Eyes Wide Open: Exploring the World of Scleral Lens Technology

Welcome to the world of scleral lenses. A world where technological advancements have made it possible to manage numerous eye conditions using a simple, yet highly effective tool. The scleral lens has revolutionized the way we approach ocular health issues.

 

How Scleral Lens Technology Works

The working principle of scleral lenses revolves around their design and fitting. The lens, larger in diameter than standard contacts, is designed to vault over the entire corneal surface and rest on the sclera. This vaulting creates a fluid-filled space over the cornea, which aids in healing and comfort. The fitting process, though more complex than traditional lenses, ensures a comfortable and stable fit.

The material used in scleral lenses is another crucial aspect of how they work. These lenses are made from highly breathable rigid gas permeable (RGP) materials. This type of material allows for excellent oxygen transmission, ensuring the cornea stays healthy while wearing the lenses.

Applications of Scleral Lenses

The applications of scleral lenses are wide and varied. They are primarily used to manage corneal irregularities such as keratoconus, pellucid marginal degeneration, and post-surgical corneal ectasia. They are also used for people who have undergone corneal grafts and those with severe dry eyes.

Scleral lenses are also beneficial in managing ocular surface diseases like Sjogren's syndrome, graft versus host disease, and Stevens-Johnson syndrome. They provide a stable tear film and protect the corneal surface from the mechanical effects of blinking, thus providing symptomatic relief.

In addition, scleral lenses are also used in correcting refractive errors like myopia, hyperopia, astigmatism, and presbyopia. They can be a great alternative to glasses or regular contact lenses for those seeking a high level of visual acuity.

The Benefits of Using Scleral Lenses

The benefits of using scleral lenses are numerous. They offer superior comfort and stability, especially for those with sensitive or irregular corneas. The large diameter and unique fitting technique ensure the lenses remain stable on the eye, reducing the risk of displacement.

Scleral lenses also provide excellent visual acuity. Because they vault over the cornea, they can create a smooth optical surface, which can dramatically improve vision in individuals with corneal irregularities.

Another significant benefit is their ability to retain moisture. The fluid reservoir between the lens and cornea helps to keep the eye lubricated, providing relief for those with severe dry eye conditions.

How to Care for Scleral Lenses

Like all contact lenses, scleral lenses require proper care and maintenance to ensure they remain effective and safe. This involves cleaning, disinfecting, and storing the lenses correctly.

Cleaning is best done using a recommended lens cleaner, rubbing the lens gently to remove any deposits. After cleaning, the lenses should be rinsed thoroughly and disinfected overnight using a multipurpose solution. It's also important to regularly inspect the lenses for any damage or deposits and to replace them as recommended by your eye care professional.

Storage of scleral lenses should be in a clean lens case, filled with fresh disinfecting solution. The case should also be cleaned regularly, to prevent the growth of bacteria or fungi.

Are Scleral Lenses Right for You?
