If you struggle with high astigmatism, finding a comfortable solution to achieve clear vision is essential. Scleral lenses provide a unique and effective approach for those seeking relief from blurry sight associated with irregular corneas. At Insight Vision Center Optometry, our eye doctors are ready to guide you through the benefits and personalized fitting of scleral lenses, ensuring you can enjoy everyday activities with renewed clarity.

Understanding High Astigmatism and Its Impact on Vision

Astigmatism occurs when the natural curvature of the eye is irregular, so that light does not focus evenly on the retina. High astigmatism can blur vision for both near and distant objects, making everyday activities like driving, reading, or simply recognizing faces a real challenge.

When the cornea or lens surface does not have a uniform curve, it disrupts how light is focused. In patients with high astigmatism, traditional soft contact lenses may not always provide the clarity required because they conform too readily to the irregular surface. This is where scleral lenses excel, they create a new, regular optical surface that directs light precisely onto the retina, enabling our eye doctors to help you achieve stable and clear vision.

How Scleral Lenses Work for High Astigmatism

Scleral lenses are large-diameter hard lenses that rest on the sclera, the white outer wall of the eye, rather than directly on the cornea. This design is key to their effectiveness. By vaulting over the cornea, scleral lenses create a fluid-filled reservoir that fills in the irregularities and provides a new smooth surface for light focusing. Here’s the thing: that reservoir not only neutralizes the refractive error but also keeps your eyes comfortably hydrated throughout the day.

The Science Behind Comfort and Clarity

Irregular Astigmatism and Lens Rigidity

Let’s break it down further. High astigmatism results from the irregular shape of the cornea or lens. In some cases, the eye may exhibit irregular astigmatism, making it even more challenging for standard lenses to deliver adequate sharpness. Scleral lenses overcome these challenges by maintaining their rigid shape, regardless of the underlying corneal contour.

Tear Fluid Reservoir Benefits

Furthermore, the tear fluid trapped between the lens and the cornea creates a protective cushion. This fluid reservoir not only corrects imperfections by forming an even refractive surface but also contributes significantly to the comfort of the lens throughout long hours of wear. It’s like having a built-in moisturizer for your eyes, which is especially beneficial for patients who suffer from dry eye symptoms.

Key Advantages of Scleral Lenses in Managing High Astigmatism

Scleral lenses offer several important advantages for those dealing with high astigmatism:

Stable Vision

Because these lenses vault over the irregular surface of the cornea and sit firmly on the sclera, they do not shift as much as other lens types. This ensures consistent, blur-free vision.

Superior Comfort

The protective tear reservoir reduces irritation and provides continuous lubrication, which is especially helpful for individuals with dry eye symptoms.

Custom Fit

Each lens is designed to match your unique eye shape, meaning that the correction is tailored just for you. This customization is critical for patients with irregular or high astigmatism, providing them with crystal-clear vision and comfort that regular contact lenses cannot match.

Effective Correction of Both Regular and Irregular Astigmatism

Whether your astigmatism is due to a naturally occurring oval-shaped cornea or more complex irregularities caused by conditions like keratoconus or post-surgical changes, scleral lenses are engineered to compensate for and correct these distortions effectively.

Who Can Benefit from Scleral Lenses?

Individuals with High or Irregular Astigmatism

When traditional lenses fail to adequately correct the refractive error due to significant corneal irregularities, scleral lenses provide a stable alternative that corrects vision.

Patients with Keratoconus or Corneal Ectasia

These conditions cause the cornea to thin or bulge. Here, scleral lenses create a new front optical surface that minimizes distortion and improves visual clarity.

Post-Surgical or Trauma Patients

After procedures such as LASIK, corneal transplants, or injuries, the eye’s surface can be irregular, making standard lenses difficult to fit. Scleral lenses avoid direct contact with these sensitive areas, offering soothing yet effective vision correction.

People with Dry Eye Syndrome

The fluid reservoir of scleral lenses continuously bathes the cornea with moisture, helping to alleviate the discomfort associated with dry eyes and enhancing overall eye health.

If you belong to any of these groups or have experienced discomfort with other lens types, it’s worthwhile to explore whether scleral lenses are the right solution for you.

