The HERO Ultimate Scleral Lens
Who Can Benefit from the HERO Ultimate Scleral Lens
Keratoconus causes your cornea to thin and bulge into a cone shape, making vision blurry and distorted. HERO lenses vault over the irregular surface and form a new optical front for your eye. This design corrects the vision problems that glasses and regular contacts cannot address.
People with other types of corneal irregularities, such as pellucid marginal degeneration or corneal ectasia, also benefit from this lens technology. The custom fit accommodates your unique corneal shape while providing crisp vision throughout the day.
When you have severe dry eye, your eyes may burn, sting, or feel gritty even with eye drops. HERO lenses create a fluid reservoir between the lens and your cornea that keeps your eye surface moist all day. This protective layer often reduces discomfort and can improve your quality of life.
We may recommend these lenses for conditions like Sjögren syndrome, graft-versus-host disease, or Stevens-Johnson syndrome that damage your ocular surface. The constant fluid cushion protects delicate tissues and may support healing in ways that other treatments cannot. These medically complex conditions require close medical oversight and may involve concurrent therapies.
Some eyes develop irregular surfaces after corneal transplants, LASIK, PRK, or radial keratotomy. These irregular surfaces can leave you with vision that glasses cannot sharpen. HERO lenses mask the irregularities and can improve functional vision in many cases, depending on scarring and ocular health.
- Corneal transplant patients with astigmatism or surface bumps
- Irregular astigmatism after refractive surgery with higher-order aberrations
- Corneal scars from injury or infection
- Eyes with irregular healing after other procedures
If you have extreme nearsightedness, farsightedness, or astigmatism, regular contacts may not provide clear vision or a stable fit. HERO lenses can correct much higher prescriptions because of their large diameter and custom parameters. The lens vaults over your cornea instead of moving with each blink, giving you steadier vision.
High astigmatism becomes easier to correct when the lens sits on the sclera rather than the cornea. Our eye doctor can fine-tune the prescription to match your exact needs, often achieving better results than standard soft lenses and many other designs for this indication.
Many rare or complex eye conditions leave people struggling with poor vision despite trying every standard option. HERO lenses offer hope when nothing else has worked. We use these lenses for conditions like persistent corneal erosions and neurotrophic keratopathy, though these medically complex conditions require close oversight and may involve concurrent therapies. Elevated conjunctival lesions like pinguecula or pterygium may require specialized edge modifications to work around the raised tissue.
Some patients have unique combinations of problems, such as dry eye plus irregular astigmatism, that require the multipurpose benefits of scleral lens technology. The HERO system gives us the flexibility to address several issues at once with a single solution.
What Makes the HERO Ultimate Scleral Lens Different
The HERO Ultimate lens uses proprietary design features that set it apart from other scleral lenses. Its engineering allows us to customize more variables than standard scleral designs, matching your eye anatomy with precision. This extra control helps us solve difficult fitting challenges that might fail with simpler lens types.
- Multiple zones for independent adjustment of fit and optics
- Advanced edge profiles that reduce awareness and improve comfort
- Material options that maximize oxygen flow to your eye
- Design flexibility for eyes with unusual shapes or conditions
Unlike regular contacts that rest on your cornea, HERO lenses arch completely over it and land on the sclera. The space between the lens and your cornea fills with sterile saline solution that we place in the lens before you insert it. This fluid vault keeps your cornea bathed in moisture and creates a perfectly smooth optical surface.
The lens is designed to vault the cornea, and we verify clearance at fitting and at follow-up visits because the lens can settle over the day. This vault design protects sensitive or damaged tissue. The lens reduces evaporation and shields the surface, though comfort also depends on underlying inflammation and lid and tear factors.
We create your HERO lens using detailed measurements from advanced imaging devices that map every curve of your eye. The technology captures thousands of data points across your cornea and sclera. Our eye doctor analyzes this information to design a lens that matches your unique contours.
Each HERO lens is manufactured specifically for your individual eye, not selected from a limited set of standard sizes. This personalized approach means better comfort, healthier eyes, and clearer vision than you could achieve with mass-produced lenses.
