Scleral lenses are changing how patients with complex vision needs see the world. Traditional contacts often fall short for people with irregular corneas, post-surgical vision issues, or severe dry eye. These larger, custom-designed lenses vault over the entire cornea to deliver stable vision, lasting comfort, and continuous hydration.
Scleral lenses are rigid gas permeable contacts that arch completely over the cornea and rest on the sclera, the white part of the eye. A fluid-filled space beneath the lens creates a continuous layer of moisture. This reservoir shields the cornea from the environment and smooths out surface irregularities.
Unlike standard contacts, scleral lenses do not touch the cornea at all. We custom-make them using detailed measurements of each eye. The larger diameter allows the lens to rest gently on the less sensitive scleral tissue, which makes them more comfortable than smaller rigid lenses.
The fluid layer beneath the lens acts as a new optical surface. This smooths out corneal irregularities caused by conditions like keratoconus or previous eye surgery. The result is crisp, stable vision that glasses and soft contacts often cannot match.
Because scleral lenses rest on the sclera rather than the cornea, they spread their weight over a larger, less sensitive area. Many patients find them more comfortable than standard rigid lenses, even during long wear.
The saline reservoir beneath the lens keeps the cornea moist throughout the day. This feature is especially helpful for patients with dry eye or conditions that reduce tear production.
Scleral lenses maintain a smooth optical surface that does not shift or rotate on the eye. This provides sharp, consistent vision for people with irregular corneas or high astigmatism.
The lens forms a physical barrier that shields the cornea from dust, allergens, wind, and other irritants. This can reduce discomfort for patients with allergies or those who work in challenging environments.
Scleral lenses stay in place during physical activity. Athletes and active patients benefit from vision that remains clear and stable, even during rapid movement or contact sports.
People with keratoconus, pellucid marginal degeneration, or other conditions that change corneal shape often see dramatically better with scleral lenses. The fluid layer creates a smooth optical surface over the irregular cornea.
LASIK, PRK, and radial keratotomy can sometimes leave the cornea with lasting irregularities. Scleral lenses restore a uniform front surface for dependable clarity when glasses or soft contacts no longer work well.
Patients with chronic dry eye, including those with autoimmune conditions, often struggle with standard contact lenses. The constant moisture environment of a scleral lens can provide relief and allow comfortable lens wear.
When glasses, soft contacts, or smaller rigid lenses cannot meet your visual or comfort needs, scleral lenses often succeed. We design them for the most challenging fitting situations.
Keratoconus causes the cornea to thin and bulge into a cone shape, leading to blur and distortion. Scleral lenses vault over the irregular cornea, providing stability and improved vision without touching the cone.
Patients with very high astigmatism often find glasses or soft toric contacts insufficient. Scleral lenses provide consistently sharp vision without the rotation issues that can blur vision in standard toric lenses.
LASIK, PRK, and radial keratotomy can cause lasting corneal irregularities in some patients. Scleral lenses mask these irregularities and restore clear, stable vision. They are often the best option when other corrections fail.
After a corneal transplant, sutures and irregular healing can make regular lenses unwearable. Scleral lenses protect the graft while providing stable vision during the healing process and beyond.
Conditions like Fuchs' dystrophy cause swelling and haze in the cornea. Special scleral lens designs with drainage channels can help manage excess fluid while maintaining clear vision.
During healing from burns or chemical exposure, scleral lenses form a protective shield. They keep the corneal surface moist and can reduce discomfort during recovery.
Conditions like lagophthalmos, ptosis, and Bell's palsy can prevent the eyelids from closing fully. Scleral lenses maintain hydration and protect the cornea when incomplete blinking leaves it exposed.
Patients with Sjogren's syndrome, Stevens-Johnson syndrome, and graft versus host disease often have severely compromised tear production. Scleral lenses create a constant moisture environment that can restore comfort and protect the ocular surface.
Scleral lenses shield the cornea from allergens like pollen and dust. They also protect against harsh environmental conditions such as wind, smoke, and air conditioning.
Athletes face challenges like lens displacement, dryness, and blurred vision during rapid movement. Scleral lenses provide locked-in, fog-free clarity that withstands the demands of competitive sports.
Traditional rigid gas permeable lenses sit directly on the cornea, while scleral lenses vault completely over it. Sclerals spread their weight over the sclera, making them more comfortable. They also maintain hydration, while standard RGPs can worsen dryness.
Soft lenses conform to the shape of the cornea, which limits their ability to correct irregular astigmatism. Scleral lenses create a new optical surface that does not depend on corneal shape. They also stay more secure and resist drying during long wear.
Scleral lenses often outperform other options for keratoconus, high astigmatism, post-surgical irregularity, and severe dry eye. Patients who have struggled with other lenses frequently find success with sclerals.
The fitting process starts with precise measurements of the cornea and sclera. Advanced corneal topography maps the eye's surface in detail. Wavefront analysis identifies optical irregularities that the lens must correct.
Every scleral lens is designed specifically for your eyes. The measurements guide the selection of lens diameter, curvature, and optical power. At Insight Vision Center Optometry, our optometrists like Dr. Nathan Schramm, OD, FSLS, FBCLA and Dr. Thanh Mai, OD, FSLS, FIAOMC use advanced imaging tools including the Tomey WaveDyn Aberrometer and AS-OCT to ensure precise fits.
After the initial fitting, you will return for follow-up visits so we can assess comfort and vision. We make adjustments as needed to optimize the fit. This personalized approach sets scleral lenses apart from mass-produced options.
Scleral lenses require careful cleaning each day. You will learn to use approved solutions to remove debris and protein deposits. Proper cleaning extends lens life and reduces the risk of eye irritation.
Before insertion, you must fill the scleral lenses with preservative-free saline. We teach you specific techniques to insert the lens without trapping air bubbles beneath it. Consistent technique ensures comfort throughout the day.
You should store lenses in fresh solution overnight. We provide detailed guidance on lens case hygiene and replacement schedules. Following these steps helps maintain healthy eyes and clear lenses.
Most patients adjust to scleral lenses within one to two weeks. The lenses may feel unusual at first, but comfort typically improves quickly as your eyes adapt. Patients with prior contact lens experience often adapt faster.
Many patients wear scleral lenses comfortably for 12 to 16 hours per day. Your optometrist will recommend a wearing schedule based on your individual eye health and needs. Some patients may need to remove and refill lenses during very long days.
With proper care, scleral lenses can provide years of clear vision and comfort. Regular follow-up visits help us catch any changes early and keep the fit optimized. Many patients report that scleral lenses have transformed their quality of life.
Most patients learn to handle scleral lenses within a few practice sessions. Special insertion and removal tools are available to make the process easier. Your optometrist will train you until you feel confident with the technique.
With proper care, scleral lenses typically last one to three years. Replacement timing depends on the lens material, how well you maintain the lenses, and any changes in your prescription or eye health.
Scleral lenses are generally not approved for overnight wear. Sleeping in them can reduce oxygen flow to the cornea and increase the risk of complications. Always remove your lenses before sleep unless your optometrist specifically advises otherwise.
Many patients with dry eye find significant relief with scleral lenses. The fluid reservoir keeps the cornea hydrated throughout the day. However, results vary depending on the underlying cause and severity of dry eye. If you think you might have dry eye, try our dry eye quiz to assess your symptoms.
Yes. Scleral lenses are often prescribed for patients with vision problems after LASIK or other refractive surgeries. They can correct irregularities that developed after surgery and restore clear vision.
After the initial fitting period, most patients return once or twice per year for routine follow-up. More frequent visits may be needed if you have underlying eye conditions or if we need to adjust the fit.
