Scleral Contact Lenses

What Are Scleral Contact Lenses?

These unique lenses are much larger than regular contact lenses and work differently to help your eyes feel better and see clearer.

Scleral lenses are bigger than regular contacts. Mini-scleral lenses typically measure 15 to 18 millimeters across, while full scleral lenses range from 18 to 24 millimeters. Standard contact lenses are only 14 to 16 millimeters. They rest on the white part of your eye called the sclera instead of touching your cornea directly. This special design creates a liquid cushion between the lens and your cornea that keeps your eye moist and protected all day long.

These lenses are made from gas permeable materials that let oxygen pass through to keep your eyes healthy. The material is durable and provides sharp, stable vision that stays clear throughout the day without moving around like soft contacts might.

Modern scleral lenses come in different sizes, commonly called mini-scleral or full scleral based on their diameter. Larger designs can improve stability and comfort but must be balanced to allow proper tear flow and oxygen to reach your cornea.

Who Can Benefit From Scleral Lenses

Who Can Benefit From Scleral Lenses

Our ophthalmologists recommend scleral lenses for patients with various eye conditions that make regular contact lens wear difficult or impossible.

People with keratoconus, corneal scarring, or irregular corneas often find great success with scleral lenses. These conditions make the cornea an uneven shape that regular contacts cannot fit properly. By vaulting over the irregular areas, scleral lenses create a smooth optical surface that can restore clear vision and may delay or prevent the need for corneal transplant surgery in some cases.

Patients with severe dry eyes often cannot wear regular contacts because they make symptoms worse. Scleral lenses actually help dry eyes by keeping a reservoir of moisture against your cornea all day. The constant fluid bath under the lens promotes healing and reduces pain, light sensitivity, and irritation significantly.

Patients who have had corneal transplants, LASIK complications, or other eye surgeries sometimes develop irregular corneas. After corneal surgery or trauma, a scleral lens can neutralize irregular vision problems and shield sensitive tissue while the eye recovers or adapts.

If you have very strong prescriptions or high amounts of astigmatism that glasses or regular contacts cannot correct well, scleral lenses might help you. They can provide excellent vision correction for complex prescriptions, though not every patient with high prescriptions will be an ideal candidate.

In severe conditions like limbal stem cell deficiency, exposure problems, or nerve damage to the eye, the constant fluid under a scleral lens can act as a barrier against lid friction and dryness, improving quality of life for patients who have failed other treatments.

Benefits of Scleral Lenses

Benefits of Scleral Lenses

These specialized lenses offer many advantages over regular contacts, especially for people with challenging eye conditions.

Because scleral lenses do not touch your cornea, many people find them more comfortable than regular contacts, especially those with sensitive eyes. The large size means they stay in place better and do not move around when you blink, reducing irritation throughout the day. However, comfort varies by person and depends on proper fit.

The fluid layer between the lens and your cornea creates a perfectly smooth optical surface. The rigid, stable surface often gives you sharper, more stable vision than you might get with glasses or regular contacts, especially if you have corneal irregularities.

The liquid reservoir keeps your cornea hydrated constantly, which is especially helpful for dry eye sufferers. This moisture protection helps your eyes feel comfortable even after wearing the lenses for many hours during busy days.

Scleral lenses protect your cornea from wind, dust, and other irritants in the environment. They also shield your eye from rubbing against your eyelids, which can cause further damage in some conditions.

Scleral lenses tend to stay centered with minimal movement, making them useful for sports or jobs where glasses are not practical. The stable vision and reduced movement improve function in most environments, though very windy conditions or vigorous activity may occasionally cause lens movement.

The Fitting Process

Getting fitted for scleral lenses requires several visits and careful measurements to ensure the perfect fit for your unique eyes.

Our eye doctors will examine your eyes thoroughly and discuss your vision problems and goals. The visit includes a full eye health check, vision testing, and detailed measurements of your cornea and eye surface to determine if scleral lenses are right for you.

During the fitting appointment, we will try different trial lenses on your eyes to find the best fit. Trial lenses of specific sizes are applied and checked to make sure the lens vaults properly over your cornea and lands correctly on the white part of your eye.

Once we find the right basic fit, we customize your lenses for your specific needs. We may adjust the depth, landing zone shape, lens size, and other features to optimize comfort and vision. High-oxygen materials and special coatings may be selected to improve oxygen flow and lens wetting.

Once we find lenses that fit well, we will test your vision and make any needed prescription adjustments. We want to make sure you get the clearest possible vision from your new lenses before we order your final pair.

You will receive step-by-step instruction on insertion, removal, cleaning, and care, and practice under supervision until you feel confident and safe. We start with shorter wear times and gradually increase as your eyes adjust.

After you receive your custom lenses, we will schedule follow-up visits to make sure everything is working well. Regular visits check lens fit, eye health, and vision to make any needed adjustments and support long-term success.

