Understanding Keratoconus

Keratoconus, derived from the Greek words “kerato” meaning cornea, and “konos” meaning cone, is a degenerative eye disorder that causes the cornea to thin and gradually bulge outward into a cone-like shape. This deformation disrupts the light’s path into the eye and the retina, leading to distorted and blurry vision, nearsightedness, irregular astigmatism, and light sensitivity.

This progressive eye disease generally manifests in the early teens to the late twenties, subtly deteriorating vision. The exact cause of Keratoconus remains uncertain, although it’s believed that a combination of genetic, environmental, and hormonal factors plays a significant role. The onset can be associated with incessant eye rubbing, allergies, or it may be passed down genetically.

For an individual suffering from Keratoconus, daily tasks like reading, driving, or even recognizing faces can be daunting. It’s not just a matter of clarity; it’s about a gradual loss of life’s details, colors, and vibrancy.

While Keratoconus affects everyone differently, common symptoms include progressively worsening vision that cannot be corrected with glasses, frequent changes in eyeglass prescription, and double vision. If you experience any of these symptoms, a thorough examination by an experienced optometrist is recommended. You can learn more about the condition on our dedicated Keratoconus page.

Now that we’ve delved into the essence of Keratoconus, let’s illuminate the beacon of hope that comes in the form of Scleral Lenses. How do they work, and why are they the perfect match for this complex corneal condition? Read on to discover the fascinating details.

Introduction to Scleral Lenses

Scleral lenses, named for the sclera, or white part of the eye, are a specialized contact lens designed to vault over the entire corneal surface and rest on the white part of the eye (sclera). Due to their size and shape, they function differently from regular contact lenses. Rather than interacting with the cornea, scleral lenses create a tear-filled vault over it. This unique design allows scleral lenses to correct vision irregularities caused by conditions like Keratoconus by providing a smooth refractive surface, which corrects the distorted vision caused by an irregular cornea.

These innovative lenses are made of highly oxygen-permeable materials and have a diameter larger than typical contact lenses. They provide superior comfort as they do not touch the cornea, reducing the risk of corneal abrasions and discomfort. Additionally, the tear reservoir trapped beneath the lens can help soothe and hydrate a dry eye, offering relief to individuals experiencing dry eye syndrome.

Scleral lenses are custom-fit for each individual’s unique eye shape and vision needs. The fitting process involves detailed measurements of the eye surface and careful lens selection to ensure optimal fit, comfort, and visual acuity. For a closer look at this process, you can refer to our Scleral Lenses page.

Beyond doubt, Scleral lenses serve as an exceptional vision correction tool, yet their efficacy is exceptionally apparent in cases of corneal irregularities, like Keratoconus. Let’s examine this intriguing correlation further in the following section.

Keratoconus creates a unique set of challenges when it comes to vision correction. Traditional methods like eyeglasses and regular contact lenses often fall short because they cannot adapt to the irregular corneal surface that typifies this condition. Enter scleral lenses – a ground-breaking solution that’s changing the game for individuals grappling with Keratoconus.

Unlike standard contact lenses, scleral lenses vault over the cornea, avoiding direct contact. This design ensures that the lens’s back surface mirrors the irregularities of the cornea, while the front surface remains perfectly smooth. The result is dramatically improved vision since light can now enter the eye without being distorted by a misshapen cornea. As the lens is filled with a saline solution before insertion, it also provides a continuous bath of fluid to the eye, increasing comfort, particularly for those who experience dry eyes – a common symptom associated with Keratoconus.

What makes this pairing even more powerful is the custom-fit design of scleral lenses. Advanced technology, such as the Visante Optical Coherence Tomographer, allows eye care professionals to capture precise measurements of the eye’s surface. This data is then used to design a lens that provides an ideal fit, optimizing vision correction and comfort. To understand this technology better, visit our Visante Optical Coherence Tomography page.

Real-world experiences and research underscore the effectiveness of scleral lenses for Keratoconus. Patients report significant improvements in visual acuity, quality of life, and lens comfort. Scleral lenses have shown to be a stable, safe, and reliable form of vision correction for individuals with Keratoconus, marking a significant advancement in the field of optometry. In fact, in many cases, scleral lenses have helped patients avoid invasive procedures, such as corneal transplants, representing not only a non-surgical alternative but one that offers exceptional visual results.

Frequently Asked Questions (FAQS)

To further bolster your understanding of Keratoconus and scleral lenses, let’s dive into some frequently asked questions that many people have about these topics.

  1. What are the early signs of Keratoconus? Early signs of Keratoconus can include blurring and distortion of vision, increased sensitivity to light, and difficulty driving at night. It may often be mistaken for any other refractive error. For more information, visit our Keratoconus page.

  2. Can Keratoconus lead to blindness? While Keratoconus can significantly impair vision, it rarely leads to total blindness. However, it can make it impossible to achieve clear vision with glasses or standard soft contact lenses.

  3. What makes scleral lenses suitable for Keratoconus? Scleral lenses vault over the irregular cornea, landing on the white part of the eye (the sclera), providing a smooth refractive surface that improves vision. Additionally, they are more stable on the eye and more comfortable than traditional contact lenses.

  4. How are scleral lenses fitted? Scleral lenses are custom-fitted to your eyes using high-tech devices like the EyePrintPRO and Visante Optical Coherence Tomography.

  5. Are scleral lenses comfortable to wear? Yes. Since scleral lenses don’t touch the cornea and are instead supported by the sclera, they’re often more comfortable than standard rigid lenses, especially for sensitive or irregularly shaped corneas.

  6. Can I sleep with my scleral lenses in? No, you should always remove scleral lenses before sleeping. Sleeping in your lenses can lead to serious complications, including microbial keratitis.

  7. Who is a good candidate for scleral lenses? Scleral lenses can benefit people with a variety of eye conditions, not just Keratoconus. They’re especially useful for those with severe dry eye, graft-versus-host disease (GVHD), Sjogren’s syndrome, or those who’ve had a corneal transplant.

  8. How long do scleral lenses last? Scleral lenses typically last one to three years, depending on care and handling. Regular check-ups are important to ensure the lenses are still fitting well and providing the best possible vision.
