Keratoconus Treatment Options
Understanding Keratoconus
Your cornea is the clear, dome-shaped front surface of your eye that helps focus light. In keratoconus, the cornea becomes thinner and weaker over time, causing it to bulge forward into an irregular cone shape instead of maintaining its normal rounded curve.
This bulging creates an uneven surface that scatters light rays as they enter your eye. As a result, you may experience blurred vision, distortion, and increased sensitivity to glare and bright lights.
Keratoconus often develops slowly during your teenage years or early twenties. Early symptoms can be subtle and easy to miss at first.
- Blurry or distorted vision that gets worse over time
- Increased sensitivity to bright lights and glare
- Frequent changes in your eyeglass or contact lens prescription
- Seeing multiple images or ghost images from one eye
- Difficulty driving at night due to halos around lights
Certain factors can increase your chances of developing keratoconus. Understanding your risk helps us catch the condition early when treatment works best.
- Having a family history of keratoconus or other family members with the condition
- Chronic eye rubbing, especially vigorous or frequent rubbing
- Having atopic eye disease such as allergic conjunctivitis or vernal keratoconjunctivitis, and systemic atopy such as eczema or asthma
- Certain genetic conditions including Down syndrome and Ehlers-Danlos syndrome
- Being between the ages of 10 and 25 when the condition typically begins
Rubbing your eyes might seem harmless, but it can actually damage the delicate structure of your cornea over time. The physical pressure and repeated trauma from eye rubbing may weaken corneal tissue and contribute to the development or worsening of keratoconus.
Many people with allergies rub their eyes frequently to relieve itching and discomfort. If you have allergies, we can help you manage your symptoms with proper allergy treatments so you can avoid the urge to rub your eyes.
You should schedule an eye exam if you notice any sudden changes in your vision or if blurriness does not improve with your current glasses or contact lenses. Early detection makes a significant difference in treatment outcomes.
We also recommend regular eye exams if you have risk factors for keratoconus, even if you do not notice symptoms yet. Catching the condition in its early stages gives us more treatment options to preserve your vision.
How We Diagnose Keratoconus
During your eye exam, we will review your medical and family history and ask about your symptoms. We will then perform a series of tests to evaluate the shape, thickness, and overall health of your cornea.
A complete keratoconus evaluation typically includes vision testing, refraction measurements to determine your prescription, and specialized imaging of your corneal structure. These tests work together to give us a detailed picture of your eye health.
Corneal topography is a painless imaging test that creates a detailed three-dimensional map of your corneal surface. This technology measures thousands of points across your cornea to detect even subtle irregularities in its shape. Topography maps the front surface of the cornea, while more advanced tomography systems evaluate both front and back surfaces as well as thickness across the entire cornea.
The color-coded map shows us exactly where your cornea is steeper or flatter than normal. This information helps us diagnose keratoconus, monitor how it changes over time, and plan the best treatment approach for your specific case.
Corneal tomography using Scheimpflug imaging or anterior segment optical coherence tomography measures both the anterior and posterior corneal surfaces and generates detailed pachymetry maps. This advanced technology is central to early keratoconus detection in 2025 because it reveals subtle changes in the back surface of the cornea and corneal thickness distribution that topography alone may miss.
Epithelial thickness mapping can unmask very early keratoconus by showing focal epithelial thinning over the area of the cone. Because recent contact lens wear can distort these measurements, we may ask you to take a break from wearing your lenses for a period before your imaging appointment.
Pachymetry is a quick, comfortable test that measures how thick your cornea is at different points. We usually measure thickness using non-contact imaging. In some cases we use a small ultrasound probe after numbing the eye.
In keratoconus, we typically find that your cornea is thinner than normal, especially in the areas where it bulges outward. These thickness measurements help us determine the severity of your condition and track any progression.
Knowing whether your keratoconus is stable or getting worse is essential for deciding when to recommend treatments like corneal cross-linking. We use objective criteria to identify progression.
- Increase in maximum keratometry, or Kmax, by about 1.0 diopter or more over 6 to 12 months
- Increase in manifest cylinder or spherical equivalent not explained by measurement variability
- Thinning on pachymetry or tomography, or increasing posterior elevation
- Worsening best-corrected or uncorrected vision not due to other causes
A slit lamp is a specialized microscope that lets us examine the structures of your eye under high magnification. During this exam, we look for specific signs of keratoconus in your cornea.
