Scleral Lenses for Keratoconus
Scleral Lenses: Advanced Vision Solutions for Keratoconus
Scleral lenses, including mini-scleral and custom scleral options, represent a newer technology in the treatment of keratoconus. These lenses have quickly become the standard of care, offering both exceptional clarity and unparalleled comfort for those with keratoconus.
Benefits of Scleral Lenses
Scleral lenses cover a larger portion of the sclera, or white part of the eye, unlike traditional contact lenses. They maintain a fluid reservoir that soothes the cornea, providing continuous hydration, which is beneficial for keratoconus patients. This design ensures that the lenses are stable and centrally aligned, minimizing the risks of dislocation and offering sharp, stable vision while correcting distortions such as glare, ghosting, halos, and starbursts.
How Scleral Lenses Work
The design of scleral lenses allows them to vault over the cornea without touching it, creating a smooth optical surface that corrects vision issues caused by the irregular cornea typical of keratoconus. The larger diameter and unique fitting of these lenses ensure that they encapsulate the irregularities of the cornea, leading to improved comfort and reduced sensation of foreign bodies in the eye.
Customization and Fitting
Customizing scleral lenses requires precise and detailed corneal mapping to ensure that each lens fits perfectly according to the individual’s unique ocular surface topography. This process typically involves advanced imaging techniques to capture the exact shape and contours of the cornea, allowing for a tailored fit that addresses specific needs and conditions of keratoconus.
Long-term Use and Care
Scleral lenses are designed for long-term use, with proper maintenance and regular cleaning to ensure optimal performance and eye health. These lenses are generally replaced annually, and patients are advised to adhere to a meticulous care routine. Regular follow-up appointments are crucial to monitor the condition of both the lenses and the health of the eyes.
The Superiority of Scleral Lenses
For patients with keratoconus, scleral lenses provide a superior alternative to traditional methods, combining the visual benefits of RGP lenses with the comfort of soft lenses. By addressing both the quantitative and qualitative visual symptoms of keratoconus, scleral lenses allow patients to enjoy a higher quality of life without the need for surgical intervention.
The Evolution of Contact Lens Technology
While Hybrid lenses are still a viable option for many, advancements in contact lens technology have introduced a variety of alternatives that cater to different needs and preferences. Today, keratoconus patients can choose from several innovative types of lenses, including:
- RGP Lenses: Rigid Gas Permeable lenses provide a durable, stable fit, maintaining shape on the eye to correct the irregular corneal surface of keratoconus, offering sharp, clear vision.
- SynergEyes Hybrid Lenses: These combine a rigid center with a soft lens perimeter, offering the clarity of RGPs with the comfort of soft lenses.
- Scleral Lenses: Larger in diameter than traditional contact lenses, scleral lenses vault over the cornea and rest on the sclera, providing excellent comfort and stable vision.
- PROSE Lenses: Customized prosthetic devices that help maintain a healthy ocular surface and improve vision.
- EyePrint PRO Lenses: Tailored specifically to the unique contours of the patient’s eye, offering a precise fit for those with highly irregular corneas.
Our Approach to Keratoconus Contact Lenses
At our practice, we focus on designing and prescribing highly customized contact lenses made specifically for keratoconus. Using these advanced lens options, the majority of our patients achieve corrected vision without the need for surgical procedures, such as corneal transplants or corneal implants (Intacs). We are also skilled in managing post-surgical vision challenges, helping those who have undergone such procedures but still face vision issues.
Keratoconus contact lenses aim to improve visual acuity (e.g., achieving 20/20 vision) and correct Higher Order Aberrations (HOAs). By addressing these complex visual defects, the lenses effectively reduce symptoms like glare, halos, ghosting, starbursts, and double vision, enhancing overall visual quality and precision
Choosing the Right Lens for You
Each type of lens offers unique benefits, and the best choice depends on individual factors like the severity of keratoconus, the shape of the cornea, and personal comfort preferences. During your consultation, we will conduct a comprehensive evaluation to determine the most effective lens type for your specific condition.
Our commitment is to empower you with clear, consistent vision and long-term eye health, enabling you to lead a normal, productive life. Schedule your appointment today to explore the best lens options for your keratoconus treatment.
Dr. Irwin Azman, and Dr. Benjamin Azman, Keratoconus Specialists, prescribe scleral lenses for a variety of hard-to-fit eyes, including patients with Stevens-Johnson Syndrome, Radial Keratotomy / Lasik Complications and Lasik failures, Keratoconus, Corneal Ectasia, Post-Surgical Vision Loss, Pellucid Marginal Degeneration, and other irregular corneas.
Dr. Azman, one of the country’s top Keratoconus Specialists neither avoids nor declines the challenge of prescribing the most difficult cases.
