Understanding Keratoconus and Contact Lens Options

Contact Lens for Keratoconus

Keratoconus is a progressive eye disease characterized by the thinning and bulging of the cornea into a cone-like shape, resulting in distorted and blurry vision. For individuals diagnosed with this condition, vision correction options are vital for maintaining quality of life. While eyeglasses can correct vision in the early stages, specialty contact lenses are often a superior option for managing keratoconus as the condition progresses. Modern advancements in lens technology provide a range of specialized options designed to meet the unique challenges posed by keratoconus.

At the Weston Contact Lens Institute, our eye doctors work closely with each one of our patients not only to diagnose this serious condition but provide them with clear vision going forward by putting together a treatment plan. We take great care in providing our patients with the information and direction that they need to make the best decision when it comes to the type of contact lens that would be right for them.

Soft Contact Lenses

Soft contact lenses are not the most common solution for keratoconus, especially in advanced cases, but they can be a good choice for patients in the early stages of the condition. These lenses are made from soft materials and can sometimes be customized to provide an improved fit for irregular corneas. While soft lenses may not offer the same level of visual clarity as rigid options, they are comfortable, which can be a deciding factor for patients who struggle to tolerate harder lenses.

For those who opt for soft lenses, recent innovations in materials and designs have improved their ability to correct vision and provide good comfort to patients. Some specialized soft lenses feature varying thicknesses or advanced materials that can better adapt to the irregular shape of the cornea.

Rigid Gas Permeable Lenses

Rigid gas permeable (RGP) lenses are a widely recommended option for individuals with keratoconus, particularly those in moderate to advanced stages of the disease. These lenses are manufactured from firm, oxygen-permeable materials that allow the cornea to “breathe”. Unlike soft lenses, RGP lenses do not conform to the irregular shape of the cornea. Instead, they create a smooth optical surface that corrects vision.

Although RGP lenses offer excellent visual clarity, they can take time to get used to, and some patients find them less comfortable for extended periods. However, their durability and effectiveness often outweigh the initial challenges. With proper care and consistent wear, RGP lenses can significantly enhance the quality of vision for keratoconus patients.

Scleral Lenses

Scleral lenses are considered the gold standard for keratoconus patients due to their ability to provide both exceptional vision correction and unparalleled comfort. These lenses are larger than traditional contact lenses and rest on the sclera, the white part of the eye, rather than the cornea. This unique design allows scleral lenses to vault over the irregular cornea, creating a smooth optical surface that improves vision.

An additional benefit of scleral lenses is their built-in reservoir, which collects tears and keeps the eye hydrated throughout the day. This feature is particularly beneficial for individuals who experience dryness or irritation. The larger size of the lens also minimizes movement, ensuring stability and comfort during wear. Scleral lenses are often the top choice for patients with advanced keratoconus who need a reliable and effective solution.

Hybrid Lenses

Hybrid contact lenses offer a blend of the features found in both soft and rigid lenses, making them an excellent choice for many keratoconus patients. These lenses have a rigid central zone that provides sharp vision correction, surrounded by a soft outer skirt that enhances comfort. This combination allows hybrid lenses to deliver the clarity of RGP lenses while maintaining the ease of wear associated with soft lenses.

Hybrid lenses are designed to promote oxygen flow and support tear exchange, ensuring the eyes remain healthy during use. Although they may require a brief adjustment period, many patients find that hybrid lenses provide a comfortable and effective solution for managing keratoconus. Their familiar fit makes them a particularly attractive option for individuals transitioning from traditional lenses.

Finding the Best Lens for You

Choosing the right contact lens for keratoconus requires careful consideration of your specific needs, including the severity of the condition, your lifestyle, and your tolerance for different materials. Each lens type has its own advantages, and finding the perfect fit often involves a process of trial and error guided by an experienced eye care professional. Regular follow-ups and adjustments are crucial to ensure that your lenses continue to provide the best possible vision and comfort.
