Scleral Lenses for Meibomian Gland Dysfunction
Understanding Meibomian Gland Dysfunction and Vision Challenges
Meibomian gland dysfunction happens when the tiny oil glands in your eyelids become blocked or stop producing healthy oils. These glands normally release a protective oil layer that keeps your tears from evaporating too quickly. When they do not work properly, your tears dry up faster than they should, leaving your eyes feeling scratchy, burning, and irritated.
Over time, blocked glands can become inflamed and may even stop working completely. This creates a cycle where poor oil quality leads to more irritation, which causes more inflammation, which makes the oil problem even worse.
You might notice that your vision gets blurry after reading or looking at screens for a while. This happens because your tear film becomes unstable without the right oil layer. Blinking usually clears things up for a moment, but the blurriness comes back quickly.
- Fluctuating vision that improves briefly when you blink
- Increased glare or halos around lights, especially at night
- Difficulty wearing your regular contact lenses for more than a few hours
- Feeling like you constantly need to rub or close your eyes
Regular soft contact lenses sit directly on your cornea and depend on your tears to stay moist and comfortable. When you have MGD, your tears evaporate too fast, so the lens starts to dry out. This creates friction between the lens and your eye surface, making irritation much worse.
Traditional contact lenses also absorb oils and proteins from your unstable tear film, which makes them cloudy and uncomfortable even faster than normal. Many people with MGD find they can only wear their regular contacts for an hour or two before their eyes become too irritated to continue.
How Scleral Lenses Work for Meibomian Gland Dysfunction
Scleral lenses are larger than traditional contacts and have a completely different design. Instead of resting on your cornea, they vault over the entire front surface of your eye and rest gently on the sclera, which is the white part surrounding your cornea. This creates a smooth optical surface for clear vision while protecting your sensitive cornea from exposure.
The edges of the lens land on tissue that has fewer nerve endings than your cornea, so most patients find scleral lenses very comfortable once they adjust to them. The lens diameter is often about 14 to 24 millimeters, including mini-scleral to larger designs, depending on the design and your eye shape.
Before you insert a scleral lens, we fill it with a sterile saline solution. This fluid generally remains in place during wear, creating a liquid cushion that bathes your eye, though some patients need to remove, clean, and refill during the day if fogging or debris occurs. For someone with MGD, this means your cornea stays hydrated even when your natural tears are poor quality.
- The fluid reservoir does not depend on your tear film to stay wet
- Your cornea gets continuous hydration and protection from air exposure
- The protected environment may support ocular surface recovery in some patients
- The lens moves very little when you blink, which reduces friction on the cornea
Because scleral lenses create their own fluid environment under the lens, they do not rely on your defective oil layer to function. Your tears still coat the outside front surface of the lens, but the health of your meibomian glands no longer determines whether the lens stays comfortable. This protected fluid reservoir with limited tear exchange can make a significant difference for people with MGD who have struggled with other types of contacts.
The reservoir also protects your cornea from environmental irritants like dust, pollen, and dry air that normally make MGD symptoms worse. Many patients report they can work on computers, drive at night, and participate in outdoor activities with improved comfort.
However, the front surface of the lens is still exposed to your evaporative dry eye environment, so front-surface drying and midday fogging can occur. We may recommend rewetting drops approved for use over scleral lenses, surface treatments, or midday removal and refill when needed to maintain clear vision and comfort.
We typically recommend scleral lenses for patients with moderate to severe MGD whose symptoms interfere with daily activities and who have not found adequate relief from other treatments. You may be a good candidate if standard contact lenses have become intolerable or if you need clear, stable vision throughout the day despite dry eye symptoms. Scleral lenses are usually considered when standard MGD therapy and conventional lenses are insufficient, and when there is significant ocular surface compromise or functional limitation.
Scleral lenses work well for people who have tried warm compresses, lid scrubs, and artificial tears but still struggle with comfort and vision quality. We also consider them for patients who have irregular corneas from other conditions alongside their MGD, since the lenses correct both issues at once. Active lid inflammation and blepharitis should be controlled to improve your success with scleral lenses.
- Active eye infection or uncontrolled eyelid inflammation
- Severe blepharitis or rosacea flare that is not being treated
- Difficulty with hand coordination or dexterity needed to handle lenses safely
- Reduced corneal sensation or neurotrophic cornea that may mask problems
- Inability to maintain proper lens hygiene or attend regular follow-up visits
Getting Evaluated and Fitted for Scleral Lenses
During your evaluation, we examine your eyelid margins under magnification to see how many glands are blocked and whether the openings show signs of inflammation. We may gently press on your lids to check the quality and flow of the oil that comes out. Healthy oil should be clear and flow easily, while thick, toothpaste-like secretions or no flow at all indicate moderate to severe dysfunction.