The Fitting Process: A Personalized Journey to Better Vision

One of the most significant benefits of scleral lenses is the customization process. Our eye doctors begin with a thorough consultation and eye examination, utilizing advanced imaging techniques like corneal topography and scleral profilometry. This meticulous evaluation ensures that the lens fits perfectly and functions ideally.

Steps in the Fitting Process

The fitting process typically includes the following key steps:

Comprehensive Eye Examination: Cutting-edge imaging using advanced technology such as corneal topography are used to map the unique contours of your eye. This technology helps identify the precise dimensions and curvatures that need correction.
Trial Lens Fitting: During the fitting session, a series of trial lenses are placed on your eye to assess the initial comfort and visual acuity. This trial period is critical for making the necessary adjustments.
Customized Adjustments: Once the trial lenses provide acceptable performance, our eye doctors customize the final lenses to perfectly match your eye’s shape, ensuring optimal fluid reservoir formation and stability throughout the day.

Patient Follow-Up

Your comfort and satisfaction remain our top priority during this process. Many patients find that an initial adjustment period is necessary, but with regular follow-up appointments, any minor discomfort can be quickly addressed and fine-tuned.

A Closer Look at the Visual Benefits

Overall Quality of Life Impact

Clear, stable vision is not merely about improved eyesight—it enhances your overall quality of life. With seamless vision correction, everyday activities become more enjoyable and less stressful. This is particularly important for those with high astigmatism, where even minor fluctuations in lens positioning can cause blurry or distorted vision.

Mechanism of Clarity

Scleral lenses deliver a significant advantage by providing a consistent refractive surface. The tear-filled space created by the lens design acts as a natural buffer against corneal irregularities, ensuring the light is uniformly focused on the retina. This not only results in sharper vision but also minimizes distortions that can lead to eye strain and headaches.

Everyday Life Impact

Imagine being able to see the details of a busy street sign or enjoy a scenic view without the constant worry that your vision might blur with each blink. That’s the difference scleral lenses can make, providing reassurance and clarity in your day-to-day life.

Comfort and Moisturization Benefits

One of the standout aspects of scleral lenses is their focus on maintaining a comfortable environment for your eyes. The design creates a fluid reservoir between the lens and the cornea.

Comparing Scleral Lenses with Other Contact Lens Options

Standard Soft Lenses– Soft lenses are popular for their ease of use; however, they conform to the cornea’s shape. For individuals with irregular or severe astigmatism, this conformity means that the underlying irregularities are not corrected, potentially resulting in blurred or unstable vision.

Rigid-Gas Permeable (RGP) Lenses-RGP lenses can provide excellent vision by maintaining their shape, but they are typically smaller and rest on the cornea. This can lead to discomfort and a longer adaptation period, especially for those who have a history of wearing soft contacts. In contrast, the larger design of scleral lenses often enhances both comfort and visual stability.

Hybrid Lenses-Hybrid lenses combine the clarity of a rigid center with the comfort of a soft skirt. While they may work well for some patients, they still might not deliver the same level of stability or hydration provided by scleral lenses, particularly for high astigmatism cases.

Is the Investment Right for You?

Cost and Benefit Consideration– We know that cost and adjustment concerns are important considerations when deciding on any vision correction method. While the price point for custom scleral lenses is higher than standard options, many patients find that the benefits—improved clarity, enhanced comfort, and long-lasting performance—provide excellent value over time.

Lifestyle Considerations– Consider your daily activities and the importance of having crisp, stable vision in your life. If blurry or fluctuating vision has ever interfered with your ability to enjoy life fully, then the investment in scleral lenses may be well worth it. Our eye doctors are happy to discuss financing options and provide clear explanations of the benefits, so you can make an informed decision based on your lifestyle and needs.

Kevin W

My first eye exam in fifteen years. I am so thankful that I found Insight Vision Center. Dr. Lam and staff made me feel like a welcome guest. My eye exam revealed very minor blurriness and Dr. Lam did not pressure me into purchasing eyewear for a condition not necessitating glasses… yet. Maybe next year? I am getting older. They took my VSP insurance. Yay!
