Ocular Surface Diseases Commonly Managed with Scleral Lenses
Ocular Surface Disease Conditions We Treat with Scleral Lenses
When your eyes cannot produce enough tears or your tears evaporate too quickly, severe dry eye can make every blink painful. Sjögren syndrome, an autoimmune condition, often causes extreme dryness that does not respond well to artificial tears alone.
We typically try anti-inflammatory drops, prescription secretagogues, eyelid treatments, moisture strategies, and other medical therapies before considering scleral lenses. When these measures are insufficient, scleral lenses hold a reservoir of sterile saline solution against your cornea throughout the day. This fluid cushion protects the ocular surface, reduces friction, and can allow the cornea to heal while you wear the lens.
These serious systemic conditions can devastate the ocular surface, causing severe scarring, loss of goblet cells, and eyelid margin abnormalities. Eyes affected by Stevens-Johnson syndrome or graft-versus-host disease often develop chronic inflammation and corneal breakdown despite aggressive medical therapy.
Scleral lenses provide a protective barrier that shields fragile tissue from the eyelids during blinking. We may recommend them as part of a comprehensive plan that includes immunosuppressive drops, serum tears, and careful monitoring for infection or worsening inflammation. These eyes carry a heightened risk of infection, and lens wear may be limited by severe eyelid scarring or surface abnormalities, so we follow patients very closely and adjust the plan as needed.
When corneal nerves are damaged by infection, surgery, or systemic disease, your cornea loses its ability to sense injury and heal normally. Exposure keratopathy occurs when incomplete eyelid closure leaves part of the cornea vulnerable to drying and damage.
- Scleral lenses maintain moisture even when blinking is impaired
- The reservoir maintains a protective, hydrated environment; oxygen delivery depends on lens material, thickness, and reservoir depth, so we fit and monitor carefully
- In appropriate stages, we may combine lens therapy with epithelial healing treatments such as topical nerve growth factor or amniotic membrane approaches
- Regular monitoring ensures early detection of silent ulcers or infections
Chemical or thermal burns to the eye can destroy the limbal stem cells that normally regenerate the corneal surface. Without these stem cells, the cornea may become covered by abnormal conjunctival tissue, leading to scarring, pain, and vision loss. Limbal stem cell deficiency can also occur from chronic inflammation, severe allergic eye disease, or multiple surgeries.
Scleral lenses protect the fragile, unstable surface and provide hydration and optical improvement while we pursue medical or surgical treatments to restore the stem cell population. We often co-manage these complex cases with corneal specialists who may recommend amniotic membrane grafts, stem cell transplantation, or other advanced therapies alongside the scleral lens.
Corneal Shape Disorders We Manage with Scleral Lenses
Keratoconus causes your cornea to thin and bulge into a cone shape, distorting vision and making standard glasses or soft contacts ineffective. Scleral lenses create a smooth refracting surface over the irregular cornea and can provide clearer, more stable vision for many patients. While scleral lenses improve vision and comfort, they do not stop the progression of keratoconus; treatments such as corneal cross-linking may be considered to slow disease advancement.
We also fit scleral lenses for other ectatic conditions such as pellucid marginal degeneration and post-LASIK ectasia. These lenses offer superior comfort compared to smaller rigid gas permeable designs because they do not touch the sensitive corneal surface.
Scars left by trauma, herpes keratitis, or bacterial ulcers can create irregular surfaces that scatter light and blur vision. Traditional contact lenses often fail to mask these irregularities or may rub uncomfortably against raised scar tissue.
- Scleral lenses vault completely over scars without touching them
- The fluid layer fills in surface irregularities for clearer optics
- Reduced mechanical irritation can lessen epithelial breakdown and improve comfort while the surface stabilizes
- Custom vault depths accommodate even prominent scarring
Complications from corneal transplants, radial keratotomy, or other eye surgeries can leave you with unpredictable astigmatism that glasses cannot correct. Scleral lenses can neutralize many of these optical irregularities by replacing the irregular corneal surface with a smooth refracting surface. In eyes with corneal transplants, filtering blebs, or recent suture placement, we work closely with your corneal specialist to ensure scleral lens wear is safe and timing is appropriate.