We also use special imaging to look at the structure of your meibomian glands through your eyelids. This helps us see how many glands have atrophied or stopped functioning. Other tests measure how quickly your tears evaporate and how stable your tear film remains between blinks, which helps us understand the severity of your condition.
Fitting scleral lenses requires very precise measurements of your eye surface. We use advanced imaging technology called corneal topography to create a detailed map of your cornea's shape and curvature. Many practices also use scleral shape assessment and anterior segment imaging to evaluate the landing zone. This map guides us in selecting the best starting lens design for your eyes.
- We measure the diameter of your cornea and the surrounding sclera
- We assess the height and steepness of your corneal curve
- We evaluate the angle where your cornea meets your sclera
- We check for any irregular areas that need special lens design features
Your first fitting appointment usually takes longer than a routine eye exam because we test several trial lenses to find the right fit. We look at how the lens vaults over your cornea, how it lands on your sclera, and how the fluid reservoir distributes across your eye surface. We also check your vision through each lens and make sure you can see clearly, though you may still need reading glasses or other vision correction depending on your prescription.
We use special dyes and lights to evaluate the space between the lens and your eye. The goal is to achieve adequate clearance over your cornea without creating too much or too little fluid volume. We may try multiple designs during this visit, and we teach you how to insert and remove the lenses before you leave.
After we determine the best lens design for you, we order your custom scleral lenses from the laboratory, which typically takes two to three weeks. When your lenses arrive, you return for a dispensing visit where we verify the fit and train you on proper insertion, removal, and care techniques.
Most patients need at least one follow-up visit within the first few weeks to check how your eyes are responding and whether any adjustments are needed. Plan on a total of three to five visits over the course of two to three months to complete your fitting process. Some patients achieve a perfect fit more quickly, while others with more complex eye shapes may need additional refinements. We may recommend that you gradually increase your wearing time during the first few weeks as your eyes adjust.
Wearing and Caring for Your Scleral Lenses with MGD
Most patients use a small suction tool called a plunger to handle scleral lenses safely. To insert your lens, you fill it completely with sterile saline while it rests on the plunger, then lean over a mirror and guide the lens onto your eye in one smooth motion. The trick is to keep the fluid from spilling while you lower your lids around the lens edges.
- Wash and dry your hands thoroughly before handling your lenses
- Fill the lens bowl to the brim with fresh saline solution
- Look straight down into a mirror placed on a flat surface
- Pull your lids wide apart with your free hand and seat the lens gently
- Use the plunger to remove the lens by pressing it onto the lower edge and breaking the seal
Every time you remove your lenses, we recommend cleaning them with a preservative-free contact lens cleaner designed for scleral lenses. Place a few drops of cleaner on each side of the lens and gently rub with your fingertip in a back-and-forth motion to remove oils, proteins, and debris. Rinse thoroughly with preservative-free saline before storing in fresh disinfecting solution overnight.
Because you have MGD, your lenses may accumulate more oil deposits than average. Pay special attention to cleaning the front surface where your oily tears come into contact with the lens material. Replace your lens case every month to prevent contamination, and never reuse old solution or top off partially used solution in your case.
- Clean by rubbing after removal with approved cleaner
- Disinfect overnight using the system we prescribe, often hydrogen peroxide for many scleral wearers
- Never store or disinfect lenses in plain saline
- Rinse only with approved sterile solutions, never tap water
- Air-dry your case and replace it per product instructions, often with each peroxide kit or at least monthly
Protecting your lenses and eyes from contamination is critical to preventing serious infections. Water from taps, showers, pools, and hot tubs contains microorganisms that can cause severe eye infections, including Acanthamoeba keratitis, which is difficult to treat and can threaten your vision.
- Never rinse lenses with tap water, bottled water, or homemade saline
- Remove lenses before showering, swimming, or using hot tubs
- Wash and thoroughly dry your hands before handling lenses
- Use only sterile, preservative-free saline from sealed single-use vials for filling
- Never top off or reuse solutions in your lens case
- Remove lenses immediately and contact us if you experience pain, light sensitivity, discharge, or sudden vision changes
- Do not reinsert lenses if your eyes are red or painful until we have examined you
We typically recommend using preservative-free sterile saline in single-use vials intended for scleral lens filling, as directed by your clinician. Preservatives can irritate your already sensitive eyes and may interfere with your MGD treatment. Do not use multi-dose bottles after opening unless we specifically instruct you to do so, and never use any non-sterile water.