HERO lenses typically provide sharper vision than soft lenses for people with irregular corneas or high astigmatism. The rigid material holds its shape on your eye, maintaining optical clarity that soft lenses cannot match. Many patients report seeing better with HERO lenses than they have in years, with some achieving vision close to normal.
- Stable vision that does not blur with blinking
- Correction of higher-order aberrations that glasses leave behind
- Consistent focus throughout the day without dryness-related fluctuation
- Better contrast and night vision compared to distorted corneal optics
Scleral lenses are one of several vision correction options we may consider for your eyes. Other approaches include custom soft toric lenses, corneal rigid gas permeable lenses, hybrid lens designs, and traditional spectacles. Some patients benefit from piggyback systems that combine different lens types.
For specific conditions, we also consider medical and surgical alternatives. Keratoconus patients may be candidates for corneal cross-linking to stabilize progression. Severe dry eye may improve with additional medical therapies. Our eye doctor will discuss which options are most appropriate for your individual situation.
The Fitting Process for HERO Lenses
Your first appointment includes a complete eye examination to determine if HERO lenses are right for you. We check your overall eye health, measure your prescription, and review your vision history. Our eye doctor discusses your specific needs and explains what you can expect from the fitting process.
We also evaluate any eye conditions that need treatment before we fit lenses, such as inflammation or infection. Starting with healthy eyes gives you the best chance for a successful outcome with your new lenses.
We use specialized instruments to create detailed maps of your corneal shape and measure your eye dimensions. Corneal topography shows us every bump and valley on your corneal surface. Optical coherence tomography may help us see the exact vault we need to design into your lens.
- Corneal topography to map surface irregularities
- Scleral shape analysis to guide lens landing zone design
- Anterior segment imaging to measure eye structures
- Pupil and iris measurements for proper lens centration
We select diagnostic lenses based on your measurements and have you try them in our office. You will learn to insert and remove lenses during these visits while we supervise and guide you. We check how each trial lens fits using a microscope and special dyes that highlight the fluid layer.
This process helps us see if the lens vaults correctly over your cornea, lands evenly on your sclera, and moves appropriately with blinking. We may try several different lenses to find the parameters that work best for your eyes.
After we determine the best base design, we order your custom HERO lenses from the laboratory. When your lenses arrive, you return so we can verify the fit and check your vision. We may request modifications if anything needs adjustment to optimize comfort or visual performance.
Fine-tuning might involve changing the vault height, adjusting the edge lift, or refining the prescription. This step ensures you receive the best possible vision and comfort from your final lenses.
Most patients complete the HERO fitting process over several weeks to a few months. The timeline depends on how complex your eyes are and how many adjustments we need. Simple cases may succeed quickly, while challenging eyes require more trials and modifications.
- Initial evaluation and imaging: one appointment
- Diagnostic fitting sessions: one to three appointments
- Manufacturing time for custom lenses: two to four weeks
- Verification and training: one to two appointments
- Follow-up adjustments if needed: additional visits as required
Inserting, Wearing, and Caring for Your HERO Lens
We teach you a specific technique for inserting HERO lenses using a small plunger or your fingers. You fill the lens bowl with sterile saline solution, lean over a mirror, and gently place the lens on your eye. The process takes practice, but most people master it within a few tries.
Removal uses a different small plunger designed to break the seal between your eye and the lens. Our staff works with you until you feel confident handling your lenses independently at home.
If a lens ever feels stuck, do not force it. Apply lubricating drops or preservative-free saline to the eye, wait a moment, and try the correct plunger technique again. If you are unable to remove a lens safely, call our office for guidance.
Preventing infection is critical when wearing contact lenses. Water carries microorganisms that can cause serious eye infections, so strict water avoidance protects your eyes. Following simple hygiene rules keeps your lenses safe and your eyes healthy.
