Scleral lenses are a specialized type of contact lens designed for patients who have unique needs that are not solved with traditional contact lenses. Their unique design provides benefits that other lenses do not, such as:

Custom Mapping: Tailored design for optimal comfort and clear vision.
Corneal Vaulting: Sits over the cornea to reduce irritation and provide a new optical surface.
Liquid Cushion: Maintains hydration, protects against dryness, improves visual clarity.
Larger Size: Offers superior stability, better peripheral vision, increased comfort, protection from the elements, and extended wear comfort.

This innovative design makes scleral lenses especially useful for individuals with irregular corneas (like keratoconus) or severe dry eye, where conventional lenses often fail to provide comfort or clarity.

Unique Advantages of Scleral Lenses

Custom-Mapped Design

Scleral lenses are custom-made to match the precise shape of your eye. Using advanced imaging and mapping, the lens is crafted to the unique contours of your cornea and sclera. This tailored fit ensures optimal lens alignment, resulting in maximum comfort and superior clarity of vision for the wearer. In practice, this means fewer issues with lenses shifting or causing pressure points, since the lens conforms closely to your eye’s anatomy. The precise customization not only enhances comfort but also helps deliver sharper vision than one-size-fits-all contacts, particularly important for complex prescriptions or corneal irregularities.

Vaults Over the Cornea

Unlike regular contacts that sit on the cornea, scleral lenses are designed to vault over the cornea entirely and rest on the less sensitive sclera. Because the lens doesn’t touch the corneal surface, it avoids aggravating any irregular or sensitive areas on the cornea. This greatly reduces irritation and light sensitivity that some people experience with standard lenses. By minimizing direct contact with the cornea, scleral lenses provide enhanced comfort even for those with conditions like keratoconus or corneal scarring. The vaulting design also creates a consistent optical surface, contributing to more stable and clear vision since the uneven corneal shape is effectively bypassed.

Liquid-Filled Cushion

One of the hallmark benefits of scleral lenses is the liquid reservoir that sits between the back of the lens and the cornea. Before inserting a scleral lens, it is filled with sterile saline solution. When the lens is on the eye, this fluid layer forms a continuous cushion of moisture over the cornea. The result is that the eye’s surface stays hydrated throughout the day, which protects against dryness and discomfort. This is especially advantageous for individuals with severe dry eye syndrome, patients with conditions such as sjorgens and lupus, and those with damaged corneas. Additionally, the fluid cushion can aid in healing or protecting a damaged cornea by providing constant lubrication and a smooth refractive surface.

Larger Size and Greater Stability

Scleral lenses are noticeably larger than standard soft or gas-permeable contacts, often spanning 15 to 20+ millimeters in diameter (versus ~9-14 mm for regular lenses). This larger size serves a purpose: it anchors the lens more securely on the eye. The broad diameter distributes pressure evenly and prevents the lens from moving around or popping out easily. Thanks to this design, scleral lenses offer greater stability, remaining centered over the cornea even during blinking or quick eye movements. For patients with irregular corneas, this stability helps maintain a consistently clear optical pathway, reducing visual distortions. Moreover, the combination of stability and the continuous hydration from the fluid reservoir means many users can comfortably wear scleral lenses for extended periods. Scleral lenses are designed for longer wear times, with many patients finding they can wear them all day without discomfort. The enhanced stability and moisture also make them ideal for athletes, first responders, pilots and others that want to maintain an active lifestyle or need reliable vision correction throughout their workday.

Comparing Scleral Lenses to Other Contact Lens Options

Comfort and Fit

Scleral lenses provide an improved level of comfort because they bypass the sensitive cornea. Unlike many gas‐permeable lenses that rest directly on the cornea, scleral lenses rest on the sclera, reducing friction and minimizing discomfort. Soft lenses, while comfortable upon insertion, may not always provide the optimal correction for patients with severe corneal irregularity or dry eye issues. This is why many patients find that scleral lenses offer a refreshing alternative when traditional lenses prove too abrasive or unstable.

Protection Against Environmental Irritants

The design of scleral lenses helps in shielding the cornea from dust, smoke, and other environmental irritants. Because they create a seal over the eye and provide a protective layer of moisture, they serve as a barrier against debris that might otherwise irritate the eye. This feature is especially beneficial for individuals who work in environments with high levels of airborne particulate matter or who experience irritation from everyday exposure to dust and pollutants.

Visual Stability and Clarity

One of the standout features of scleral lenses is their ability to deliver consistently clear vision. Because they are designed to maintain a stable fluid reservoir between the lens and the cornea, they help to smooth out irregularities and offer steady visual acuity. For patients with conditions like keratoconus or high astigmatism, this feature can mean the difference between a frustrating experience with moving lenses and a stable, reliable correction throughout the day. In contrast, standard rigid gas‐permeable lenses may shift with every blink, potentially causing blurred vision or discomfort.