- Fleischer ring, which is a golden-brown or greenish ring around the cone
- Vogt striae, which appear as fine vertical stress lines in the cornea
- Corneal scarring in more advanced cases
- Thinning of the corneal tissue
Non-Surgical Treatment Options for Keratoconus
If you have very mild keratoconus with minimal corneal irregularity, regular eyeglasses may provide adequate vision correction. Standard prescription lenses can often compensate for the refractive error caused by early corneal changes.
However, as keratoconus progresses and your cornea becomes more irregular, eyeglasses typically become less effective. At that point, we will recommend specialty contact lenses that work better with the altered shape of your cornea.
Specially designed soft contact lenses made for keratoconus may work well if your condition is still in the early stages. These are custom designs, not standard soft lenses, and can conform to the irregular shape of your cornea better than eyeglasses to provide clearer vision.
As your condition advances, you will likely need to transition to more specialized rigid or scleral lens options for optimal vision correction. Many patients progress to these more advanced lens designs as keratoconus develops.
Rigid gas permeable lenses, also called RGP or hard lenses, are a mainstay for correcting vision in keratoconus. These firm lenses hold their shape on your eye, creating a smooth optical surface that helps light focus properly on your retina.
The space between the rigid lens and your irregular cornea fills with tears, which helps neutralize the corneal distortion. While RGP lenses may take some time to get used to, most patients adapt well and enjoy significantly improved vision. For moderate to severe keratoconus, scleral lenses are often preferred for comfort, stability, and optical quality.
Scleral lenses are larger diameter rigid lenses that vault over your entire cornea and rest on the white part of your eye called the sclera. These lenses work exceptionally well for advanced keratoconus and irregular corneas that other lenses cannot fit properly.
- They provide excellent comfort because they do not touch the sensitive corneal cone
- The large fluid reservoir between the lens and cornea keeps your eye moist and comfortable
- They offer stable, clear vision even with severe corneal irregularity
- Many patients find them comfortable once trained, though insertion and removal take practice
Proper care and handling are essential for successful scleral lens wear.
- Fill the lens with preservative-free sterile saline only. Never use tap water
- Learn proper insertion and removal to avoid bubbles that blur vision
- Clean and disinfect with the solutions we recommend. A peroxide-based system is often used for disinfection
- Do not sleep in scleral lenses unless we have explicitly prescribed extended wear
- Midday fogging can occur. We will review strategies to reduce it
Hybrid contact lenses combine a rigid gas permeable center with a soft lens skirt around the edge. This design gives you the clear vision of a rigid lens with comfort similar to soft lenses.
The rigid center corrects the irregular corneal shape, while the soft outer ring helps the lens stay centered and comfortable on your eye. These lenses can be a good option if you have not tolerated traditional rigid lenses well.
Corneal Cross-Linking and Reshaping Procedures
Corneal cross-linking is a procedure designed to strengthen your cornea and halt the progression of keratoconus. During this treatment, we apply riboflavin eye drops to your cornea and then activate them with ultraviolet light.
This process creates new bonds between collagen fibers in your cornea, making the tissue stronger and more stable. Cross-linking is considered the standard of care in 2025 for progressive keratoconus and has been shown to effectively stop or slow worsening in most patients. We typically recommend this treatment if we detect that your keratoconus is getting worse.
Cross-linking recovery and risks include several important considerations.
- Most treatments are performed with the epithelium removed, called epi-off cross-linking
- Expect discomfort, tearing, and light sensitivity for several days. Vision is often blurry for 1 to 2 weeks as the surface heals
- Temporary corneal haze can occur. Rare risks include infection, delayed epithelial healing, sterile infiltrates, and scarring
- The goal is to stop progression. Vision may or may not improve
- We use antibiotic and steroid eye drops and a bandage contact lens during early healing
The cornea must meet minimum thickness criteria before we can safely perform cross-linking. We avoid this procedure if you have active infection or severe scarring, and we use caution in pregnancy and autoimmune disease. You will need sunglasses outdoors and must avoid eye rubbing during healing. Contact lenses may need refitting several weeks to months after treatment.
Intracorneal ring segments, or ICRS, are tiny curved plastic inserts that we surgically place in your cornea to help flatten the cone and improve its shape. These semi-circular segments work by redistributing pressure and reshaping the corneal curvature.
This procedure may improve your vision and make it easier to fit contact lenses successfully. ICRS may be considered in specific cases where corneal shape significantly affects lens fitting or vision quality, though their use has become less common as other treatments have advanced.
Limitations and risks of ICRS are important to understand.
