Scleral Lenses for Astigmatism: Achieving Stable, Clear Vision

Scleral lenses are specialized contact lenses designed to vault over the cornea and rest on the white part of the eye. They create a stable, tear-filled chamber that provides clear vision and comfort for patients with astigmatism, even in complex cases.

Understanding Astigmatism

Astigmatism is a common vision condition caused by an irregular shape of the cornea or lens in the eye. This irregular shape causes blurry or distorted vision at any distance.

What Causes Astigmatism?

Astigmatism happens when the front surface of your eye, the cornea, or the lens inside the eye is shaped more like a football than a basketball. This uneven shape causes light to focus improperly on the retina, leading to blurred vision.

Common Symptoms

People with astigmatism may experience:

  • Blurry or distorted vision
  • Eye strain or fatigue
  • Headaches
  • Squinting to see clearly

How Astigmatism Is Measured

During an eye exam, your doctor uses specialized tools like corneal topography to map the shape of your cornea and measure how light bends in your eye. This helps determine the precise correction needed for your vision.

Regular vs. Irregular Astigmatism

Regular astigmatism has a predictable curve that can often be corrected with glasses or standard contacts. Irregular astigmatism, which can result from eye conditions like keratoconus or corneal scarring, requires a more custom solution like scleral lenses.

What Are Scleral Lenses?

Scleral lenses are large, gas-permeable contact lenses that vault over the entire cornea and rest gently on the white part of the eye, called the sclera. They hold a protective layer of tears between the lens and the eye’s surface.

Design and Structure

Scleral lenses are larger than standard lenses, usually measuring between 14.5 and 24 millimeters across. This size allows them to form a smooth, tear-filled space over the cornea, providing a new refractive surface for the eye.

How They Differ from Other Lenses

Unlike soft lenses that sit directly on the cornea, scleral lenses float on a cushion of tears. This makes them more stable on the eye, reducing movement and providing steadier vision throughout the day.

Breathable Materials

Made from high-quality, gas-permeable materials, scleral lenses allow plenty of oxygen to reach the cornea. This is essential for keeping your eyes healthy and comfortable during extended wear.

Benefits of Scleral Lenses for Astigmatism

Scleral lenses provide clear vision, enhanced comfort, and protection for the ocular surface, especially for patients whose astigmatism is difficult to correct with other options.

Sharper, Stable Vision

The fluid layer under the lens neutralizes corneal irregularities and masks distortions caused by astigmatism. This results in sharper, more stable vision for daily tasks, whether near or far.

Soothing Dry Eyes

The tear-filled space under the lens continuously hydrates the eye's surface. This helps soothe dry or irritated eyes, providing significant relief to patients who also have dry eye symptoms.

All-Day Comfort

Scleral lenses are designed to stay comfortably in place for 12 hours or more. Their fit on the less sensitive sclera minimizes lens awareness, allowing patients to wear them throughout the day with ease.

Custom Fit for Irregular Corneas

Patients with corneal scars, keratoconus, or post-surgical changes benefit from scleral lenses because they are customized to precisely fit unique eye shapes and correct irregular astigmatism more effectively than other lenses.

The Fitting Process

The Fitting Process

Getting the right scleral lenses requires careful measurement and several visits to ensure the best possible fit, comfort, and vision.

Initial Evaluation

Your eye doctor performs a detailed eye exam, checking your vision, overall eye health, and tear quality to determine if you are a good candidate for scleral lenses.

Corneal Scanning and Imaging

Advanced technology, such as a corneal topographer, is used to create a detailed map of your eye’s surface. This map guides the design of your custom-fit lenses.

Trial Lens Placement

During your fitting, trial lenses are placed on your eyes. Your doctor will then check the fit, the thickness of the tear layer, and your vision to make sure the lens is performing correctly.

Lens Adjustments and Customization

Based on the trial fitting, the lens parameters may be adjusted to improve comfort and vision. The final lenses are then custom-ordered from a specialized lab.

Insertion and Removal Training

You will receive one-on-one training on how to safely fill, insert, and remove your scleral lenses using the recommended techniques and simple tools.

Caring for Scleral Lenses

Proper cleaning, handling, and storage are essential to keep your scleral lenses in good condition and protect your eye health.

Daily Cleaning and Disinfection

Use the cleaning and disinfecting solutions recommended by your doctor to remove deposits. Never use tap water, as it can contain microorganisms that cause serious eye infections.

Proper Storage

Lenses should be stored overnight in a clean case filled with fresh, preservative-free saline or a recommended solution. You should replace your lens case at least every three months.

Safe Handling Tips

To handle your lenses safely:

  • Always wash your hands thoroughly before touching your lenses.
  • Handle lenses gently to avoid scratches or damage.
  • Use a lens plunger or other recommended tools to insert and remove lenses.

Regular Check-Ups

Routine follow-up appointments allow your eye doctor to monitor the lens fit and your eye health, ensuring you continue to have optimal comfort and vision.

Potential Risks and Solutions

Potential Risks and Solutions

While scleral lenses are very safe and effective, some common issues may occur. Understanding these helps you and your doctor address concerns promptly.

Lens Discomfort

Some patients feel the lens initially. If discomfort persists, your doctor can adjust the fit. A gradual break-in schedule often helps improve comfort within a few days.

Bubbles or Fogging

Air bubbles trapped under the lens or debris in the tear reservoir can cause blurry or foggy vision. Proper filling techniques can reduce bubbles, and your doctor may recommend different solutions to prevent fogging.

Redness or Irritation

If you experience redness, it could be due to overwear, a reaction to a solution, or a fit issue. Using preservative-free saline and following your wear schedule can help. If redness persists, contact your eye doctor.

Next Steps

If astigmatism affects your vision or comfort, talk to your eye care provider to see if scleral lenses are the right choice for you. A personalized fitting can help you achieve the clear, comfortable vision you deserve.
