Scleral Lens Fittings
What Are Scleral Lenses
Scleral lenses are large contact lenses that rest on the clear tissue covering the white part of your eye. Unlike regular contacts that sit on your cornea, these lenses create a protective dome over your entire cornea.
These lenses work by arching over your cornea, resting on the sclera (the white part of your eye) while maintaining a fluid-filled space between the lens and the cornea. This design helps keep your eye moist and protected while allowing oxygen to flow through the lens material to keep your eyes healthy.
Scleral lenses typically range from 14 to 24 millimeters in diameter, with 'corneo-scleral' lenses measuring between 14 and 18 millimeters and providing a smaller option compared to the larger 'true scleral' lenses. Their unique bowl shape creates space above your cornea while the edges rest comfortably on your eye. This larger size makes them more stable and less likely to move around.
Made from rigid gas-permeable materials, scleral lenses allow oxygen to pass through to your cornea. This breathable material helps maintain healthy eye function while providing the structure needed for clear vision. The rigid design also helps the lens maintain its shape for consistent vision correction throughout the day.
Each scleral lens is custom-made to fit the unique shape of your cornea, sclera, and overall eye anatomy, ensuring optimal vision and comfort.
Who Benefits from Scleral Lenses
These special lenses help patients with various eye conditions that make regular contacts uncomfortable or ineffective. Our eye doctors carefully evaluate each patient to determine if scleral lenses are the right solution.
Patients with keratoconus have corneas that bulge outward in a cone shape. Regular contacts cannot fit properly on this irregular surface, causing discomfort and poor vision. Scleral lenses vault over the irregular cornea, creating a smooth surface that provides clear, stable vision all day long.
People with moderate to severe dry eye syndrome often cannot wear regular contacts comfortably. Scleral lenses trap tears between the lens and your eye, creating a constant moisture reservoir. This design keeps your eyes hydrated throughout the day and reduces dry eye symptoms significantly. For mild to moderate dry eye, smaller specialty lenses may also be an option.
Patients with corneal scars, injuries, or surgical complications may have irregular corneal surfaces. These irregularities make it difficult to achieve clear vision with glasses or regular contacts. Scleral lenses create a new, smooth front surface for your eye, dramatically improving visual clarity and reducing glare and halos.
After corneal transplants or other eye surgeries, once healing is complete, the cornea may have an irregular shape that makes regular contacts uncomfortable. Scleral lenses can provide comfortable vision correction without touching the sensitive corneal tissue. They also protect the cornea from irritation and environmental factors that could cause problems.
Patients with severe astigmatism may not achieve clear vision with regular soft contacts or glasses. The rigid design of scleral lenses maintains its shape on the eye, providing stable correction for high amounts of astigmatism throughout the day without the lens rotating or moving.
Some patients have multiple vision issues that are difficult to correct with standard methods. Scleral lenses can address both optical and comfort needs at the same time. They work well for patients who need both vision correction and eye surface protection in one solution.
Scleral lenses are not suitable for everyone. Patients with severe corneal swelling, active eye infections, or extreme ocular surface disease may not be good candidates. Your eye doctor will carefully evaluate your specific condition to determine if these lenses are appropriate for you.
The Fitting Process
Getting fitted for scleral lenses requires expertise and patience. Our eye doctors use advanced technology and careful assessment to ensure your lenses fit perfectly and provide optimal vision.
Your fitting begins with a comprehensive eye exam and detailed corneal mapping. We use special equipment to measure the exact shape and size of your cornea and the white part of your eye. This information helps us select the best starting lens design for your unique eye shape and vision needs.
We place trial lenses on your eyes to evaluate the fit and comfort. Using blue light and special dye, we check that the lens vaults properly over your cornea without touching it. The lens should have adequate clearance over your entire cornea while resting comfortably on the tissue covering the white part of your eye.
