Living with keratoconus can make clear, comfortable vision challenging, especially in Nevada's dry, dusty climate. For patients in Henderson, wind, airborne debris, dry air, and intense sunlight can add to visual discomfort. Scleral lenses offer a specialized option designed to improve vision over an irregular cornea while providing a fluid-filled layer over the eye's surface. At Eyes on Eastern in Henderson, we evaluate patients with keratoconus and determine whether specialty contact lenses may provide clearer, more stable vision.

Why Keratoconus Can Make Glare More Noticeable

Keratoconus causes the cornea to become thinner and develop an irregular, cone-like shape. This irregularity can prevent light from focusing evenly inside the eye, which may lead to blurry or distorted vision, glare, halos, and difficulty seeing at night.

Nevada's bright sunlight can make these symptoms even more noticeable. Standard glasses or traditional soft contact lenses may not fully correct the irregular astigmatism caused by keratoconus. Scleral lenses are different because their rigid optical surface can help compensate for corneal irregularities and create clearer, more consistent vision.

How Scleral Lenses Work

Scleral lenses are larger than standard contact lenses. Instead of resting directly on the cornea, they vault over it and rest on the white portion of the eye. A preservative-free saline solution fills the space between the lens and the cornea, creating a fluid reservoir during wear.

For someone with keratoconus, this design can provide several benefits:

Creates a smooth optical surface to improve vision affected by irregular astigmatism
Maintains a fluid reservoir over the cornea throughout wear
Reduces direct contact between the lens and the sensitive corneal surface
May improve visual quality when glare, halos, or distortion are present
Offers a stable fit that can be customized for an individual's eye shape

Managing Nevada's Dry, Dusty Conditions

Henderson's desert environment can be difficult for people who already experience sensitive or uncomfortable eyes. Because scleral lenses cover the cornea and maintain fluid beneath the lens, they can help keep the ocular surface hydrated while worn.

The lens also creates a physical barrier over the cornea, which can reduce direct exposure of the corneal surface to environmental irritants. However, scleral lenses are not protective goggles, and windblown dust can still collect on or around a contact lens. Wearing sunglasses or appropriate protective eyewear during especially dusty or windy conditions can provide additional protection.

Proper lens cleaning is also especially important in Nevada's dusty environment. Scleral lenses should be cleaned and disinfected as directed and filled with the appropriate preservative-free sterile solution before insertion.

Customized Scleral Lens Fittings in Henderson

Keratoconus affects every cornea differently, so scleral lenses require a personalized fitting. We evaluate the shape and health of the cornea, vision needs, lens alignment, and comfort to determine the appropriate specialty contact lens approach.
