Scleral Contact Lenses

Scleral lenses are discussed when wearers need more than a standard soft contact lens fit.

• Keratoconus or other corneal shape changes.
• Irregular corneas after surgery, injury, or disease.
• Severe dry eye or ocular surface disease.
• High astigmatism or vision that is not clear enough with glasses or standard contacts.

Keratoconus can make the cornea thinner and more cone-shaped, which may cause distorted or unstable vision. Scleral lenses can vault over the irregular cornea instead of pressing directly on it.

The lens and fluid layer can create a smoother front surface for focusing light. This is one reason eye doctors may compare scleral lenses with smaller rigid gas permeable lenses, hybrid lenses, or glasses for keratoconus.

Before ordering, confirm that your scleral lens prescription is final after your fitting and follow-up visit. Trial lens measurements and final order details may not be the same.

Fluid-Filled Design

Scleral lenses are filled with sterile preservative-free saline before they are placed on the eye. This fluid layer sits between the lens and the cornea during wear.

Surface Protection

The lens vaults over the cornea and rests on the sclera. This design may reduce direct contact with the sensitive corneal surface for some wearers.

Care and Wear Time

Dry eye comfort still depends on fit, filling solution, wearing time, tear film, and cleaning routine. If your lenses fog, feel tight, or become uncomfortable during the day, ask your eye doctor to check the fit and care routine.

You should not sleep in scleral contact lenses unless your eye doctor specifically prescribed that schedule for your exact lenses. Most scleral lens wear routines are daytime wear with removal, cleaning, and disinfection after use. Sleeping in contacts that are not approved for overnight wear can raise the chance of irritation, infection, or reduced oxygen to the eye. If you accidentally sleep in your scleral lenses and notice pain, redness, light sensitivity, or blurry vision, remove them if you can and contact your eye doctor.

Scleral lenses need daily cleaning and disinfection because deposits and poor storage can affect comfort, vision, and eye health.

Step 1. Clean after removal.

Place the lens in your palm and clean it with the product your eye doctor recommended. Follow the label instructions for rubbing or handling.

Step 2. Rinse only as directed.

Use the approved rinsing product for your lens system. Do not use tap water or saliva.

Step 3. Disinfect before storage.

Store lenses in fresh disinfecting solution for the full time listed on the product label. Never top off the old solution left in the case.

Step 4. Use fresh filling solution before wear.

Disinfecting solution is not always the same as filling solution. Use the preservative-free saline or filling product approved for insertion.

Step 5. Replace the case and check the lens.

Keep the case clean and replace it as directed. Do not wear a lens that is cracked, chipped, scratched, cloudy, or painful.

Foggy vision with scleral lenses can happen during wear, even when the lens looks clear at insertion. Midday fogging often involves debris or particles collecting in the fluid reservoir between the lens and the eye surface.

• Reservoir debris can make vision look hazy after a few hours of wear.
• Poor lens wetting can create blur on the front surface of the lens.
• Air bubbles under the lens can distort vision and cause discomfort.
• Lens deposits may build up when cleaning or rinsing is not thorough enough.
• Fit changes can affect how the lens holds fluid and sits on the eye.

Scleral contact lens replacement depends on lens condition, prescription changes, wearing habits, and your eye doctor's instructions.

1. Lens condition

Replace the lens if it becomes scratched, warped, chipped, cracked, cloudy, or uncomfortable. Damage can affect both vision and eye comfort.

2. Prescription and fit changes

A lens may need replacement if your prescription, corneal shape, tear film, or ocular surface condition changes. Follow-up visits help confirm whether the lens still fits properly.

3. Care routine

Proper cleaning, disinfection, storage, and case hygiene can help protect the lens. Poor care can shorten lens life and raise the risk of eye irritation.

Scleral lenses are filled with sterile preservative-free saline before insertion. The filling solution sits against the eye surface during wear, so it should be the product your eye doctor approved for your lenses.

Good match if:

• The product is labeled for scleral lens filling or insertion.
• It is sterile and preservative-free.
• It comes in single-use vials or another format your eye doctor approves.
• Your eye doctor confirms it works with your lens material and eye surface needs.

Recheck before using if:

• The bottle is a multipurpose soft lens solution.
• The saline contains preservatives.
• The product is expired or has been open longer than allowed.
• You are unsure whether it is for filling, rinsing, cleaning, or disinfection.

Corneal Rigid Gas Permeable Lenses

Corneal RGP lenses are smaller rigid lenses that sit on the cornea. They can give sharp vision for some prescriptions but may feel more noticeable for wearers who are sensitive to corneal lens movement.

Scleral Contact Lenses

Scleral lenses are larger GP lenses that vault over the cornea and rest on the sclera. Their larger diameter and fluid reservoir can make them useful for some irregular corneas or dry eye needs.

Which Lens to Discuss

The better option depends on your corneal shape, tear film, prescription, comfort, and fitting results. Your eye doctor may compare corneal RGP, scleral, hybrid, or soft lens designs before finalizing your prescription.