Once we achieve the proper fit, we determine your prescription through the scleral lens. This process ensures you get the clearest possible vision with your new lenses. We may need to try several different lens designs to find the perfect combination of fit and vision quality.
Learning to handle scleral lenses takes practice because of their larger size. Our team teaches you the proper technique for inserting and removing your lenses safely. We provide hands-on training until you feel confident managing your lenses independently at home. Some patients may need multiple training sessions or take-home materials to master the technique.
After you receive your custom lenses, we schedule regular follow-up appointments. These visits allow us to monitor your eye health, assess lens performance, and make any necessary adjustments. Proper follow-up care ensures long-term success with your scleral lenses and helps prevent complications.
Scleral lenses settle on your eye over the first few hours of wear. We time our assessments to account for this settling and may need to see you multiple times. This careful monitoring ensures your lenses maintain proper clearance and alignment as they settle into position. Too much settling can cause problems, so we watch this closely.
Benefits of Scleral Lenses
Patients who wear scleral lenses often experience dramatic improvements in both vision quality and comfort. These benefits make scleral lenses an excellent choice for many challenging eye conditions.
Because scleral lenses do not touch your cornea, they eliminate the discomfort often associated with regular contacts. The larger size also makes them more stable, reducing movement and irritation during blinking. Most patients find them comfortable to wear for many hours each day once they adjust to the feeling.
Scleral lenses provide sharper, more stable vision than glasses or regular contacts for many eye conditions. They correct irregular vision problems that other options cannot address effectively. The fluid reservoir also maintains consistent clear vision throughout the day without the fluctuation you might experience with other options.
These lenses protect your cornea from environmental irritants, wind, and debris throughout the day. The design also protects against eyelid friction, which can be helpful for patients with certain eye conditions. This protective effect can help prevent further damage to sensitive corneal tissue.
The larger size of scleral lenses makes them less likely to move around or fall out compared to smaller contacts. This stability reduces the risk of contamination and eye infections significantly. The gas-permeable material also resists protein buildup better than soft contact materials.
With proper care, scleral lenses typically last one to three years before needing replacement. Their durable material resists wear and tear better than soft contacts. This longevity makes them a cost-effective option despite the higher initial investment required.
Care and Maintenance
Proper care extends the life of your scleral lenses and keeps your eyes healthy. Our team provides detailed instructions for cleaning and storing your lenses safely at home.
Clean your lenses every day with the recommended cleaning solutions. Rub the lenses gently to remove protein deposits and debris that can build up during wear. Always use fresh cleaning solution and never reuse cleaning solution from previous days. Some doctors recommend hydrogen peroxide-based solutions for thorough disinfection.
Store your lenses in fresh conditioning solution when not wearing them. Use the storage case recommended by our office and replace it regularly as directed. Never store lenses in water or saline solution, as these can damage the lens material over time or cause serious eye infections.
Always wash your hands thoroughly before handling your lenses with soap and water. Fill the lens bowl completely with preservative-free saline before insertion to avoid air bubbles. Check the lens for damage or debris before placing it on your eye each time. Avoid touching the inside bowl of the lens to prevent contamination.
Only use non-preserved sterile saline to fill the lens bowl before insertion. Never use tap water, multipurpose solutions, or preserved eye drops in the lens bowl. These can cause serious eye infections or irritation that may damage your eyes permanently.
Follow the replacement schedule we provide based on your specific lenses and wearing patterns. Most scleral lenses need replacement every one to three years depending on the material and your individual needs. Never wear lenses beyond their recommended replacement date for safety reasons. Advances in materials may allow some lenses to last longer with proper care.
What to Expect
Understanding the adjustment period and what to expect helps ensure success with your new scleral lenses. Most patients adapt well with proper guidance and realistic expectations.
Most patients need time to adjust to the feeling of wearing larger lenses. You may notice increased awareness of the lens initially, but this sensation typically decreases within a few days to weeks. Start with shorter wearing times and gradually increase as comfort improves over time.