Learning to Use Scleral Lenses

Learning to Use Scleral Lenses

Our team will teach you everything you need to know about inserting, removing, and caring for your new lenses safely.

Learning to put in scleral lenses takes practice, but most patients master the technique quickly. We will show you how to wash your hands properly, fill the lens with preservative-free sterile saline solution, and place it gently on your eye while keeping your face level to avoid air bubbles.

Taking out scleral lenses requires a special small suction cup tool that we provide. We will teach you the proper technique to break the suction at the edge and lift the lens away safely without damaging them or hurting your eyes.

Most patients can wear scleral lenses for 12 to 16 hours per day comfortably. Most people wear them during the day and remove them nightly for cleaning, which lowers infection risks. We will help you develop a wearing schedule that works with your lifestyle and daily activities.

You should take out your lenses if your eyes become red, painful, or irritated. Always remove them before sleeping, swimming, or showering. If vision becomes hazy during the day from debris in the lens, you can remove, clean, refill with fresh saline, and reinsert.

Daily Care and Maintenance

Daily Care and Maintenance

Proper care keeps your lenses clean, safe, and working well for as long as possible.

Clean your lenses every day with the special cleaning solution our doctors recommend. After removal, gently rub the lens with your clean fingers to remove proteins and debris that build up during wear, then rinse as directed and place in the recommended cleaning solution overnight.

In the morning, rinse any cleaning solution residue before filling the lens bowl with preservative-free saline for insertion. Only use sterile, preservative-free saline specifically made for scleral lenses, never tap water or homemade saline solutions.

Use hydrogen peroxide cleaning systems weekly or as directed by our eye doctors. This deep cleaning removes stubborn deposits and kills bacteria that daily cleaning might miss. Always follow the complete neutralization time before putting lenses back in your eyes.

Store your lenses in fresh cleaning solution in a clean case every night. Replace your lens case every three months to prevent bacterial buildup. Keep backup supplies including saline, cleaning solutions, a case, and a backup removal tool when traveling.

Follow the care system exactly as prescribed and avoid water exposure to your lenses. Never use tap water or unregulated saline products. Ask before using any eye drops with lenses in place, and contact our office immediately if you experience redness, pain, discharge, or sudden vision changes.

What to Expect

What to Expect

Understanding the timeline and adjustment period helps you have realistic expectations about your scleral lens experience.

Most patients need one to two weeks to fully adjust to wearing scleral lenses. Your eyes may feel the lenses at first, but this sensation usually goes away as you get used to them. A short adaptation period is normal, but proper fit and technique are key to long-term comfort.

Many patients notice dramatically better vision right away with scleral lenses. Your vision may be clearer and more stable than with glasses or previous contact lenses. The consistent focus throughout the day often improves night vision and reduces glare sensitivity as well.

Comfort usually improves each day during the first week of wear. Many patients find scleral lenses more comfortable than regular contacts after the adjustment period because they rest on the less sensitive white part of the eye and bathe the cornea in protective fluid.

With correct care, lenses typically last six months to two years, but replacement depends on scratches, shape changes, or surface issues that affect performance. Some patients may need replacement sooner depending on their individual lens condition and needs. Regular follow-up helps determine the right replacement timing for safety and optimal vision.

Safety and Important Warnings

Safety and Important Warnings

Daily wear with proper care supports safe long-term use, but it is important to recognize warning signs and follow safety guidelines.

Strict hand washing, daily cleaning and disinfection, and nightly removal are essential to reduce infection risk. While scleral lens infections are rare with proper care, poor hygiene can lead to serious eye infections. Close follow-up and meticulous care are important for safety.

Remove lenses and contact our office immediately for pain, light sensitivity, increased redness, discharge, or sudden vision changes, as these may signal inflammation or infection. Do not resume wear until cleared by our eye doctors after evaluation and treatment if needed.

With modern materials and careful fitting, oxygen problems are uncommon during daily wear in healthy eyes. Our designs aim to minimize thickness and allow proper tear flow to keep your corneas healthy and comfortable.

Sleeping in scleral lenses increases infection and swelling risks and should never be done unless specifically prescribed by our doctors for special medical reasons with close monitoring. Daily removal for cleaning is the safest routine for all patients.

Who Makes a Good Candidate

Who Makes a Good Candidate

Candidacy depends on your eye health, vision goals, and ability to handle and care for the lenses safely.

People with keratoconus, post-surgical irregular vision, corneal scars, severe dry eye, or contact lens intolerance often benefit most from scleral lenses. Those needing stable vision correction for significant astigmatism or very different prescriptions between eyes may also be excellent candidates.

When lenses are prescribed to treat eye disease or restore lost function, they may qualify as medically necessary under certain insurance plans, though requirements vary by insurer. Our staff will help you check your benefits and submit claims for coverage.

