The Role of Specialty Contact Lenses in Keratoconus Management

Keratoconus is a progressive eye condition that causes the cornea to thin and bulge into a cone-like shape, leading to distorted vision. For many patients, traditional glasses and soft contact lenses are not enough to provide clear, comfortable vision. At Eyecare Associates Optometric Group, we understand how important it is to provide personalized, effective solutions for patients with keratoconus, and specialty lenses are a key part of that care.

Why Specialty Lenses Matter

As keratoconus progresses, the irregular shape of the cornea makes it difficult for conventional lenses to fit properly or correct vision adequately. Specialty contact lenses are designed to provide a more stable fit and improve visual clarity by creating a smooth refractive surface over the irregular cornea. Several types of specialty lenses are used to manage keratoconus, each with unique benefits.

Rigid Gas Permeable (RGP) Lenses

These small, firm lenses maintain their shape on the eye, allowing them to mask the irregular corneal surface and provide clearer vision. They are often a first-line option for mild to moderate keratoconus because of their ability to significantly improve visual acuity where glasses and soft contacts fall short.

RGP lenses work by creating a smooth refractive surface that compensates for the misshapen cornea. Although they are smaller in diameter than other specialty lenses, their durability and breathability make them a reliable option for many patients. These lenses allow high levels of oxygen to reach the eye, which helps maintain corneal health over time.

Hybrid Lenses

Combining the best of both worlds, hybrid lenses feature a rigid center surrounded by a soft skirt. This design allows for sharp vision like RGP lenses but with the added comfort of soft lenses. They are a great option for patients who struggle with RGP lenses but do not require the full vaulting effect of scleral lenses.

Scleral Lenses

Scleral lenses are larger than standard contacts and rest on the white part of the eye (the sclera) rather than the cornea. They vault over the cornea and create a fluid-filled chamber that helps smooth out the corneal irregularities while keeping the eye hydrated and comfortable. They are often the best option for advanced keratoconus.

The Importance of Custom Fitting

No two cases of keratoconus are exactly the same, which is why custom fitting is essential. Our optometrists use advanced diagnostic tools, such as corneal topography and anterior segment imaging, to map the shape of the cornea and determine the best lens option. We work closely with each patient to ensure a precise fit and optimal comfort.

With proper care and regular monitoring, specialty contact lenses can offer long-term vision improvement and eye health management for keratoconus patients. While they do not stop the progression of the condition, they greatly enhance visual function and quality of life.
