Are Scleral Lenses the Best Contact Lenses?
How Scleral Lenses Work
Scleral lenses use a custom design that rests on the white part of the eye instead of the cornea. This section reviews the key features that make them unique.
Scleral lenses are crafted from detailed scans of your eye. The exact match to your cornea and sclera keeps the lens stable and delivers crisp, reliable vision.
Because the lens does not touch the cornea, it avoids rubbing sensitive or irregular areas. This reduces irritation and light sensitivity for many wearers.
Before insertion, the lens is filled with sterile saline that forms a moist layer over the cornea all day. This constant hydration eases dryness, supports healing, and creates a smooth refractive surface.
With diameters of 15–20 millimeters, scleral lenses anchor securely on the eye. The broad surface keeps the lens centered during blinking and active movement, allowing long hours of comfortable wear.
Scleral Lenses Versus Other Contact Lens Options
Many patients wonder how scleral lenses stack up against soft or rigid gas-permeable lenses. The points below highlight the main differences.
Scleral lenses bypass the sensitive cornea, limiting friction and discomfort. Soft lenses can feel pleasant at first but may not correct severe irregularity or dryness as well.
The fluid reservoir smooths corneal irregularities and keeps vision steady. Traditional rigid lenses can shift with every blink, causing brief blur.
The sealed design shields the cornea from dust, smoke, and wind while the fluid layer keeps the surface hydrated.
Certain eye problems respond especially well to the scleral design.
- Keratoconus
- Irregular corneas from injury or surgery
- Chronic dry eye syndrome
- High astigmatism
Who Benefits Most from Scleral Lenses
Not everyone needs a scleral lens, but specific groups often see dramatic improvement.
Patients with keratoconus, post-surgery irregularities, or corneal scarring gain clearer vision because the lens vaults over uneven tissue.
- Keratoconus: restores smooth optics
- Uneven cornea after LASIK, PRK, or transplant
- Scarring from injury or infection
The fluid reservoir keeps eyes moist all day, easing burning, itching, and sensitivity.
- Continuous hydration
- Stable comfort for 12–16 hours
- Barrier against drying winds and air-conditioning
Very strong prescriptions and past failures with soft or rigid lenses often respond well to the stable, custom fit of scleral lenses.
- Sharper vision with high refractive errors
- Better retention during sports or physical work
Conditions such as Stevens-Johnson syndrome or graft-versus-host disease benefit from the protective fluid layer that reduces dryness and grittiness.
Scleral lenses protect the graft and provide clear vision while the eye heals.
Our Contact Lens Specialists
A successful scleral lens experience starts with a detailed examination and expert follow-up. Here is what our team provides.
We map the cornea and sclera, review eye health, and discuss lifestyle needs before recommending any lens.
Using advanced imaging, we design a lens that aligns precisely with each eye to maximize comfort and clarity.
Regular follow-ups ensure the lenses remain safe and effective, and adjustments are made as needed.
Scleral Lenses and Corneal Gas Permeable Lenses
Both lens types are rigid and allow oxygen flow, yet they differ in several important ways.
Scleral lenses land on the sclera, while gas-permeable lenses sit directly on the cornea. The scleral design reduces contact with sensitive tissue.
Scleral lenses stay centered, providing steady vision. Gas-permeable lenses can shift and cause momentary blur.
The fluid reservoir and larger size of a scleral lens guard the cornea against dust and dryness better than a gas-permeable lens.
Scleral lenses may take longer to master because of their size, but many patients find the long-term comfort worth the learning curve.
Is a Scleral Lens the Best Choice?
Scleral lenses are unmatched for certain needs, yet they are not the answer for everyone. This section helps weigh the pros and cons.
For those with corneal irregularity, severe dryness, or high prescriptions, scleral lenses often provide the best comfort and clarity available.
Patients seeking the convenience of daily disposables or children needing myopia-controlling lenses might prefer other options recommended by the doctor.
Frequently Asked Questions
The questions below address common concerns about scleral lenses.
They are most often used to correct irregular corneas such as keratoconus or post-surgical changes. The fluid cushion also helps severe dry eye.
We fit them for keratoconus, corneal ectasia, irregular astigmatism, post-surgical corneal changes, severe dry eye, Sjögren's syndrome, and high refractive errors.
Most motivated patients can adapt to scleral lenses. Good candidates include people with irregular corneas, dry eye, strong prescriptions, or past lens intolerance.
Yes. Normal tears will not dislodge the lens, but avoid rubbing your eyes. Gently dab away tears instead.
Scleral lenses are safe when properly fitted, cleaned, and worn as directed. They allow oxygen to reach the eye and reduce corneal contact.
Most patients reach 12–16 hours of wear per day after a short adaptation period. Always remove the lenses if you feel discomfort.