Some patients with very sensitive eyes do better with a buffered saline solution that more closely matches the natural chemistry of healthy tears. We may recommend trying different filling solutions if you experience stinging or unusual cloudiness during the day. Always use fresh saline for each insertion and discard any leftover solution from opened vials. Do not fill your lenses with multipurpose disinfecting solution or anything preserved unless we specifically direct you to do so.
Even with excellent daily cleaning, scleral lenses worn by people with MGD tend to develop stubborn deposits over time. MGD often causes lipid deposits and front-surface wetting problems in addition to protein buildup. Management may include specific cleaners for rigid gas permeable materials, periodic deep cleaning in our office, and surface treatments or coatings as we prescribe.
We may recommend using an enzyme-based protein remover once or twice a week to break down buildup that regular cleaners cannot eliminate. Follow the instructions carefully, as some protein removers require specific soaking times and neutralization steps. Contact our office before increasing the frequency of enzymatic or aggressive cleaning, as overuse can damage lenses or irritate your eyes.
- Inspect your lenses daily for cloudy areas or visible deposits
- Report reduced vision clarity or wetting problems at follow-up visits
- Bring your lenses to appointments so we can check for deposits
- Consider professional deep cleaning if home care does not keep lenses clear
Most patients can safely wear scleral lenses for 10 to 14 hours per day once they complete the adjustment period. We usually recommend starting with just four to six hours on the first day and adding an hour or two each day as your eyes adapt. Take breaks if your eyes feel tired, and always remove your lenses before sleeping unless we specifically prescribe extended wear for your situation.
Scleral lenses typically last one to two years with proper care, though some patients need replacement sooner if deposits accumulate or the lens material changes. We schedule regular checkups every six months to monitor your lens condition and ensure the fit remains appropriate as your eyes change over time.
Combining Scleral Lenses with MGD Treatment
Scleral lenses relieve your symptoms, but they do not cure the underlying meibomian gland dysfunction. We recommend that you continue your lid hygiene routine every day, even when your eyes feel great. Warm compresses and lid scrubs help keep your glands as healthy as possible and reduce the inflammation that drives MGD progression.
The best time to perform lid hygiene is usually in the evening after you remove your lenses. This prevents any cleansers or oils from interfering with lens insertion and ensures your lids are clean before overnight tear production begins. Consistent lid care may also extend the time between lens cleanings by reducing the amount of debris that reaches your lenses.
Many prescription drops are best used before insertion or after removal. Only use medicated drops over lenses or in the reservoir if we specifically instruct you to do so. Timing matters because some drops may cloud the fluid reservoir or interact with the lens material in ways that reduce comfort or vision.
- Do not place preserved drops into the lens bowl or reservoir
- Ask us specifically about using antibiotics, steroids, or glaucoma drops with your lenses
- Wait at least 10 minutes after drops before inserting lenses if we approve morning use
- Remove lenses immediately and contact us if a drop causes stinging, haze, or unusual fogging
We may recommend in-office treatments like thermal pulsation or meibomian gland expression to improve your gland function even while you wear scleral lenses. These procedures work directly on your eyelids and do not interfere with lens wear, though we usually ask you to skip wearing your lenses on treatment day to give your eyes time to settle.
Plan to take a day or two off from lens wear after more intensive procedures, as your lids may feel tender or produce extra discharge during initial healing. Once any post-procedure irritation subsides, you can resume your normal lens schedule. Some patients find their lenses feel even more comfortable after successful gland treatments because their natural tear quality improves.
Omega-3 fatty acid supplements may support healthier oil production in your meibomian glands when taken consistently over several months. We may recommend a high-quality fish oil or algae-based omega-3 supplement as part of your overall MGD management plan. While supplements alone rarely resolve severe MGD, they can complement other treatments and potentially slow disease progression.
Staying well hydrated and eating a balanced diet rich in anti-inflammatory foods also supports eye health. Some patients notice that avoiding excessive caffeine and alcohol helps reduce their dry eye symptoms. Discuss any supplements with us before starting them, as some may interact with other medications or health conditions.
Recognizing Problems and When to Seek Care
While scleral lenses offer significant benefits for many people with MGD, they carry risks and limitations that you should understand. Being aware of these helps you make informed decisions and recognize when problems arise.
