There are various ways to treat dry eye syndrome, eyedrops being the most common option. The success of the treatment will depend on factors such as the severity of the condition and the underlying cause. Unfortunately, most traditional treatments only provide temporary relief. Doctors looking at alternative options are increasingly recommending specialty contact lenses to treat dry eye. 

Scleral Lenses for Dry Eye 

Scleral lenses are usually prescribed to treat refractive errors and corneal irregularities. Studies confirm their efficacy as a dry eye treatment. Patients with severe dry eye can benefit from specialized contact lenses. 

Reports show that most patients tolerate them well, with many citing relief of symptoms and improved visual acuity. Additional research is necessary to compare different types and sizes of lenses. 

The Lenses Vault Over the Cornea

Most people with dry eyes find it almost impossible to wear contact lenses for vision correction. Regular lenses sit directly on the cornea, which can cause extreme irritation and exacerbate dry eye symptoms. 

The soft lenses also soak up moisture, leaving the eye dry. Scleral lenses go over the cornea surface, lying on the white of the eye (sclera). The lenses do not touch the sensitive cornea surface, reducing irritation. 

Ensuring Constant Hydration

Scleral lenses are designed to provide constant hydration to the eye. The space between the lens and the cornea is filled with a special saline solution. The solution provides constant hydration, keeping the eye moist and healthy and relieving dry eye. Adding artificial tears and an antibiotic into the lens bowl before insertion can help maintain lubrication. It also helps boost the healing of the ocular surface. 

Protecting the Cornea Surface

Dry eye syndrome leaves the eyes sensitive and more vulnerable to further injury or scarring. Sometimes, the simple act of blinking can cause severe cornea irritation from eyelid friction. Scleral contact lenses can protect the cornea surface by acting as a shield between the eye and the inner eyelids. They also protect the cornea from environmental elements such as dust and wind, preventing further damage. 

Healthy Eye Appearance 

Dry eyes usually look red and unhealthy, partly due to the condition but also due to frequent eye rubbing. Common symptoms of dry eye include irritation and the sensation of something in the eye. Insufficient hydration and injury from blinking can leave the eyes looking bloodshot. Scleral lenses can help protect the cornea while providing constant hydration, leaving the eyes looking clear and healthy. 

Improved Quality of Life 

Patients can continue using artificial tears or eyedrops while wearing contact lenses. However, those who wear scleral lenses find they do not need artificial tears as frequently. Most only use eye drops at night after removing the lenses. 

Scleral lenses can help improve an individual’s quality of life in three ways. They help protect the eyes, provide visual correction, and keep the eyes lubricated. The lenses reduce eye irritation and relieve the symptoms of dry eye. An eye exam will help determine if you are a good candidate for scleral lenses.