Our eye doctor works closely with your surgeon to time the fitting appropriately, typically waiting until your eye has stabilized after the procedure. We adjust the lens design as your cornea continues to heal and change shape over the months following surgery.
Recognizing Symptoms and When to Seek Care
Blurred or fluctuating vision that improves briefly when you blink may indicate an unstable tear film or irregular cornea. You might notice glare, halos around lights, or difficulty reading even with updated glasses.
Progressive vision loss, especially if glasses no longer help, warrants a comprehensive evaluation. Our eye doctor will determine whether the problem stems from the ocular surface or another part of the eye.
Ocular surface disease often causes a gritty, burning sensation that worsens as the day goes on. You may feel like something is stuck in your eye even when nothing is there.
- Sharp or stabbing pain can signal corneal erosion or ulceration
- Severe light sensitivity may indicate inflammation or nerve damage
- Constant tearing sometimes paradoxically accompanies severe dryness
- Mucus discharge suggests inflammation or poor tear quality
If you find yourself using artificial tears every hour or waking with painful, stuck eyelids, your condition likely exceeds what over-the-counter drops can manage. Dependence on thick gels or ointments that blur vision signals a need for stronger intervention.
Our eye doctor evaluates why standard treatments are failing and considers options like prescription medications, punctal plugs, intense pulsed light therapy, or scleral lenses. We create a personalized treatment approach based on the underlying cause and severity of your symptoms.
Sudden vision loss, severe eye pain, or the appearance of new floaters or flashes demands immediate attention. A white spot on the cornea, thick yellow or green discharge, or inability to open the eye due to pain are urgent warning signs.
Contact our office right away if you experience sudden worsening of redness, extreme light sensitivity that prevents you from opening your eyes, or any trauma to the eye. These symptoms may indicate infection, ulceration, or other sight-threatening complications that require same-day treatment.
If you wear scleral lenses, remove the lens immediately and call our office the same day if you notice any of the following:
- Increasing pain or discomfort that persists after lens removal
- New or worsening light sensitivity
- Sudden reduction in vision
- Increasing redness that does not resolve quickly after removing the lens
- Any discharge, especially yellow or green
- A white or hazy spot on the cornea
- Inability to keep your eye open due to pain
Diagnostic Testing and Fitting Evaluation
Your first visit includes a detailed discussion of your symptoms, medical history, previous treatments, and how your condition affects daily life. We perform a comprehensive eye examination to assess vision, measure eye pressure, and evaluate the health of all ocular structures.
Our eye doctor examines the front surface of your eye using a slit lamp microscope, looking for signs of dryness, inflammation, scarring, or irregular shape. We also check how well your eyelids close and whether they distribute tears evenly across the surface.
These imaging technologies map the shape and thickness of your cornea with extreme precision. Topography captures thousands of elevation points to reveal even subtle irregularities, while tomography provides cross-sectional views of corneal layers.
- Color-coded maps show areas of steepening or flattening
- Measurements guide the initial lens design and diameter
- Follow-up scans track whether your cornea is stable or changing
- Advanced analysis detects early ectasia or post-surgical complications
We apply special dyes that highlight areas of corneal or conjunctival damage under blue or yellow light. The pattern and location of staining help us understand which parts of the ocular surface are most compromised.
Tear testing measures how much tear fluid you produce, how quickly it evaporates, and whether it contains adequate oil, water, and mucin layers. We may also test tear osmolarity and look for inflammatory markers that guide our treatment recommendations.
We typically start with diagnostic trial lenses in a range of sizes and vault depths. You wear each trial lens while we assess the fit using the slit lamp, checking for proper alignment, adequate clearance, and edge positioning.