Comparing Scleral Lenses and Corneal Gas Permeable Lenses

Since many patients of Suitability for Special Conditions
Scleral lenses are particularly advantageous for patients with specific eye conditions such as:

Keratoconus: A condition that causes the cornea to thin and become irregularly shaped. The vaulting design of scleral lenses helps create a smooth optical surface, improving vision noticeably.
Irregular Corneas: Whether due to trauma, surgery, or conditions such as corneal dystrophy, patients with irregular corneas often benefit significantly from the custom‐fit of scleral lenses.
Dry Eye Syndrome: For individuals who struggle with chronic dryness, the tear reservoir provided by scleral lenses not only hydrates the eyes but also ensures that vision remains clear and comfortable over a long period of wear.
High Astigmatism: The inherent stability of scleral lenses means that they can correct residual astigmatism more effectively compared to other types of lenses that shift on the eye.

In these cases, the tailored design of scleral lenses often makes them a superior choice, offering both visual clarity and comfort that may not be achievable with regular contacts.

A Breakdown of the Main Differences

Majority of patients wonder whether scleral lenses are a superior option compared to traditional gas‐permeable (GP) lenses, let’s break down the main differences:

Placement

Scleral lenses vault above the cornea, landing on the sclera, whereas GP lenses sit directly on the corneal surface. This difference is key for patients with corneal sensitivities or irregularities, as scleral lenses reduce direct contact with the sensitive corneal tissue.

Vision Stability

Because GP lenses can shift with each blink, patients might experience fluctuating vision. Scleral lenses, due to their robust design and secure seating, provide a consistently centered lens that improves visual stability throughout the day.

Protection

Scleral lenses offer an extra barrier against dust, smoke, and other environmental irritants. This is particularly valuable for those who suffer from dry eye or have sensitive ocular surfaces, as it helps reduce irritation and discomfort.

Adaptation Period

While both types of lenses might require an adjustment period, scleral lenses often need a bit more time initially due to their larger size. However, patients who overcome this early phase frequently report significantly enhanced comfort and stability compared to GP lenses.

When patients compare their experiences with GP lenses versus scleral lenses, many praise the latter for being as comfortable as soft lenses yet superior in vision stability and the protection they offer the corneal surface. Clearly, for patients with specific eye conditions, these advantages can tip the scale in favor of scleral lenses.

Ideal Candidates for Scleral Lenses

Individuals with Corneal Irregularities

Patients who have conditions like keratoconus, pellucid marginal degeneration, or post‐surgical corneal changes fit well with scleral lenses because these lenses provide a uniform refractive surface.

People Suffering from Severe Dry Eye

Those who experience significant discomfort due to dryness often find relief with a continuous layer of lubrication that scleral lenses maintain during wear.

Patients with High Astigmatism

The stability of scleral lenses can better manage residual astigmatism, reducing the need for additional vision correction like prescription eyeglasses worn over lens wear.

Individuals with Ocular Surface Disease

For cases where the cornea might be sensitive or irregular due to disease, the protective aspect of scleral lenses can be quite beneficial.

Active Lifestyles

Because of their secure fit and resistance to dislodgement, scleral lenses are excellent for those who regularly participate in sports or physically demanding activities.

The Role of Our Contact Lens Specialists in Your Decision

Final Verdict: Are Scleral Lens The Best Contact Lens

The answer is clearly yes….for certain people. Without a doubt scleral lenses are the best lens for those that require the unique benefits that it provides.

However for certain patients, other lenses may be preferable. For patients that prioritize convenience, and have no issues with daily disposable lenses, they may find the benefit of disposables make them a better choice. For kids with myopia, OrthoK lenses or multifocal lenses for myopia management are better, as they provide the added benefit of slowing myopia progression.

It also depends on how the question is phrased, as in certain areas they are the best without a doubt. Scleral lenses are the best in comfort, stability, clarity, and are an amazing lens for many patients especially patients with various conditions from keratoconus to dry eye.

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!

Scott H.

Dr. Lam and staff are amazing. Every phone call or interaction is friendly. You can feel the smiles and joy over whatever mode of communication you are interacting with them. Dr. Lam is very knowledgeable and helps you to better understand everything that is going on with your eyes. She made me aware of potential problems I may have with my eyes and walked me through every step of the process. She helped me understand the various factors that could be causing my vision to be a little impaired and followed up with me as I had to see an ophthalmologist. Great team, great office.
