Living with keratoconus can feel overwhelming when your vision changes and traditional glasses or contacts no longer help. Everyday tasks like driving, reading, or recognizing faces may become frustrating. Fortunately, scleral lenses provide a safe and effective solution for many people living with keratoconus. These advanced lenses restore clear vision, protect the cornea, and bring back comfort, often delaying or even eliminating the need for corneal surgery.
What Is Keratoconus?
Keratoconus is a progressive eye condition where the normally round cornea becomes thin and bulges outward into a cone shape. This irregular curve distorts light as it enters the eye, leading to blurry, streaked, or doubled vision. The condition usually affects both eyes but can progress at different rates.
Common Symptoms Include
- Blurred or distorted vision
- Sensitivity to light or glare
- Difficulty driving at night
- Frequent changes in eyeglass prescriptions
- Eye strain or headaches
- Trouble wearing standard contact lenses
Keratoconus often starts during the teenage years and may worsen through your 30s or 40s. While the exact cause is unclear, genetics, frequent eye rubbing, allergies, and oxidative stress may all play a role.
How Scleral Lenses Help People Living with Keratoconus
When glasses and soft contacts can’t provide clear vision, scleral lenses become one of the best non-surgical treatments available.
How They Work
Scleral lenses are large, gas-permeable contact lenses that rest on the white part of the eye (the sclera) rather than directly on the cornea. They vault over the irregular cornea, creating a space filled with sterile saline solution. This fluid layer smooths out the optical surface, allowing light to enter the eye evenly and restoring sharp, stable vision.
Benefits of Scleral Lenses for Keratoconus
Clearer vision
They correct irregularities that glasses or regular contacts can’t.
Increased comfort
They don’t touch the sensitive cornea, reducing irritation.
Hydration and protection
The saline layer keeps the cornea moist and shields it from friction and dust.
Slower disease progression
By protecting the cornea, scleral lenses can reduce scarring and further damage.
Reversible and non-surgical
You can remove them anytime, unlike surgical options such as corneal transplants.
For many patients, scleral lenses make it possible to return to work, school, and normal activities without vision limitations.
Daily Life with Scleral Lenses
Living with keratoconus while wearing scleral lenses involves a few adjustments, but most users find them easy to manage after an initial learning period.
1. Putting Them On and Taking Them Off
Scleral lenses are filled with saline solution before insertion. This step ensures your cornea stays hydrated throughout the day. A small suction tool (plunger) is typically used for application and removal, and your eye specialist will teach you how to do this safely.
2. Cleaning and Care
Since scleral lenses are reusable, proper cleaning is essential. Use recommended cleaning solutions daily to remove debris and prevent infection. Always rinse them with preservative-free saline before reinserting.
3. Comfort and Adaptation
It may take a few days or weeks to adapt fully. Some patients notice mild awareness at first, but once you adjust, the comfort level is often higher than with traditional contacts.
4. Lifestyle Benefits
People living with keratoconus often say that scleral lenses help them regain confidence in activities they had stopped, such as driving at night, working long hours on computers, or participating in sports.
Long-Term Outlook and Success Rates
Studies show that over 75–90% of keratoconus patients achieve clear, comfortable vision with scleral lenses and can avoid or delay corneal transplant surgery.
These lenses not only restore sight but also protect the cornea from further thinning or scarring, improving long-term eye health.
With proper care, many users wear scleral lenses comfortably for years. Regular follow-up visits with your optometrist are key to maintaining lens performance and corneal health.
Emotional and Practical Tips for Living with Keratoconus
Living with a chronic eye condition can be emotionally draining. Here are a few tips to maintain both mental and visual well-being:
Stay Connected with a Specialist
Find an eye care professional experienced in keratoconus and scleral lens fittings. Regular visits help monitor corneal changes and ensure your lenses remain comfortable and effective.
Avoid Eye Rubbing
Rubbing your eyes can worsen keratoconus by weakening the corneal structure. If allergies make your eyes itchy, ask your doctor about antihistamine eye drops.
Practice Healthy Eye Habits
- Follow lens hygiene instructions carefully.
- Stay hydrated and take breaks from screens.
- Wear sunglasses outdoors to protect from UV damage.
Protect Your Mental Health
Living with fluctuating vision can be stressful. Consider joining support groups or talking to others with keratoconus. Sharing experiences can help you feel understood and supported.
When to Seek Further Treatment
Although scleral lenses work well for most patients, there are situations where additional treatments may be needed:
- When the corneal tissue is severely scarred or affected by hydrops, scleral lenses cannot fit properly.
- If the cornea becomes extremely thin or too steep, the lenses are unable to vault safely.
- Some patients also develop lens intolerance, experiencing constant discomfort or handling difficulties.
In such cases, your specialist may discuss corneal cross-linking (to stop disease progression) or corneal transplant surgery (to replace severely damaged tissue).
Book an Appointment
If you’re living with keratoconus and struggling with blurred or distorted vision, scleral lenses could be the key to seeing clearly again. Schedule a consultation with a keratoconus specialist to find out if scleral lenses are right for you.
Professional fitting ensures the best comfort, stability, and protection for your eyes — helping you live confidently with keratoconus every day.
Frequently Asked Questions
Can I sleep while wearing scleral lenses?
No. Scleral lenses should be removed before sleeping to allow the cornea to breathe and to prevent infections
How long can I wear scleral lenses each day?
Most users comfortably wear them for 10–14 hours daily. Your doctor will recommend what’s best for your eyes.
Are scleral lenses painful to wear?
Not at all, once you’re used to them. Since they rest on the sclera (a less sensitive part of the eye), they are usually more comfortable than smaller contact lenses.
How much do scleral lenses cost?
They are more expensive than standard lenses due to custom fitting, but they can last for 1–2 years with proper care. Many patients consider them worth the investment for restored vision and comfort.
Can scleral lenses cure keratoconus?
No, they don’t cure the disease, but they effectively manage vision and protect the cornea, often reducing the need for surgery.
