What Is It Like to Wear Scleral Lenses With Advanced Keratoconus?

Living with advanced keratoconus can make everyday vision tasks feel frustrating and limiting. As the cornea becomes increasingly irregular, traditional glasses and even standard contact lenses often fail to provide clear or comfortable vision. For many patients with advanced keratoconus, scleral lenses offer a life-changing solution.

Why Standard Lenses Often Fail in Advanced Keratoconus

In advanced keratoconus, the cornea thins and bulges into a cone-like shape, creating significant visual distortion. This irregular surface makes it difficult for glasses or soft contact lenses to correct vision effectively. Even traditional rigid gas permeable (RGP) lenses can become uncomfortable or unstable as the corneal shape worsens.

How Scleral Lenses Work for Advanced Keratoconus

Unlike standard contact lenses, scleral lenses are larger in diameter and rest on the white part of the eye (the sclera), vaulting completely over the cornea. This design creates a smooth optical surface by trapping a layer of fluid between the lens and the eye.

For patients with advanced keratoconus, this fluid reservoir:

• Neutralizes corneal irregularities

• Dramatically improves visual clarity

• Reduces glare, halos, and ghosting

• Protects sensitive or scarred corneal tissue

What Vision Feels Like With Scleral Lenses

Many patients describe the visual improvement as dramatic - sometimes immediate.

Common experiences include:

• Sharper, more stable vision throughout the day

• Improved depth perception

• Reduced visual distortion and double vision

• Greater confidence driving, reading, and using digital screens

For individuals who struggled to function visually with glasses or other contacts, scleral lenses can feel like regaining usable vision again.

Comfort: What Surprises Most Patients

Despite being larger than traditional contacts, scleral lenses are often more comfortable, especially for advanced keratoconus patients.

Because they don’t touch the sensitive corneal surface, many wearers report:

• Little to no lens awareness once inserted

• Less irritation compared to smaller hard lenses

• Increased comfort even during long wear times

Most patients adapt quickly, often within the first few weeks.

Daily Wear and Care Expectations

Scleral lenses do require a bit more care than standard contacts, but most patients find the routine manageable with proper training.

Typical expectations include:

• Filling lenses with sterile saline before insertion

• Learning specific insertion and removal techniques

• Cleaning and disinfecting lenses daily

With experience, the process becomes second nature.