- ICRS do not halt progression and are often combined with cross-linking
- Glare and halos can occur, especially at night
- Segments can shift position or rarely extrude and may need removal
- Infection and scarring are uncommon but possible
- Results vary based on cone location and corneal thickness
Some centers use customized superficial laser surface reshaping with concurrent corneal cross-linking in carefully selected eyes with adequate corneal thickness. This approach uses detailed topography maps to guide a very precise, shallow laser treatment on the corneal surface.
The goals are improved corneal shape and optical quality, not guaranteed independence from glasses or contact lenses. Candidate selection is critical, and not all patients are appropriate for this combined procedure. We evaluate thickness, progression status, and other factors before considering this option.
We often recommend combining different treatments to achieve the best possible results for your vision and eye health. The most common approach is to perform corneal cross-linking to stop progression while also fitting you with specialty contact lenses to optimize your vision.
In some situations, we may combine cross-linking with other procedures or use multiple types of contact lenses over time as your needs change. Your personalized treatment plan depends on the severity of your keratoconus, how fast it is progressing, and your vision goals.
Implantable Lenses and Corneal Transplant Options
In select patients with stable corneas after cross-linking, phakic implantable collamer lenses, or ICLs, can reduce myopia and astigmatism without removing corneal tissue. An ICL is a tiny lens placed inside your eye, in front of your natural lens, similar to a permanent contact lens.
ICLs do not correct irregular astigmatism caused by the cone shape, so glasses or specialty contact lenses may still be needed for your best vision. Typical risks include glare and halos, elevated eye pressure, and cataract risk over time. This option is reserved for carefully selected cases.
Deep anterior lamellar keratoplasty, or DALK, is a partial corneal transplant procedure where we replace the diseased front layers of your cornea while keeping your own healthy inner layer. This approach preserves your natural endothelial cells, which are important for maintaining corneal clarity.
DALK may be recommended if your keratoconus is advanced and you cannot achieve adequate vision with contact lenses, but your inner corneal layer remains healthy. This procedure generally has a lower risk of rejection compared to full-thickness transplants.
Risks and recovery considerations for DALK include the following.
- Intraoperative perforation can necessitate conversion to full-thickness transplant
- Rejection risk is lower than with full-thickness grafts but still possible
- Suture removal typically occurs over 6 to 18 months, and residual astigmatism may require glasses or specialty lenses
- Steroid drop therapy and regular monitoring are required
Penetrating keratoplasty, or a full-thickness corneal transplant, involves replacing your entire cornea with healthy donor tissue. We may recommend this procedure if you have severe keratoconus with scarring that involves all layers of the cornea.
While this is the most invasive option, corneal transplants have high success rates for keratoconus patients. Recovery takes several months, and you will need careful follow-up care. Many patients achieve improved vision after healing, though you may still need glasses or contact lenses for the best results.
Risks and aftercare for penetrating keratoplasty are extensive.
- Long-term steroid eye drops and frequent follow-ups are needed
- Graft rejection can occur. Watch for redness, light sensitivity, vision decrease, and pain, and call urgently if these appear
- High astigmatism is common. Glasses, rigid, or scleral lenses may be needed
- The wound remains vulnerable to blunt trauma. Use protective eyewear for high-risk activities
Living with Keratoconus and Follow-Up Care
One of the most important things you can do is avoid rubbing your eyes, no matter how itchy or irritated they feel. If you experience eye discomfort, talk to us about safe ways to find relief without rubbing.
- Manage allergies with appropriate medications to reduce itching
- Use preservative-free artificial tears to soothe dry or irritated eyes
- Wear protective eyewear during sports and activities that could injure your eyes
- Follow your treatment plan consistently and attend all scheduled appointments
Proper care of your contact lenses is essential for clear vision, comfort, and eye health. Always wash and dry your hands thoroughly before handling your lenses, and use only the cleaning solutions that we recommend for your specific lens type.
Clean and disinfect your lenses exactly as instructed, and replace your lens case regularly to prevent bacterial buildup. Never sleep in your lenses unless we have specifically prescribed extended-wear lenses, and replace your lenses according to the recommended schedule.
Water exposure and contamination are serious risks for contact lens wearers.
- Never expose lenses or cases to tap water. Do not shower, swim, or use hot tubs while wearing contact lenses
- For scleral lenses, fill the bowl with preservative-free sterile saline, not multipurpose solution
- Use a peroxide-based disinfection system if recommended and replace lens cases every 1 to 3 months
Regular monitoring is crucial because keratoconus can change over time, especially in younger patients. In the beginning, we typically see you every three to six months to check for any progression and ensure your treatment is working well.
