Do Scleral Lenses Treat Dry Eye?
What Are Scleral Lenses?
Scleral lenses are large-diameter, rigid gas permeable contact lenses that vault over the cornea and rest on the white part of the eye, the sclera. They are designed to create a protective fluid-filled chamber over the cornea, which helps shield the eye from environmental irritants and maintains continuous hydration.
Scleral lenses rest on the white part of the eye, called the sclera, instead of sitting directly on the sensitive cornea. This unique design allows them to vault over the cornea, forming a small reservoir filled with preservative-free saline solution. The lens essentially creates a mini aquarium for your eye, keeping it constantly bathed in moisture. Brands like Boston XO and Zenlens are common examples that our eye doctors might recommend based on individual needs.
Unlike soft daily contacts that sit right on the cornea and can dry out quickly, scleral lenses are bigger and made from rigid, gas-permeable materials that allow oxygen to pass through. Their larger size and rigid structure help minimize lens movement and reduce drying out during the day, making them much less likely to cause discomfort even in challenging environments like air-conditioned offices.
Modern scleral lenses use advanced materials that let plenty of oxygen reach the eye while maintaining their shape and comfort. The lens curves are precisely calculated using detailed eye measurements to ensure a proper fit and fluid circulation. This scientific approach means each lens is custom-made for the individual patient's eye shape and dry eye needs, resulting in a medical device that can transform daily comfort.
Scleral lenses have been around since the 1800s, with early versions made of glass that were heavy and uncomfortable. Today’s lenses use advanced, high-oxygen permeable plastics and computerized molding technology, allowing for highly customized fits that make them lightweight and breathable. Modern advances have made them a leading option for managing various eye issues, including severe dry eye.
Recent innovations include lens materials that maximize oxygen flow to the cornea, hydrophilic coatings that enhance wettability, and surface treatments that reduce protein deposits and fogging. These features help increase comfort, extend wear time, and improve visual outcomes for patients with challenging dry eye conditions.
Because each eye is unique, scleral lenses require a careful, personalized fitting process. Eye doctors use advanced imaging and impression techniques to map the curvature of the eye, ensuring the lens fits securely and comfortably. This customization is key to achieving optimal comfort, hydration, and vision correction for dry eye patients.
How Do Scleral Lenses Help with Dry Eye?
Scleral lenses work like a protective shield for the eyes, trapping moisture, blocking environmental irritants, and providing symptomatic relief. They are most effective as part of a comprehensive dry eye management plan, which may also include other treatments.
When filled with preservative-free saline solution, scleral lenses create a constant layer of moisture over the cornea that never dries out during normal wear. This helps prevent the rapid evaporation of natural tears, which is one of the main problems in dry eye disease. Patients often notice less burning, stinging, or itching after wearing them for just a few hours, providing relief that eye drops alone cannot match.
These lenses act as a physical barrier against wind, dust, pollen, and dry air from reaching the eye's surface directly, reducing irritation from common environmental triggers. For people who live in dry climates or work in air-conditioned offices, this protection can make a dramatic difference. Research shows that over 85% of patients with severe dry eye report substantial improvement in symptoms and overall comfort.
Dry eye often happens when the tear film breaks down too quickly, but scleral lenses help stabilize it by maintaining a steady, healthy fluid environment around the cornea. This leads to clearer, more stable vision and reduces the blurred sight that dry eye patients often experience, especially when reading or using computers.
While artificial tears like Refresh or Systane provide quick but temporary relief, scleral lenses offer continuous hydration for up to 16 hours without frequent reapplication. They can be more effective than punctal plugs for many patients because they address both moisture retention and environmental protection, often reducing reliance on topical medications.
In addition to relieving dryness, scleral lenses can improve visual clarity for patients with irregular corneas or scarring by creating a perfectly smooth optical surface over the eye. This dual benefit, improved comfort and sharper vision, makes them a valuable tool for many people with complex eye conditions.
By shielding the cornea from mechanical friction from the eyelids and maintaining constant hydration, scleral lenses may help reduce eye surface inflammation associated with chronic dry eye. This can lead to a decrease in redness, discomfort, and the sensation of foreign bodies in the eye.
