Scleral Lenses vs. Standard Contacts for Keratoconus: A Clark County Specialist Guide

Keratoconus changes the shape of the cornea, causing it to become thinner and more cone-shaped instead of maintaining a smooth, rounded surface. As the cornea becomes irregular, standard glasses or soft contact lenses may no longer provide the clear, stable vision you need.
 

For patients in Vancouver and throughout Clark County, understanding how scleral lenses differ from standard contacts can make it easier to discuss the right vision correction options with your eye doctor.
 

Why Is Keratoconus Harder to Correct?

A regular corneal surface helps focus light precisely onto the retina. With keratoconus, the irregular corneal shape can create distorted or fluctuating vision that is difficult to correct with a standard prescription alone.
 

Some people with mild keratoconus can still achieve useful vision with glasses or conventional soft contacts. As the condition progresses, however, more customized contact lens designs may be needed to improve visual clarity.
 

How Do Standard Soft Contacts Work?

Standard soft contact lenses drape closely over the cornea. They work well for many common prescriptions, including nearsightedness, farsightedness, and astigmatism.
 

For keratoconus, standard soft lenses may become less effective when the corneal surface is highly irregular because the flexible lens tends to follow the shape underneath it.
 

Signs that a standard contact lens may no longer be meeting your needs include:
 

• Vision that remains blurry despite an updated prescription

• Frequent changes in visual clarity

• Difficulty seeing clearly at night

• Lenses that move or feel unstable

• Persistent discomfort with your current contacts
   

These symptoms deserve a contact lens evaluation rather than simply increasing the prescription strength.
 

How Are Scleral Lenses Different?

Scleral lenses are larger rigid gas permeable lenses designed to vault over the cornea and rest on the white portion of the eye, called the sclera. Before insertion, the space beneath the lens is filled with sterile preservative-free saline.
 

Because the lens creates a smooth optical surface over the irregular cornea, scleral lenses can provide sharper, more stable vision for some people with keratoconus. The fluid reservoir beneath the lens may also help protect the corneal surface during wear.
 

Scleral lenses require careful fitting, handling, cleaning, and follow-up. They are not automatically the best choice for every person with keratoconus.
 

What About RGP and Other Custom Lenses?

Scleral lenses are only one specialty contact lens option. Smaller rigid gas permeable lenses can also create a more regular optical surface and may provide excellent vision for some keratoconus patients.
 

At Westside Eye Center, we offer customized contact lens fittings and RGP lenses based on each patient's corneal shape, tear film, prescription, and lifestyle. A detailed fitting helps determine which lens design provides an appropriate combination of clarity, comfort, and eye health.
 

Which Contact Lens Is Right for You?

The best lens depends on the severity and shape of your keratoconus, your previous experience with contacts, your tear film, and your visual needs.
 

Contact lenses improve vision but do not stop keratoconus from progressing. If changes in corneal shape are occurring, your eye doctor may recommend additional monitoring or referral for treatments such as corneal cross-linking, which is intended to help stabilize the cornea.
 

Regular eye examinations are especially important because keratoconus can change over time.
