What Are Scleral Lenses?

What Are Scleral Lenses?

Scleral lenses are custom-made to match the unique shape of each eye, providing stable, high-quality vision and relief from discomfort that smaller lenses may cause.

The lens forms a dome over the cornea, leaving a reservoir of sterile saline between the lens and the eye. This liquid layer masks surface irregularities and keeps the cornea continuously hydrated, resulting in crisp vision and lasting comfort.

Because they bypass irregular corneal surfaces, scleral lenses are often prescribed for a variety of medical and vision needs.

  • Keratoconus
  • Astigmatism
  • Dry eye disease
  • Giant papillary conjunctivitis
  • Post-refractive surgery, such as LASIK or PRK
  • Presbyopia, myopia, or hyperopia
  • After corneal transplant
  • Other corneal irregularities

Patients often find scleral lenses more dependable and soothing than traditional soft or smaller rigid lenses.

  • Large diameter helps the lens stay centered and stable
  • Durable, high-quality materials extend lens life
  • Shield the eye from dust, debris, and allergens
  • Gas-permeable design allows ample oxygen to reach the cornea
  • Fluid cushion keeps the eye moist and comfortable

Scleral Lenses for Keratoconus


Keratoconus is one of the most common conditions managed with scleral lenses because the lenses create a smooth optical surface over a cone-shaped cornea.

Keratoconus occurs when the cornea progressively thins and bulges forward into a cone or football shape. This distortion disrupts normal refraction and can significantly blur vision.

Patients may notice gradual or sudden changes in vision quality.

  • Blurred or distorted vision
  • Sudden worsening or clouding of vision
  • Increased sensitivity to light and glare

The vaulted design of a scleral lens creates a smooth, dome-like front surface that compensates for the cornea’s uneven shape, restoring clear focus and reducing visual distortions.

Getting Fitted for Scleral Lenses

A detailed evaluation and fitting process ensures each lens provides optimal clarity and comfort.

During the initial visit, the doctor reviews ocular history, examines the cornea, and determines whether scleral lenses are the best option for vision and eye health.

Specialized imaging and diagnostic lenses allow precise measurements of corneal and scleral shape. These data guide the creation of custom lenses made to each patient’s specifications.

Once lenses are dispensed, patients receive training on insertion, removal, and care. A personalized lens can be life-changing, offering stable vision and lasting comfort throughout daily activities.

Inserting and Removing Scleral Lenses

Inserting and Removing Scleral Lenses

Proper handling techniques protect eye health and extend lens life.

Follow these basic steps each time you put your lenses in.

  • Wash hands with mild soap and dry with a lint-free towel.
  • Inspect the lens for debris, cracks, or cloudy deposits.
  • Fill the bowl of the lens completely with preservative-free saline.
  • With fingers or an inserter tool, gently place the lens on the eye until the saline touches the cornea.
  • Blink slowly to allow the lens to settle, then repeat with the other eye.

Small adjustments can make application easier and cleaner.

  • Hold eyelashes out of the way and keep eyelids taut.
  • Place a soft towel on the countertop to catch a dropped lens.
  • Remain still while searching for a fallen lens to avoid stepping on it.

Lenses can be removed with either a suction plunger or fingertips. With a plunger, moisten the tip with saline, attach it to the lower third of the lens, and lift gently away from the eye. To remove by hand, place fingertips on opposite edges of the lens, press lightly to release the seal, and catch the lens as it pops out.

Frequently Asked Questions


Below are answers to common questions about scleral lenses and everyday wear.

The lens is filled with sterile saline before insertion, creating a constantly hydrated environment that protects the cornea from dryness, irritation, and redness while delivering sharp vision.

Each lens is custom-fit to the exact shape of the eye, providing stable positioning and reducing friction. The large diameter also keeps the lens from moving or falling out during active tasks.

Most patients adapt within about two weeks. Gradually increasing daily wear time, using plenty of saline during insertion, and following cleaning instructions closely help speed the adjustment period.