The goal is a lens that vaults evenly over the cornea without touching it, lands gently on the sclera without blanching blood vessels, and maintains healthy reservoir thickness without excessive suction. Once we identify the optimal parameters, we order your custom lenses, which typically arrive within one to three weeks depending on the laboratory and design complexity.
How Scleral Lenses Treat Ocular Surface Disease
The space between the back of the lens and your cornea fills with sterile saline when you insert the lens. This fluid reservoir bathes the cornea throughout wear, helping to maintain hydration and protecting it from the friction of blinking.
The therapeutic vault shields damaged or irregular corneal tissue from environmental irritants, wind, and debris. For many patients, this moisture and protection can allow the ocular surface to heal in ways that were not possible with other treatments.
We consider scleral lenses when glasses cannot provide adequate vision, when smaller contact lenses cause discomfort or fall out, or when medical treatments alone do not control symptoms. They are often the best choice for severe irregularity, advanced dry eye, or conditions where corneal protection is critical.
- Smaller rigid lenses often center poorly on irregular corneas
- Soft lenses conform to irregularities rather than masking them
- Glasses cannot correct higher-order aberrations from corneal distortion
- Scleral lenses combine optical correction with therapeutic hydration
Mini-scleral lenses measure between 15 and 18 millimeters in diameter, while larger designs can exceed 20 millimeters. The choice depends on your eye anatomy, the extent of corneal irregularity, and how much scleral support you need.
Smaller diameters are easier to handle and require less filling solution, but larger lenses may center more reliably and provide greater stability on highly irregular eyes. Our eye doctor selects the diameter that balances comfort, vision, and ease of use for your specific situation.
Modern scleral lenses can be customized in hundreds of ways to match your unique eye shape and surface condition. We can adjust the central vault, peripheral curves, edge lift, and overall diameter based on what we observe during fitting.
For eyes with significant asymmetry or scarring, we may incorporate toric or quadrant-specific designs. In selected cases, fenestrations or venting features may be considered, though they can increase bubble risk and are not used routinely. We can also modify edge profiles and tint the lens periphery to enhance comfort in bright light.
Scleral lenses work best as part of a comprehensive treatment plan. We may recommend continuing anti-inflammatory drops, immunosuppressive agents, or autologous serum tears even after you begin wearing lenses.
- Prescription drops are usually instilled before lens insertion or after removal
- Punctal plugs can be retained to maximize your natural tear volume
- In-office procedures like intense pulsed light or LipiFlow may complement lens therapy
- We coordinate care with your rheumatologist or other specialists as needed
- Regular follow-up ensures that all treatments work together safely and effectively
Wearing and Caring for Your Scleral Lenses
Inserting a scleral lens requires a different technique than inserting a soft contact lens. You fill the lens bowl with sterile saline, lean over a mirror, hold your eyelids open wide, and gently place the lens on your eye in one smooth motion.
Our staff will train you step-by-step and watch you practice until you feel confident. Most patients master insertion and removal within the first or second training session, though it may take a few weeks to become quick and comfortable with the process.
You must fill your scleral lens with preservative-free sterile saline each time you insert it. Preserved solutions or tap water can damage your cornea or cause serious infections.
- Use only preservative-free sterile saline designed for scleral lens filling, in single-use vials or multi-use bottles approved for this purpose
- Avoid touching the vial or bottle tip to any surface; discard if tip contamination occurs
- Discard any saline remaining in an opened single-use vial after that insertion
- Never top off partially used containers or reuse saline from the previous day
- Check expiration dates and store unopened saline in a cool, dry place
After removing your lenses each day, rinse them thoroughly with the prescribed cleaning solution and rub gently to remove protein and debris. Rinse again with fresh solution before placing the lenses in a clean storage case filled with the recommended disinfecting solution.
Replace your lens case every one to three months to prevent biofilm buildup. Never use tap water, saliva, or homemade solutions to clean or store your lenses, as these can introduce harmful microorganisms.
