Living with Keratoconus: How Scleral Lenses Can Improve Your Quality of Life

Keratoconus is a progressive eye condition that causes the cornea, the clear front part of the eye, to thin and bulge into a cone-like shape. This irregular shape distorts light as it enters the eye, leading to blurred and distorted vision. Keratoconus typically begins in the teenage years and can continue to worsen over time, affecting both eyes. Factors like excessive eye rubbing, certain medical conditions, and exposure to ultraviolet (UV) light may contribute to the development and progression of keratoconus.

The Impact of Keratoconus on Vision and Eye Health

Keratoconus can have a profound impact on both vision and overall eye health. As the condition progresses, the cornea thins and changes shape, leading to various vision problems. Common symptoms include blurred or distorted vision, increased sensitivity to glare and light, and difficulty driving, especially at night. Individuals with keratoconus may also experience frequent changes in their prescription for corrective lenses. In severe cases, even glasses or contact lenses may not fully correct visual acuity.

Beyond these vision problems, keratoconus can contribute to other eye health issues. One such complication is corneal scarring, which results from the cornea's irregular shape and can further impair vision. In some cases, the thinning of the cornea can lead to a condition called corneal hydrops, where a sudden break in the corneal lining causes swelling and a temporary worsening of vision. Additionally, the altered shape of the cornea can increase the risk of eye infections, such as bacterial keratitis, making proper eye care and management essential for those affected by keratoconus.

Exploring Specialty Contact Lenses for Keratoconus

There are several treatment options available for managing keratoconus, including specialty contact lenses. These custom-made lenses are designed to address the unique shape and needs of the keratoconic cornea, providing improved vision and comfort.

One of the most effective types of specialty contact lenses for keratoconus is scleral lenses. Scleral lenses are larger than traditional contact lenses and rest on the white part of the eye (the sclera) rather than directly on the cornea. This design helps to create a smooth, regular surface over the irregularly shaped cornea, improving visual acuity and reducing distortion.

How Do Scleral Lenses Work to Treat Keratoconus?

Scleral lenses work to treat keratoconus in several ways. The large diameter of scleral lenses allows them to vault over the cornea, creating a space between the lens and the corneal surface. This space is filled with a saline solution, which helps to smooth out the irregular corneal shape.

By creating a smooth, regular surface over the cornea, scleral lenses can significantly improve your visual acuity, reducing the distortion and blurriness associated with keratoconus. The scleral lens rests on the white part of the eye, rather than directly on the cornea, which can be more comfortable for those with keratoconus. This design helps to minimize any discomfort or irritation caused by the irregular corneal shape. Scleral lenses can also help to protect the cornea from further damage or distortion, slowing the progression of keratoconus.

The Benefits of Scleral Lenses for Keratoconus Patients

Wearing scleral lenses can provide a range of benefits for individuals living with keratoconus, including:

·       Improved visual acuity: Scleral lenses can significantly improve your visual clarity and reduce distortion, allowing you to see more clearly and comfortably.

·       Enhanced comfort: The scleral lens design helps to minimize any discomfort or irritation caused by the irregular corneal shape, making them a more comfortable option compared to traditional contact lenses.

·       Slowed progression of keratoconus: By protecting the cornea and providing a stable, regular surface, scleral lenses can help to slow the progression of keratoconus, potentially delaying the need for more invasive treatments, such as corneal transplants.

·       Versatility: Scleral lenses can be customized to address a wide range of vision needs, making them a suitable option for individuals with varying degrees of keratoconus severity.
