What is Radial Keratotomy (RK)?
Radial Keratotomy (RK) was a popular surgical procedure aimed at enhancing vision for individuals struggling with nearsightedness. However, despite its initial success, many patients have experienced complications such as high astigmatism, leading to a decline in their visual acuity. Fortunately, advancements in technology have introduced scleral lenses as a remarkable solution for improving vision in individuals with RK-related astigmatism.
Understanding Radial Keratotomy Complications
Although RK was once considered an effective method for correcting nearsightedness, it can result in complications that impair vision. One such complication is high astigmatism, where patients experience distorted and blurry vision due to an irregular corneal shape. This can be particularly frustrating for individuals whose initial goal was to improve their vision through RK.
The Role of Scleral Lenses in RK-Related Astigmatism
Scleral lenses have emerged as a game-changer for individuals experiencing astigmatism following RK surgery. These specialized lenses cover a larger portion of the eye compared to traditional contact lenses. Their unique design creates a reservoir of fluid between the lens and the cornea, allowing for a more consistent and stable vision correction.
The benefits of scleral lenses for individuals with RK-related astigmatism:
- Improved Visual Acuity: Due to their ability to bridge the gap created by an irregular cornea, scleral lenses provide enhanced visual acuity. This is especially advantageous for those struggling with astigmatism following RK surgery.
- Enhanced Comfort: Unlike traditional contact lenses, which sit on the cornea, scleral lenses vault over the cornea, making them more comfortable for individuals with compromised corneal surfaces.
- Long-Lasting Solution: Scleral lenses not only provide relief from astigmatism but also offer long-term stability. They can be custom-made to fit the unique shape and size of an individual’s eye, ensuring optimal visual correction.
- Protection and Moisture Retention: The fluid-filled reservoir between the lens and the cornea acts as a cushion, protecting the cornea from external irritants and ensuring constant hydration. This is particularly beneficial for individuals with dry eyes, a common issue among post-RK patients.
Consultation and Fitting for Scleral Lenses
To obtain the maximum benefit from scleral lenses, it is vital to consult an experienced optometrist or ophthalmologist who specializes in fitting them correctly. Since scleral lenses are custom-made to fit an individual’s eye, accurate measurements and fittings are crucial to ensure optimal vision correction.
During the fitting process, the eye care professional will evaluate the size and shape of the individual’s eye, allowing for the creation of a tailored scleral lens. Moreover, the eye care professional will provide guidance on proper usage, care, and maintenance to keep the lenses clean and comfortable.
