The Benefits of Scleral Lenses for Patients With Keratoconus

A degenerative condition called keratoconus causes the cornea to thin and bulge outward into a cone shape. It impairs vision and increases sensitivity to light. Glasses and traditional contact lenses can help manage the condition, but they cannot provide adequate vision correction for more severe cases. Fortunately, there is a solution: scleral lenses. 

 

 

What Are Scleral Lenses?

 

 

Scleral lenses are large-diameter contacts that are purposely designed to sit on the sclera, the eye's white part. They create a vault over the cornea, providing a tear-filled chamber. This feature can improve vision and comfort for people with corneal irregularities like keratoconus.

 

 

Improved Visual Acuity

 

 

Scleral lenses can provide better visual acuity than traditional glasses or contacts. They are particularly beneficial to people with severe keratoconus. The larger lens size allows for complete coverage of the cornea. This reduces distortions and provides a more uniform refractive surface.

 

 

Reduced Distortions

 

 

Keratoconus can cause significant distortions in vision. Scleral lenses can correct these distortions by creating a smooth refractive surface over the cornea, resulting in a more precise and stable vision.

 

 

Increased Comfort

 

 

The unique scleral lens design can improve comfort for people with keratoconus. Since the lens rests on the sclera rather than the cornea, friction and irritation are reduced. Also, the tear-filled chamber can provide constant lubrication, reducing dryness and irritation.

 

 

Reduced Light Sensitivity

 

 

The uneven shape of the cornea in keratoconus patients can make them more sensitive to light. Scleral lenses can help reduce sensitivity by creating a shield over the cornea. This blocks out excess light and provides a more comfortable visual experience.

 

 

Improved Depth Perception

 

 

Keratoconus can affect depth perception, making it difficult to judge distances and navigate in 3D environments. The lenses can improve depth perception by providing more consistent visual information. This allows for more accurate depth perception and spatial awareness.

 

 

Improved Quality of Life

 

 

Scleral lenses can improve the quality of life for keratoconus patients. Enhanced visual acuity and comfort can make daily driving and reading easier. Moreover, reduced light sensitivity can allow for more comfortable outdoor activities.

 

 

Longevity

 

 

Scleral lenses are durable and can last for several years with proper care. For those with keratoconus, these lenses may be beneficial. Changes in the shape of the cornea may cause more frequent replacement of traditional glasses and contacts.

 

 

Customizable

 

 

Scleral lenses are highly customizable. This feature allows for a precise fit that can provide optimal visual correction and comfort. Your eye doctor can fit your lenses to your eye's specific shape and size. This offers a unique solution for each individual with keratoconus.

 

 

Alternative to Surgery

 

 

Scleral lenses can provide a noninvasive alternative that can achieve results similar to surgery in visual acuity and comfort.

 

 

Conclusion 

 

 

Scleral lenses can be a beneficial treatment option for patients with keratoconus. Do you suffer from keratoconus or another eye condition? Discuss the advantages with an eye care professional to discover if scleral lenses suit you.