- Risk of serious eye infection, especially if water or hygiene protocols are not followed strictly
- Possibility of corneal swelling or reduced oxygen supply if fit is too tight or wearing time is excessive
- Midday fogging or debris accumulation that may require removal and refill during the day
- Increased deposit burden from MGD-related oils that require diligent cleaning
- Significant cost and time commitment for fitting, follow-up, and lens replacement
- Need to continue treating underlying MGD even when lenses provide symptom relief
During your first week or two with scleral lenses, you may feel more aware of the lens edges when you blink or move your eyes. This sensation usually fades as your eyes adapt to the new lens size. Some people notice extra tearing or mild redness at first, which is a normal response as your eyes adjust to the different fit.
You might also experience slight fogging or bubbles under the lens during the initial adaptation period. These issues often improve as you refine your insertion technique and as your eyes become accustomed to the fluid reservoir. Mild end-of-day dryness on the front lens surface is common and usually responds well to rewetting drops applied to the outside of the lens.
If you notice consistent discomfort at specific points on the lens edge, or if you see indentations on your eye surface after removing the lenses, the fit may be too tight in certain areas. Vision that suddenly becomes less clear or more variable than when you first got your lenses can indicate that the lens has warped or your eye shape has changed. Persistent fogging that does not clear with cleaning or refilling suggests the vault height may need adjustment.
- Lenses that move excessively when you blink or look around
- Bubbles that appear under the lens during wear and cause blur
- Discomfort that gets worse instead of better after the first month
- Difficulty achieving clear vision even after cleaning and refilling
Remove your lenses immediately and contact our office if you experience sudden sharp pain, significant vision loss, or intense light sensitivity. These symptoms may indicate a corneal injury or infection that needs prompt treatment. Any discharge that is thick, yellow, or green signals possible infection and should never be ignored. Do not reinsert your lenses until we have examined you and cleared you to resume wear.
Severe redness that appears quickly and does not improve within an hour of removing your lenses also warrants urgent evaluation. If you notice a white or gray spot on your cornea, or if your eye becomes increasingly painful despite removing the lens, seek care the same day. If you cannot reach us promptly, seek urgent or emergency eye care. Quick action can prevent serious complications and protect your vision.
Take a break from wearing your lenses if your eyes become consistently red, irritated, or uncomfortable, even if the symptoms are mild. This gives us a chance to examine your eyes and determine whether the problem stems from the lens fit, a care routine issue, or an unrelated eye condition. Also pause lens wear if you develop a cold, sinus infection, or allergies that make your eyes feel worse than usual.
Call our office for guidance if you break or damage a lens, lose a lens, or run out of approved cleaning solutions. Do not substitute unapproved products or try to wear a damaged lens. After any episode of redness or pain, bring your lenses, case, and solutions to the visit if possible so we can evaluate all components of your lens system.
Frequently Asked Questions
Scleral lenses do not directly harm your meibomian glands because they vault over your cornea and do not rest on your eyelid margins where the glands are located. However, if you stop doing your regular MGD treatments because your eyes feel better in lenses, the underlying gland dysfunction may continue to progress. We recommend using scleral lenses as part of a complete MGD management plan that includes ongoing lid hygiene and medical treatment.
Most patients with MGD can comfortably wear scleral lenses for 10 to 14 hours daily once they finish the adjustment period. Your individual wearing time may vary depending on how severe your dry eye is and how your eyes respond to the lenses. We monitor your corneal health at regular checkups to make sure extended lens wear is not causing any problems beneath the fluid reservoir.
Yes, you should continue treating the root cause of your meibomian gland dysfunction even when scleral lenses eliminate your symptoms. The lenses mask discomfort but do not fix blocked or inflamed glands. Keeping up with warm compresses, lid scrubs, medications, and any in-office treatments we recommend gives you the best chance of preserving your remaining gland function and potentially reducing your dependence on lenses in the future.
Insurance coverage for scleral lenses varies widely depending on your specific plan and whether we document medical necessity. Some medical insurance policies cover a portion of the cost when lenses are prescribed for severe dry eye disease, while vision insurance plans rarely cover specialty contact lenses. Our staff can help you understand your benefits and provide the documentation your insurer requires, though you should be prepared for significant out-of-pocket expenses.
While most patients with MGD experience significant relief from scleral lenses, a small percentage may continue to have symptoms or develop new problems. If this happens, we work with you to identify the cause, which might include adjusting the lens fit, changing your care routine, or addressing other eye conditions that coexist with your MGD. In some cases, we may explore alternative treatments such as specialized eyewear, moisture chamber glasses, or more intensive medical therapy for your underlying condition.
