causes light entering the eye to be distorted, leading to blurry or distorted vision. Keratoconus often progresses over time, making vision correction increasingly difficult with traditional glasses or contact lenses.

While the exact cause of keratoconus is unknown, it is believed to be linked to genetic factors, eye rubbing, and underlying medical conditions such as allergies or connective tissue disorders.

How Scleral Lenses Work for Keratoconus

Scleral lenses are a specialized type of contact lens designed to vault over the irregular cornea and rest on the sclera (the white part of the eye). This creates a smooth optical surface, helping to correct the visual distortions caused by keratoconus.

Unlike traditional contact lenses, which sit directly on the cornea, scleral lenses provide a reservoir of fluid between the lens and the cornea. This not only enhances vision but also keeps the cornea hydrated, offering relief from the dryness and irritation often experienced by those with keratoconus.

Why Scleral Lenses Are Ideal for Keratoconus

Scleral lenses offer several key benefits for individuals with keratoconus:

• Improved Vision: Scleral lenses create a smooth refractive surface that compensates for the irregular shape of the cornea, providing clearer vision.
• Enhanced Comfort: By resting on the sclera, the lenses avoid touching the sensitive cornea, resulting in greater comfort, especially for those with severe keratoconus.
• Hydration and Protection: The fluid-filled reservoir keeps the cornea moisturized and helps protect it from irritation, dryness, and further damage.
• Stability: Due to their larger size, scleral lenses offer better stability and don’t shift around as much as smaller lenses, which is important for consistent vision correction.

The Scleral Lens Fitting Process for Keratoconus

Getting fitted for scleral lenses requires a comprehensive contact lens exam. During this exam, your optometrist will take detailed measurements of your cornea and sclera to ensure a custom fit that addresses the unique shape of your eyes.

Once fitted, your optometrist will guide you through the proper steps for inserting, removing, and caring for your scleral lenses. Follow-up appointments are essential to monitor the fit and make any necessary adjustments for optimal vision and comfort.

Are Scleral Lenses Right for You?

If you have been diagnosed with keratoconus and are struggling to achieve clear, comfortable vision with glasses or traditional contact lenses, scleral lenses may be the right solution for you. These lenses provide long-lasting relief and improved vision, making them an excellent option for many keratoconus patients.