Successful scleral lens wear requires dedication to proper daily cleaning, regular follow-up visits, and safe handling techniques. Patients who can maintain good hygiene habits and follow care instructions tend to have the best long-term outcomes.

All contact lenses are medical devices and legally require a valid prescription and proper fitting by an eye care professional. Over-the-counter or unregulated lenses increase the risk of serious eye injury and should always be avoided.

Advanced Options Available

Technology continues to expand what scleral lenses can do for complex eyes and special visual needs.

In eyes with complex vision problems beyond standard prescriptions, customized front-surface designs can reduce glare, halos, or shadowed images when measurements and lens stability allow. These options are highly individualized and may require several trials to optimize.

In rare cases, specialized design features may be used to promote tear flow or address swelling in select eyes. These features are customized to balance comfort, oxygen flow, and vision quality based on your specific needs and are not routinely offered.

Special surface coatings can improve wettability and reduce deposits on the lens surface, especially helpful for patients with certain tear chemistry issues. Coating choice is based on your individual comfort and visual needs observed during follow-up visits.

In severe eye surface diseases that do not respond to other treatments, scleral lenses may be paired with medical treatments or specialized wearing schedules under close medical supervision. These protocols are individualized and monitored frequently to maintain safety.

Frequently Asked Questions

Frequently Asked Questions

Many users find them very comfortable because they rest on the less sensitive white part of the eye and keep the cornea bathed in fluid. While there may be a short adjustment period, many patients find them more comfortable than regular contacts once adapted. However, comfort varies by individual and depends on proper fit.

With proper care, scleral lenses typically last six months to two years before needing replacement. Some patients may need replacement sooner depending on their individual eye chemistry, care habits, and normal wear and tear. Our eye doctors will monitor your lenses and let you know when it is time for new ones.

Yes, the fluid reservoir protects and hydrates the cornea throughout the day, reducing pain and light sensitivity in many severe dry eye cases. They are often very helpful after other dry eye treatments have not provided enough relief.

No, you should never sleep in scleral lenses or any contact lenses unless specifically prescribed by our doctors for special medical reasons. Sleeping in lenses greatly increases your risk of serious eye infections and swelling that can threaten your vision.

Use only the cleaning and storage solutions recommended by our eye doctors, and only sterile, preservative-free saline to fill the lens bowl for insertion. Never use tap water, homemade saline, or unregulated products as these can cause serious eye infections.

Many insurance plans cover scleral lenses when they are medically necessary for conditions like keratoconus, severe dry eyes, or post-surgical vision problems. Our staff will help you check your specific benefits and submit claims for coverage. We also offer payment plans to make treatment affordable.

Children as young as eight years old can successfully wear scleral lenses with proper supervision and training, depending on their maturity and manual dexterity. Children with keratoconus or other corneal conditions often do very well with these lenses. Parents need to help with care and insertion until children master the techniques safely.

If your lens cracks, breaks, or becomes damaged, stop wearing it immediately and contact our office. We keep backup lenses in stock for most patients and can often provide a replacement the same day. Never try to repair a damaged lens yourself.

If vision becomes hazy from debris in the lens reservoir, you can remove the lens, clean the front surface if needed, refill with fresh sterile saline, and reinsert to restore clarity. If fogging happens frequently, discuss fit adjustments with our doctors.

They can be very helpful for vision rehabilitation and protection after corneal surgery, but fitting must focus on proper oxygen flow and tear exchange, especially if the inner layer of the cornea is compromised. Close monitoring and careful design choices help ensure safety.

Scleral lenses vault completely over the cornea and land on the white part of the eye with a fluid reservoir underneath, while regular hard contacts rest directly on the cornea and move with each blink. The scleral design often provides more stable vision and comfort for irregular corneas.

During fitting, we try different trial lenses to find the best size and shape for your eyes. We use special equipment to check that the lens clears your cornea properly and lands correctly on the white part of your eye. The process may take several visits to achieve the perfect fit.

Yes, you can wear makeup with scleral lenses. Put your lenses in before applying makeup and remove them before taking makeup off. Use oil-free makeup remover and avoid getting makeup on your lenses or in your eyes.

Avoid swimming, showering, or any water activities while wearing your lenses. Remove them before sleeping or napping. Most other activities including sports are fine, but discuss specific concerns with your eye doctor.

Initially, you will need more frequent visits to ensure proper fit and comfort. Once stable, most patients need check-ups every six months to monitor lens condition, eye health, and vision. Some patients may need more frequent visits based on their individual needs.

If you feel debris or irritation under your lens, remove it immediately. Clean the lens if needed, rinse with fresh preservative-free saline, and reinsert. If irritation continues, contact our office before wearing the lens again.