Many patients notice immediate improvement in vision clarity once the lenses are properly fitted. However, your brain may need time to adapt to the new visual input, especially if you have had poor vision for a long time. Maximum visual benefit often develops over several weeks of consistent wear.
Comfort typically improves as you become accustomed to inserting and wearing the lenses. Most patients develop confidence with handling within the first few weeks of wear. Our team is available to help with any difficulties during this adjustment period with additional training if needed.
You may need to make minor adjustments to your daily routine, such as allowing extra time for lens insertion and removal. Most activities including sports and exercise are possible with scleral lenses. We can provide specific guidance based on your lifestyle and activities.
Learn to recognize when you should stop wearing your lenses and contact our office. Remove lenses immediately if you experience pain, significant redness, light sensitivity, or sudden vision changes. Other warning signs include persistent discomfort, ghosting, halos, or any unusual symptoms. Early evaluation helps prevent complications and protects your eye health.
While rare, complications can include corneal swelling from lack of oxygen, lens binding to the eye, tissue irritation, or blood vessel growth. Regular follow-up appointments help us monitor for these issues and address them quickly if they occur. Most complications can be prevented with proper fit and care.
Treatment Alternatives
While scleral lenses are excellent for many conditions, they are not the only option available. Understanding alternatives helps ensure you receive the best treatment for your specific needs.
Hybrid lenses have a rigid center with a soft outer edge, combining clear vision with comfort. These may be suitable for some patients with mild to moderate irregular corneas who do not need the full coverage of a scleral lens.
This involves wearing a soft contact lens with a rigid lens on top. The soft lens provides cushioning while the rigid lens corrects vision. This system works for some patients who cannot tolerate rigid lenses directly on their cornea.
Custom soft lenses designed for irregular corneas may help some patients with milder conditions. These are often more comfortable initially but may not provide the same level of vision correction as rigid options.
Depending on your condition, surgical treatments like corneal cross-linking, corneal transplants, or other procedures may be appropriate. Your eye doctor can discuss whether surgery might be beneficial before or instead of specialty contact lenses.
Complex cases may require referral to a corneal specialist or contact lens subspecialist. These experts have additional training in managing difficult-to-fit eyes and access to the most advanced lens designs and fitting techniques.
Cost and Insurance
Understanding the financial aspects of scleral lens treatment helps you plan for this investment in your vision and eye health.
Many insurance plans provide coverage for scleral lenses when they are medically necessary for conditions like keratoconus or corneal irregularities. Coverage varies significantly between plans, so verification of benefits is important before starting treatment. Our office staff can help determine your coverage and obtain pre-authorization when required.
The cost of scleral lens treatment includes the initial fitting, lens manufacturing, follow-up visits, and ongoing care. While more expensive initially than regular contacts, the longer lifespan and potential to avoid surgery may make them cost-effective over time.
We work with patients to explore payment options for specialty lens fitting. Some patients use health savings accounts or flexible spending accounts to help cover costs. Payment plans may also be available to make treatment more affordable.
Consider the long-term value of improved vision and quality of life when evaluating cost. Many patients find that the ability to see clearly and comfortably is worth the investment, especially when other options have failed to provide adequate results.
Frequently Asked Questions
The initial fitting appointment typically takes two to three hours. This allows time for comprehensive measurements, trial fitting, and training on insertion and removal. You may need several follow-up visits over the first few months to ensure optimal fit and comfort. The entire process from first visit to final lens delivery usually takes four to eight weeks.
Many insurance plans provide coverage for scleral lenses when they are medically necessary for conditions like keratoconus, severe dry eye, or corneal irregularities. Coverage varies significantly between insurance companies and plans. Our office staff can verify your benefits and help determine your coverage before starting the fitting process. Pre-authorization may be required.
No, scleral lenses are designed for daily wear and should be removed before sleeping. Extended wear increases the risk of complications including corneal swelling, infections, and other serious problems. Most patients wear their lenses comfortably for 12 to 16 hours during waking hours.
