Keratoconus is a progressive eye condition that affects the shape of the cornea, leading to distorted vision. This condition can make everyday tasks, such as reading or driving, more challenging. While traditional glasses and soft contact lenses may not always provide relief, specialty contacts present an alternative that caters to the unique needs of individuals with keratoconus.
What Are Specialty Contact Lenses?
Specialty contact lenses refer to custom-designed lenses created to cater to irregularly shaped corneas. Unlike standard lenses, specialty lenses are tailored to fit the specific shape and curvature of the keratoconic cornea. Several types of specialty lenses may be used, including rigid gas permeable (RGP) lenses, scleral lenses, and hybrid lenses.
RGP lenses are smaller and rest directly on the cornea, providing a smooth refractive surface. Scleral lenses extend beyond the cornea and rest on the sclera, or the white part of the eye, creating a tear-filled reservoir that enhances comfort. Hybrid lenses combine the features of both RGP and soft contact lenses by integrating a rigid center with a softer edge. Each type of lens offers unique features that make it adaptable for individuals with different stages of keratoconus.
Benefits of Specialty Contact Lenses for Keratoconus
Specialty contact lenses are designed to improve vision for individuals whose eyes have irregular corneal shapes. These lenses provide a smooth surface that allows light to enter the eye more effectively, helping reduce visual distortion. The customization of these lenses may enhance their ability to accommodate the varying degrees of corneal irregularity.
Another benefit of specialty lenses is their potential to improve comfort. The designs of scleral lenses shield the sensitive corneal surface, which can reduce irritation during wear. Hybrid lenses, with their soft edges, may also provide a comfortable option for individuals who have difficulty adapting to rigid designs.
How Specialty Lenses Enhance Daily Life
Individuals with keratoconus may face challenges in performing everyday tasks due to blurred or distorted vision. Tasks that require precise visual focus, such as reading a computer screen or recognizing faces, can become difficult. Specialty contact lenses aim to improve clarity, which can help address these challenges. Clearer vision can make activities such as working, driving, or participating in social interactions less stressful. The increased comfort of specialty lenses may also promote longer wear times. This can enable users to maintain a consistent routine throughout the day.
Fitting Process for Specialty Contact Lenses
Fitting specialty lenses for individuals with keratoconus may involve a detailed process to achieve the right balance between comfort and function. An optometrist or ophthalmologist performs a thorough eye examination, which includes mapping the cornea’s shape and measuring its irregularities. These measurements guide the customization of the lens to fit the unique contours of the cornea.
Once the lenses are created, they are tested to assess their fit and function. The specialist may use a dye test to evaluate lens positioning, making sure no unnecessary pressure is applied to sensitive areas of the cornea. Adjustments may also be made to address specific concerns such as discomfort or imperfect visual alignment.