Scleral lenses typically last one to three years with proper care, though some patients need replacements sooner if their eyes change or lenses become damaged. We may recommend earlier replacement if deposits build up despite cleaning or if vision becomes inconsistent.
Contact our office promptly if you notice sudden discomfort, redness that persists after lens removal, changes in vision, visible cracks or chips in the lens, or if the lens no longer centers properly. Do not continue wearing a damaged lens, as it can scratch or injure your cornea.
Foggy or cloudy vision during wear often means debris is trapped under the lens, an air bubble formed during insertion, or the vault is too tight and limiting fluid flow. Removing, cleaning, and reinserting the lens usually resolves the problem.
If the lens feels uncomfortable or moves excessively, the diameter may be too small or the edge profile may not match your scleral shape. Persistent redness at the lens edge suggests the landing zone is too tight and we need to modify the design. Report any ongoing issues so we can adjust the fit rather than tolerating discomfort.
Follow-Up Care, Safety, and Risks
We commonly schedule follow-up appointments at intervals such as one day, one week, one month, and three months after you receive your new lenses, though the exact schedule varies based on your diagnosis and how your eyes respond. These visits allow us to check the fit, assess corneal health, and make any needed adjustments.
- Early visits catch fit issues before they cause complications
- We may modify lens parameters if clearance is too tight or too loose
- Corneal staining patterns guide refinements to edge alignment
- After the initial series, most patients need check-ups every six to twelve months
While scleral lenses are generally safe when used properly, they do carry risks. Microbial keratitis is the most serious complication and can occur if lenses are not cleaned and disinfected correctly or if contaminated water or solutions contact the lens. Other potential complications include corneal swelling from low oxygen, corneal or conjunctival staining, inflammation or allergic reactions, giant papillary conjunctivitis, limbal compression, conjunctival prolapse under the lens edge, tight lens or suction symptoms, and solution toxicity or preservative sensitivity. In patients with certain types of glaucoma, lens wear may raise eye pressure concerns and requires monitoring.
Scleral lenses should not be worn if you have an active eye infection or significant new symptoms such as pain, light sensitivity, or vision loss. You also may not be a good candidate if you are unable to safely handle, insert, remove, or disinfect the lenses, or if you have certain eye conditions such as active microbial keratitis, uncontrolled inflammation, or recent surgery with wound or bleb concerns. If any new symptoms develop, remove your lens immediately and contact our office for same-day evaluation.
Frequently Asked Questions
Scleral lenses manage symptoms and protect your cornea, but they do not cure the underlying disease. Many patients experience dramatic improvement in comfort and vision, yet the original condition remains and may progress if lenses are discontinued.
Most patients wear scleral lenses for twelve to sixteen hours daily, though the safe duration varies by individual. We base wearing time on your corneal health and the signs we see during follow-up visits, such as swelling, staining, or changes at the limbus that suggest the cornea is not getting adequate oxygen.
Many medical insurance plans cover medically necessary scleral lenses for conditions like keratoconus, corneal transplant, or severe dry eye, though coverage varies widely. Our billing team can verify your benefits and help with prior authorization paperwork.
We do not recommend sleeping in scleral lenses unless specifically prescribed for overnight therapeutic use in rare cases. Sleeping in lenses increases the risk of infection, reduces oxygen to the cornea, and can lead to serious complications.
If your disease progresses despite optimal lens wear, we reassess your entire treatment plan. Options may include adjusting medications, adding immunosuppressive therapy, considering surgical interventions like amniotic membrane transplant, or collaborating with corneal specialists for advanced procedures.
We strongly advise removing your lenses before swimming, showering, or any water exposure to avoid trapping bacteria, amoebae, or other pathogens under the lens. If water exposure is unavoidable, use watertight swim goggles and remove, clean, and disinfect your lenses immediately afterward. Contact our office promptly if you develop pain, redness, or vision changes after any water exposure.