If your prescription changes, we can often modify your existing lenses rather than replacing them entirely. Minor prescription changes can sometimes be incorporated into the current lens design. Regular eye exams help us monitor any changes and adjust your lenses accordingly. Significant prescription changes may require completely new lenses to be manufactured.
Our eye doctors evaluate your eye health, vision needs, lifestyle, and motivation to determine if scleral lenses are appropriate. A comprehensive consultation including corneal mapping and vision testing can help identify whether these specialized lenses would benefit your specific condition. We consider all factors before recommending this treatment option.
We keep your lens measurements and specifications on file and can order replacement lenses when needed. Manufacturing replacement lenses typically takes two to four weeks. Backup lenses are often recommended for patients who depend on their scleral lenses for daily activities. We can discuss backup options during your fitting process.
Most people find scleral lenses very comfortable because they rest on the less sensitive tissue covering the white part of your eye rather than directly on the cornea. The lenses tuck under your eyelids, so you feel less lid interaction compared to smaller contacts. Proper fit and handling techniques help maximize comfort throughout the day.
Yes, scleral lenses create a continuous fluid reservoir that hydrates and protects your cornea all day long. This makes them excellent for treating severe dry eye conditions that do not respond well to eye drops, punctal plugs, or other treatments. Many patients experience significant relief from dry eye symptoms while wearing these lenses.
Wear time varies from person to person, but many patients progress to wearing their lenses for 12 or more hours daily. Some people benefit from removing their lenses midday to clean and refill with fresh saline, especially when first adjusting. Follow your eye doctor's instructions for safe daily wear times based on your specific needs and eye health.
Scleral lenses are very stable and unlikely to fall out during normal activities. The larger diameter sits securely under your eyelids and centers well on your eye. Once you become skilled at inserting them properly, they stay in place reliably throughout your daily activities including exercise and sports.
If you notice a bubble after insertion, remove the lens, refill it completely with sterile saline, and reinsert it properly. Bubbles can cause blurred vision and localized dryness, so they should not be ignored. With practice, you will learn to avoid bubbles during insertion by filling the lens completely and inserting it smoothly.
Most scleral lenses last one to two years with proper care and handling. The exact lifespan depends on the lens material, how well you care for them, your individual eye chemistry, and how often you wear them. Your eye doctor will help determine the best replacement schedule based on regular evaluations of your lenses and eye health.
Most activities are possible with scleral lenses including swimming, sports, exercise, and outdoor activities. The lenses provide excellent stability and protection. However, avoid activities with high risk of eye trauma. For swimming, some doctors recommend removing lenses to prevent contamination, while others approve swimming with proper precautions.
When traveling, bring extra supplies including backup lenses if available, cleaning solutions, saline for filling, and your lens case. Pack supplies in both carry-on and checked luggage. Bring a letter from your eye doctor explaining your medical need for the solutions to help with airport security.
Stop wearing your lenses immediately and contact our office if you develop symptoms of infection including pain, redness, discharge, or vision changes. Do not resume lens wear until cleared by your eye doctor. Most infections can be treated successfully with prompt medical attention and proper antibiotic therapy.
Yes, children can wear scleral lenses if they are mature enough to handle insertion, removal, and care responsibilities. Age alone is not the determining factor - maturity, motivation, and ability to follow instructions are more important. Parents must be involved in the care routine and follow-up appointments.
Initially, follow-up visits are scheduled frequently to monitor fit and comfort. After the first few months, most patients need check-ups every six months to one year. However, you should schedule an appointment sooner if you experience any problems or changes in vision or comfort.
Good candidates have realistic expectations, motivation to learn proper care techniques, adequate hand dexterity for handling, and eye conditions that would benefit from scleral lens correction. Patients must be willing to commit to proper lens care and regular follow-up appointments for long-term success.
