Scleral Lenses: What They Are, How They Work, and Why They’re Life-Changing

Introduction: A New Era in Vision Correction

When traditional glasses or contact lenses fail, the world can feel blurry—literally and figuratively. This is a reality for many individuals with conditions like keratoconus, dry eye syndrome, or post-surgical complications. These challenges demand more than a one-size-fits-all solution. At Global Vision Rehabilitation Center, led by Dr. Edward Boshnick, we’re pioneering solutions that go beyond traditional methods, with scleral lenses leading the way.

As one of the foremost experts in specialty eye care, Dr. Boshnick has helped thousands of patients regain their vision and confidence. By combining his extensive expertise with cutting-edge technology like the WaveDyn Vision Analyzer, our practice is transforming lives—one lens at a time.


What Are Scleral Lenses?

Scleral lenses are more than just a type of contact lens—they’re a breakthrough for individuals with complex eye conditions. Unlike conventional lenses that rest on the cornea, scleral lenses vault over the cornea and sit on the sclera (the white part of the eye). This unique design creates a tear-filled reservoir that hydrates, protects, and stabilizes the eye while offering sharper, more comfortable vision.


Key Features of Scleral Lenses

  1. Hydration Like No Other
    Imagine having a tiny pool of saline solution between your lens and eye all day. That’s exactly what scleral lenses provide—a continuous source of hydration that soothes irritation caused by dry eye syndrome or meibomian gland dysfunction.

  2. Enhanced Comfort
    Traditional lenses can rub against the cornea, causing discomfort and even pain. Scleral lenses bypass this by resting entirely on the sclera, making them ideal for sensitive eyes.

  3. Stable Vision Correction
    Whether you’re battling distortions from keratoconus or irregularities after LASIK, scleral lenses create a smooth optical surface, delivering sharp and consistent vision.

  4. Protection for the Cornea
    The tear-filled vault acts as a shield, protecting the cornea from environmental irritants and further damage—a lifesaver for patients with corneal ectasia or similar conditions.


Dr. Edward Boshnick: The Visionary Behind the Solutions

How Do Scleral Lenses Work?

Understanding how scleral lenses work requires a closer look at their unique design.

1. Vaulting Over the Cornea

Unlike standard lenses, scleral lenses never touch the cornea directly. Instead, they vault over it, leaving space for a reservoir of saline solution. This ensures that the sensitive corneal surface is protected and hydrated throughout the day.

2. Resting on the Sclera

By sitting on the sclera—the less sensitive white part of the eye—these lenses distribute pressure more evenly, reducing irritation and enhancing comfort.

3. Correcting Irregularities

Conditions like keratoconus cause the cornea to bulge into an irregular shape, distorting vision. Scleral lenses create a smooth optical surface that corrects these irregularities, providing sharp and stable vision.


Technology That Makes the Difference

At Global Vision Rehabilitation Center, we pair scleral lenses with advanced diagnostic tools to ensure a perfect fit.

WaveDyn Vision Analyzer: This cutting-edge tool captures dynamic, real-time data about the eye’s optical system, enabling precise lens design.

Who Can Benefit from Scleral Lenses?

Scleral lenses aren’t just a one-size-fits-all solution—they’re a personalized approach to tackling some of the most challenging eye conditions. At Global Vision Rehabilitation Center, led by Dr. Edward Boshnick, we’ve seen firsthand how these lenses transform lives by providing relief, clarity, and comfort to patients with complex eye conditions.

Let’s explore how scleral lenses can benefit individuals with specific conditions and why they are considered a game-changer in modern vision care.


1. Keratoconus: Stabilizing Vision and Comfort

Keratoconus is a progressive condition where the cornea thins and bulges into a cone-like shape, leading to distorted vision. For many patients, traditional contact lenses don’t fit well on the irregular corneal surface, causing discomfort and suboptimal vision correction.

How Scleral Lenses Help

Scleral lenses vault over the cornea and rest on the sclera, bypassing the uneven corneal surface entirely. The tear-filled reservoir provides a smooth optical surface, correcting visual distortions while protecting the sensitive cornea from further damage.

A Real-Life Example
One of our patients, a young professional diagnosed with keratoconus, came to us frustrated by constant discomfort and blurry vision. After being fitted with custom scleral lenses, they reported seeing clearly for the first time in years. Their confidence and quality of life improved almost immediately.

2. Dry Eye Syndrome: A Long-Awaited Relief

Dry eye syndrome can make everyday tasks like reading, working, or driving nearly impossible. Many patients find that traditional lenses exacerbate their symptoms, leaving them searching for alternatives.

The Scleral Lens Advantage

Scleral lenses act as a protective barrier, shielding the cornea while keeping it hydrated throughout the day. The saline solution in the lens reservoir soothes dryness and irritation, offering lasting relief.

For Meibomian Gland Dysfunction (MGD)
Patients with meibomian gland dysfunction often experience disruptions in tear production. Scleral lenses provide the continuous moisture their eyes need, alleviating the discomfort caused by MGD.

One of our dry eye patients described the experience of wearing scleral lenses as “life-changing,” allowing them to work longer hours without the constant burning and redness they previously endured.


3. Post-Surgical Vision Loss: Restoring Clarity

Procedures like LASIK, corneal transplants, or radial keratotomy can sometimes result in complications, such as irregular corneas or residual vision issues. For patients experiencing these challenges, scleral lenses offer a non-surgical solution that restores both comfort and clarity.

Why They Work Post-Surgery

Scleral lenses create a smooth optical surface, compensating for irregularities caused by surgery. They also protect the healing cornea, reducing the risk of irritation and further complications.

A Case Study
One of our patients, who underwent a corneal transplant, struggled with blurred vision and discomfort for years. After being fitted with scleral lenses, they were finally able to enjoy clear, stable vision and a more active lifestyle.

4. Corneal Dystrophy and Degeneration

Conditions like corneal dystrophy and degeneration can lead to vision loss and discomfort over time. These conditions often affect the cornea’s transparency and structure, making traditional lenses ineffective or uncomfortable.

Scleral Lenses as a Protective Barrier

Scleral lenses provide a cushion of fluid that protects the cornea, reduces irritation, and improves vision quality. For many patients, they are the only viable option for managing these progressive conditions.


5. Corneal Ectasia: Managing Irregularities

Corneal ectasia is a condition where the cornea becomes weak and deformed, often as a result of refractive surgeries. This can lead to blurry vision and light sensitivity, making everyday activities difficult.

How Scleral Lenses Help

By compensating for the irregular corneal surface, scleral lenses restore clarity and reduce visual distortions. They also provide a stable, comfortable fit, allowing patients to wear them throughout the day without discomfort.
