The Lens Revelation: Unlocking the Benefits of Scleral Lenses

Understanding Keratoconus and Hard Contact Lenses

For individuals with keratoconus, a progressive eye condition that causes thinning and bulging of the cornea, finding the right vision correction method can be challenging. Traditional contact lenses may not provide the necessary comfort and visual clarity. However, hard contact lenses, including scleral lenses, have emerged as an effective solution. Let’s delve into the details of keratoconus, the challenges of traditional contact lenses, and the introduction of scleral lenses.

What is Keratoconus?

Keratoconus is a corneal disorder characterized by the thinning and cone-shaped bulging of the cornea. This abnormal corneal shape results in distorted vision, sensitivity to light, and difficulty in wearing regular contact lenses or glasses. Keratoconus typically affects both eyes and often begins during the teenage years or early adulthood.

Challenges of Traditional Contact Lenses

Traditional contact lenses, such as soft or rigid gas-permeable lenses, may not adequately address the visual needs of individuals with keratoconus. The irregular shape of the cornea in keratoconus makes it difficult for these lenses to achieve a proper fit, resulting in discomfort, poor visual clarity, and lens movement on the eye. This can significantly impact the quality of life and day-to-day activities of those with keratoconus.

Introduction to Scleral Lenses

Scleral lenses have revolutionized the field of vision correction for individuals with keratoconus. These specialized contact lenses are larger in diameter and vault over the entire cornea, resting on the sclera (white part of the eye). By creating a liquid-filled chamber between the lens and the cornea, scleral lenses provide numerous benefits for keratoconus patients.

Scleral lenses offer a more secure and stable fit compared to traditional contact lenses, as they do not rely solely on the shape of the cornea for positioning. The liquid reservoir between the lens and the cornea helps to maintain a smooth optical surface, resulting in improved visual clarity. Additionally, the presence of the liquid layer can provide relief for individuals with dry eyes, a common symptom associated with keratoconus.

Customization and Individualized Care

When it comes to scleral lenses, one of their greatest advantages is the level of customization and individualized care they offer. This section will explore the fitting process for scleral lenses and the importance of ongoing monitoring and adjustments.

Fitting Process for Scleral Lenses

The fitting process for scleral lenses is a comprehensive and personalized procedure. It begins with a thorough evaluation of your eyes by an optometrist or an ophthalmologist specializing in contact lenses. During this evaluation, measurements of your cornea and eye shape are taken to ensure the proper fit of the lenses.

One of the key steps in the fitting process is the creation of an impression or mold of your eye’s surface. This mold helps in the custom design and fabrication of the scleral lenses. The mold is used to create lenses that precisely match the unique contours of your eyes, providing optimal comfort and visual acuity.

The fitting process also involves trial lenses to determine the ideal lens size, shape, and parameters for your specific needs. These trial lenses are typically worn for a period of time to assess their fit, comfort, and overall performance. Your eye care professional will closely monitor your experience with the trial lenses and make any necessary adjustments to ensure a perfect fit.