Who Can Benefit from Scleral Lenses for Dry Eye?
Not everyone with dry eye is a good candidate for scleral lenses, but many people find them life-changing after trying other treatment options. Eye doctors carefully assess factors like eye shape, tear production, and severity of symptoms to determine if they are the right fit.
Those who have tried over-the-counter drops, prescription medications, and lifestyle changes but still experience daily discomfort often benefit the most. People with Sjögren's syndrome, graft-versus-host disease, or other autoimmune conditions that cause severe dry eye frequently find significant relief.
Conditions like keratoconus, post-surgical irregularities, or corneal scarring make regular contacts uncomfortable and often worsen dry eye symptoms. Scleral lenses smooth over these irregularities while simultaneously hydrating the eye, providing dual benefits for both vision correction and moisture retention.
Individuals who work in dusty environments, spend time outdoors, or participate in sports may find scleral lenses protect against irritants much better than glasses or regular contacts. They stay securely in place even during physical movement and provide consistent moisture protection.
Incomplete eyelid closure (lagophthalmos), which can occur after Bell’s palsy, stroke, or trauma, can cause severe corneal exposure and dryness. Scleral lenses protect the exposed cornea, maintaining hydration and reducing the risk of corneal damage.
People with very small eyes, active eye infections, certain autoimmune conditions affecting the sclera, or an inability to handle and care for the lenses may not be ideal candidates. Patients who have difficulty with fine motor skills might need alternative treatments.
Getting Fitted and Using Scleral Lenses
Fitting scleral lenses is a precise process that requires specialized training and equipment to ensure they match each eye's unique shape and needs. Proper insertion, removal, and daily care are essential skills that patients learn to get the maximum benefit for dry eye relief.
Eye doctors use advanced measuring tools and corneal mapping to create custom lenses that fit your specific eye shape. This detailed process may take several visits over a few weeks to get the fit, comfort, and vision just right. Patients should expect some adjustments, but the result is typically long-lasting comfort and significant symptom improvement.
Inserting scleral lenses involves filling them with sterile saline solution and placing them gently on the eye using a proper technique to avoid air bubbles. Removal uses a small plunger tool designed to safely lift the lens off without touching the eye directly. With guided practice, this process becomes quick and routine.
Proper cleaning and storage keep lenses working effectively and prevent serious eye infections. Daily cleaning with approved solutions, such as Clear Care or Boston Simplus, removes protein deposits, bacteria, and debris that can build up and cause irritation.
- Clean lenses thoroughly after each use with approved cleaning solutions.
- Rinse with sterile saline before insertion to remove any cleaning residue.
- Never use tap water, saliva, or homemade solutions that can cause dangerous infections.
- Replace lenses as recommended, typically every one to two years or sooner if damaged.
- Attend all scheduled follow-up visits to monitor eye health and lens fit.
Some new users experience air bubbles, midday fogging, or slight discomfort during the first few weeks, but adjusting the saline fill amount and insertion technique usually resolves these issues. If problems persist, follow-up visits allow the eye doctor to fine-tune the lens fit or make other adjustments.
Potential Drawbacks and Important Considerations
While scleral lenses offer excellent relief for many dry eye patients, it is important to understand the challenges and costs involved. Discussing these factors openly with your eye care professional helps set realistic expectations.
Scleral lenses can cost between $1,500 and $3,000 per pair, with additional expenses for professional fitting, follow-up visits, and care supplies. Many insurance plans cover part of the cost when deemed medically necessary for severe dry eye, but patients should verify coverage details before beginning treatment.
Getting comfortable with handling larger lenses and maintaining proper hygiene takes time and patience, especially for people new to contact lenses. The daily routine requires dedication, but most patients find that the significant improvement in comfort and quality of life makes the effort worthwhile.
Not following proper cleaning protocols or wearing lenses longer than recommended can lead to serious eye infections that may worsen dry eye symptoms or cause permanent damage. Strict adherence to care instructions is essential for safe, long-term use.
If scleral lenses are not suitable or do not provide enough relief, other advanced treatments like autologous serum tears, intense pulsed light (IPL) therapy, or amniotic membrane therapy might be helpful. Each person's condition is unique, so working with your eye doctor to explore all options is important.