If your condition is stable and well-controlled, we may extend the time between visits to once a year. However, the exact schedule depends on your age, how active your keratoconus is, and which treatments you are using. Typical post-cross-linking visits occur at 1 day, 1 week, 1 to 3 months, then 6 to 12 months. After keratoplasty, expect frequent visits early and suture management over the first year or longer.
Pediatric keratoconus can progress more rapidly than in adults and often merits earlier intervention with corneal cross-linking to prevent severe vision loss. If your child is diagnosed with keratoconus, we will monitor closely and may recommend more aggressive treatment to stabilize the cornea during the critical growth years.
Hormonal changes during pregnancy can temporarily worsen keratoconus in some women, so more frequent monitoring is recommended if you are pregnant or planning pregnancy. We balance treatment decisions carefully during pregnancy, as some interventions are deferred until after delivery.
Most changes in keratoconus happen gradually, but certain symptoms require urgent attention. Contact our office right away if you experience sudden vision loss, severe eye pain, or significant changes in vision that happen over a short period.
You should also seek immediate care if you notice sudden clouding of your cornea, which could indicate corneal hydrops where fluid enters the cornea. Severe redness, discharge, or pain while wearing contact lenses may signal an infection that needs prompt treatment. If you wear contact lenses and develop a red, painful eye or decreased vision, remove the lens immediately and do not reinsert it until you are examined.
Frequently Asked Questions About Keratoconus
Keratoconus cannot be completely cured, but it can be effectively managed and controlled with modern treatments. Corneal cross-linking can halt progression in most cases, and specialty contact lenses or surgical procedures can restore clear, functional vision for the vast majority of patients.
The key is early detection and appropriate treatment tailored to your individual needs. With the treatment options available in 2025, most people with keratoconus maintain good vision and quality of life.
Keratoconus typically progresses most rapidly during your teens and twenties, then often stabilizes on its own as you get older. However, with corneal cross-linking now available, we can usually stop or significantly slow progression before significant vision loss occurs, particularly if we catch it early.
Regular monitoring allows us to detect any changes and intervene promptly if your condition shows signs of worsening. Not all cases progress at the same rate, and some remain stable without treatment.
Keratoconus does have a genetic component, and children of affected parents have a higher risk of developing the condition than the general population. We recommend that your children have regular comprehensive eye exams starting in childhood so we can detect any signs early and provide treatment if needed.
Early screening is especially important during the teenage years when keratoconus often first appears. If detected early, we have excellent options to stabilize the condition and preserve vision.
We determine the best treatment based on several factors including how severe your keratoconus is, whether it is currently progressing, your age, and your vision needs. During your appointment, we will discuss your test results and explain which options match your specific situation and goals.
Treatment is highly individualized, and what works best for one patient may differ for another. We will work with you to develop a plan that addresses both your current vision and long-term eye health.
Frequently Asked Questions About Treatment and Costs
LASIK surgery thins and weakens the cornea, which would make keratoconus much worse and potentially cause serious complications. Because the cornea in keratoconus is already weak and thin, any procedure that removes corneal tissue is unsafe and could lead to severe vision problems.
In fact, undetected mild keratoconus is considered a major contraindication to LASIK, which is why thorough screening with corneal topography and tomography is essential before any laser vision correction procedure.
Most patients experience discomfort, tearing, and light sensitivity for several days after epi-off cross-linking. Vision is often blurry for 1 to 2 weeks as the corneal surface heals. We prescribe antibiotic and steroid eye drops and place a bandage contact lens to aid healing.
You will need to protect your eyes from bright light and avoid rubbing during recovery. Most people can return to normal activities within a few days, though complete visual recovery may take several weeks to months.
Yes, contact lens refitting is often needed after cross-linking and timing typically ranges from several weeks to a few months once the cornea stabilizes and heals. We will monitor your corneal shape and surface health to determine the right time to refit your lenses for optimal comfort and vision.
In many cases, cross-linking improves the corneal shape slightly, which can make contact lens fitting easier or improve the fit of your existing lenses. We will guide you through the refitting process when you are ready.
Coverage varies by insurance plan and depends on medical necessity. Many plans cover corneal cross-linking and specialty contact lenses for keratoconus, but prior authorization and documentation are often required.
Our staff can help you navigate the authorization process and verify your benefits. We will provide the medical records and testing results needed to support your coverage request.