- Never use tap water to rinse lenses, clean your lens case, rinse plungers, or fill the lens bowl
- Do not shower, swim, or use hot tubs while wearing lenses; always remove lenses before any water exposure
- Wash and dry your hands thoroughly with a lint-free towel before handling lenses
- Clean plungers with approved solutions and let them air dry; replace them periodically as recommended
- If water contacts your lens or eye while wearing lenses, remove the lens immediately, clean and disinfect it properly, and monitor for symptoms
- Call our office right away if you develop pain, redness, or light sensitivity after water exposure
Every night, you remove your lenses and clean them with an approved cleaner designed for rigid gas permeable lenses. Understanding the difference between product types helps you use them safely. A cleaner is a daily surfactant or approved solution you rub on the lens to remove debris. A disinfectant is the solution you store lenses in overnight, such as peroxide systems or chemical disinfection solutions. Sterile non-preserved saline is only for filling the lens bowl before insertion, never for cleaning or disinfecting.
We will recommend products compatible with your lenses and ocular surface needs. You rub the lens gently between your fingers with cleaner, rinse thoroughly with the appropriate rinsing solution, and place it in fresh disinfecting solution overnight.
- Remove lenses and rinse with preservative-free saline or approved rinse
- Apply cleaner and rub both sides of each lens
- Rinse again to remove all cleaner residue
- Store in fresh disinfecting solution in a clean case
- Rinse with saline before insertion the next morning
Understanding what not to do is equally important for safety.
- Do not fill the lens bowl with disinfecting solution, peroxide, or multipurpose solution; use only sterile non-preserved saline
- Do not top off old solution or reuse saline from previous days
- Do not use saliva, homemade saline, or any non-approved liquids on your lenses
- Do not rinse lenses or your lens case with tap water
- Do not mix different types of solutions unless specifically directed by the manufacturer
Many patients can wear their HERO lenses for 12 to 16 hours daily once they adjust to them, though this is not a goal for everyone. We typically recommend starting with shorter wearing times, such as four to six hours, and gradually increasing as your eyes adapt. Your comfort, eye health, and specific condition determine your ideal wearing schedule.
Some people with severe dry eye may wear their lenses from morning until bedtime because the fluid reservoir keeps their eyes comfortable. Patients with corneal transplants, endothelial disease, or other conditions may need shorter wearing times. Remove your lenses earlier if you experience fogging, pain, increasing redness, or halos. Our eye doctor will give you personalized guidelines based on your specific condition and how your eyes respond.
Always store your HERO lenses in a clean case with fresh disinfecting solution. Never reuse old solution or mix new solution with leftover liquid in your case. Replace your lens case every one to three months to prevent bacterial buildup.
Keep your lenses away from water sources like sinks and showers where they could be exposed to harmful microorganisms. Store them in a safe spot where they will not be knocked over or contaminated by dust and debris.
HERO lenses typically last one to two years with proper care, though some may need replacement sooner if they develop deposits or scratches. We examine your lenses at follow-up visits to check their condition. When we notice signs of wear, we will order replacements to maintain your vision quality and eye health.
- Replace disinfecting solution daily, never topping off old solution
- Use fresh saline for insertion each morning
- Discard any solution bottle once opened for longer than recommended
- Schedule lens replacement when deposits build up despite cleaning
Adjusting to HERO Lenses and Follow-Up Care
Your eyes need time to adjust to wearing HERO lenses, even though they should feel comfortable from the start. You may notice slight awareness of the lenses initially, especially at the edges. This sensation usually fades within a few days to two weeks as your eyes adapt.
Your vision might seem very sharp right away or may improve gradually as your eyes adjust to the new optics. Some patients experience temporary lens fogging after a few hours of wear during the adaptation period, which typically resolves as your tear film stabilizes.
Mild redness around the area where the lens edge sits is normal at first and should decrease as you adapt. If you feel slight irritation, check that your lens is clean and properly centered on your eye. Removing, cleaning, and reinserting the lens often solves minor discomfort.
- Awareness of lens edges usually decreases within one to two weeks
- Brief fogging may occur but often clears with blinking or lens removal and reinsertion
- Slight redness should fade as your eyes adjust to lens wear
- Excessive tearing in the first days is normal and typically resolves quickly
While HERO lenses are very safe when used properly, all contact lenses carry some risks that we monitor carefully at your follow-up visits. Understanding these potential complications helps you recognize warning signs early and maintain healthy eyes.
