How Scleral Contact Lenses Improve Blurry Vision

Standard glasses and soft contact lenses work well for many prescriptions, but correcting vision can become more difficult when the cornea has an irregular shape. If your lenses shift, vision remains distorted, or contacts become uncomfortable after a short time, scleral contact lenses may provide another option.

Scleral lenses do not repair or permanently reshape an irregular cornea. Instead, their distinctive design creates a smoother optical surface that can improve how light enters the eye while the lenses are being worn.

Why Can an Irregular Cornea Cause Blurry Vision?

The cornea is the transparent front surface of the eye, and its shape helps focus light. When that surface is uneven, light may scatter rather than forming a precise image on the retina, leading to blur, glare, ghosting, or distorted vision.

Keratoconus is one reason a cornea may become irregular. Corneal scarring, previous surgery, injury, and other conditions can also affect its shape. Standard soft lenses conform closely to the cornea, so they may not fully compensate for significant irregularity.

How Do Scleral Contact Lenses Work?

Scleral lenses are larger rigid gas-permeable lenses that extend over the cornea and rest on the sclera, the white part of the eye. Because the lens holds its shape and vaults over the cornea, it can create a stable, regular surface for light to pass through.

The space between the lens and cornea is filled with preservative-free saline before insertion. This fluid reservoir helps bridge irregular areas while keeping the corneal surface bathed in fluid throughout wear.

Compared with a smaller corneal lens, the larger design may also provide greater stability and less movement. Results vary, but these features can make scleral lenses useful when conventional glasses or contact lenses do not provide satisfactory vision.

Who May Benefit From Specialty Contact Lenses?

Custom scleral contacts may be considered for people with:

• Keratoconus or another corneal ectasia
• An irregular corneal surface
• Corneal scarring or previous eye surgery
• High or irregular astigmatism
• Soft lenses that move or produce unstable vision
• Certain forms of significant ocular surface disease
• Persistent difficulty tolerating conventional contacts

Dry eye scleral lenses may help selected patients because the fluid reservoir remains between the lens and cornea. However, dry eye has many possible causes, and a scleral lens is not appropriate for everyone. A detailed evaluation is needed to determine whether it fits the patient’s eye health and daily needs.

What Happens During a Scleral Contact Lens Exam?

A scleral contact lens exam involves more than selecting a prescription. At Camelback Eye Care, the process begins with an evaluation of your vision, eye health, corneal shape, symptoms, and previous contact lens experience.

The practice uses Pentacam corneal imaging to create a detailed map of the cornea and help guide the lens design. During the contact lens fitting, trial lenses may be evaluated to assess:

• How the lens vaults over the cornea
• Where the lens rests on the sclera
• The amount and distribution of fluid beneath it
• Lens stability and comfort
• Visual performance with the lens in place

Custom scleral contacts often require adjustments and follow-up visits. Fine-tuning the design helps account for the unique shape of each eye rather than relying on a standard, one-size-fits-all lens.

Is Learning to Wear Scleral Lenses Difficult?

Scleral lenses require a different insertion method because the bowl of the lens must be filled with the recommended saline before it is placed on the eye. Patients also need to learn proper removal, cleaning, storage, and inspection techniques.

The team at Camelback Eye Care reviews these steps and provides hands-on guidance. Follow-up appointments allow the optometrist to monitor eye health, evaluate the fit, and adjust the lens or wearing schedule when necessary.

Never rinse or fill scleral lenses with tap water. Use only the products recommended by your eye doctor, and remove the lenses promptly if you develop pain, marked redness, discharge, light sensitivity, or a sudden change in vision.