- Infection, including microbial keratitis, is rare but serious; preventing it requires strict hygiene, no water exposure, and proper lens care
- Corneal staining, swelling, or reduced oxygen delivery can occur if lenses fit too tightly, vault excessively, or are worn too long
- Conjunctival blanching, impingement from lens edges, suction against the eye, or rebound redness may indicate fit problems
- Midday fogging and deposit buildup are common and often manageable by treating underlying blepharitis or dry eye, adjusting lens care, or modifying the lens design
- Patients with corneal transplants, endothelial disease, or glaucoma require additional monitoring for corneal swelling, clarity changes, or pressure concerns
- Blood vessel growth toward the cornea can develop in some eyes with oxygen stress or chronic inflammation
We design your follow-up schedule to catch any of these issues before they become serious. Most complications are preventable with proper care and regular monitoring.
We schedule your first follow-up visit within one to two weeks after you start wearing your lenses. During this appointment, we examine your eyes with the lenses on and after removal to check eye health and fit. We verify that the lenses are not causing any problems and that your vision meets expectations.
Additional follow-up visits occur at intervals we determine based on your condition, typically after one month, three months, and then every six months. These regular checks help us catch any issues early and keep your eyes healthy for the long term.
If your vision becomes blurry or unstable after an initial period of clarity, your lens might need modification. Persistent discomfort that does not improve with time may indicate a fit problem that we can correct. Excessive redness, especially in one specific area, suggests the lens may be pressing too hard or not landing evenly.
Difficulty wearing your lenses for your usual amount of time or new fogging that does not clear can signal deposit buildup or a change in lens fit. Contact our office if you notice any of these signs so we can evaluate and adjust your lenses as needed.
Certain symptoms require immediate attention to protect your vision. Call us right away if you experience any lens-related warning signs or general eye emergency symptoms.
Lens-related urgent symptoms include sudden vision decrease, severe pain that does not resolve after lens removal, heavy discharge or mucus, or intense redness that worsens or does not improve after removing lenses. If you suspect an infection or serious lens complication, do not wear your lenses again until our eye doctor examines you.
General eye emergency symptoms warrant urgent evaluation even if they are not related to your lenses. These include sudden vision loss, flashes of light, new floaters, or a curtain or shadow across your vision. Contact our office immediately if any of these occur.
Frequently Asked Questions
Insurance coverage for HERO lenses varies depending on your plan and the medical reason for the lenses. Many insurance plans cover scleral lenses when medically necessary for conditions like keratoconus or corneal disease, though you may have out-of-pocket costs. We can provide documentation to help you submit claims, and our staff will work with you to understand your benefits before you commit to the fitting process.
With excellent care, HERO lenses generally last between one and two years before protein deposits, scratches, or warping require replacement. Your wearing habits, tear chemistry, and how carefully you clean them all affect lens lifespan. We monitor your lenses at regular visits and recommend replacement when we see signs that lens quality is declining or when your prescription changes.
We do not recommend sleeping in HERO lenses for most patients, even though the material allows oxygen to reach your cornea. Overnight wear increases the risk of infections and complications that can threaten your vision. In very rare medical situations, our eye doctor may consider supervised overnight wear, but this is not standard practice.
Many new wearers struggle with insertion or removal at first, but nearly everyone succeeds with practice and coaching. You can schedule additional training appointments with our staff who will help you refine your technique. We have different tools and methods that work for different people, so we can find an approach that makes handling easier for you.
Yes, scleral lenses like HERO are safe for long-term use when you follow proper care routines and attend regular follow-up appointments. The lenses do not touch your cornea, which reduces the risk of corneal damage compared to some other lens types. Long-term studies of scleral lens wearers show good eye health outcomes when patients maintain good hygiene and comply with replacement schedules.
Contact our office right away if you lose or damage a lens, and we can order a replacement using your existing specifications. Most replacements arrive within two to four weeks, though expedited options may be available in urgent situations. We keep your lens parameters on file, so you do not need to repeat the entire fitting process unless your eyes have changed significantly.
