2019年3月3日 · Scleral contacts are large-diameter gas permeable contact lenses specially designed to vault over the entire corneal surface and rest on the "white" of the eye (sclera).

Scleral lenses represent a major advance in keratoconus management, offering enhanced visual acuity, comfort, and corneal protection. Their evolving technology and customization make them a preferred option for many.

Scleral lenses are larger than all other types of contact lenses. Their larger size allows them to vault over the cornea and rest on the sclera, the white part of the eye, avoiding contact with the sensitive, bulging cornea and reducing the risk of corneal injury.

2024年6月18日 · For most people with keratoconus, keratoconus contact lenses are an excellent non-surgical option and provide the best quality of vision possible for the individual. Let’s delve into the prescribing process and the different kinds of contact lenses which are available to keratoconus patients.

Keratoconus lenses are specialized contact lenses that can accommodate the sharp, steep curves found in keratoconus. The most common keratoconus lenses are usually rigid gas permeable, hybrid or scleral lenses with the latter having the highest success rate.

Scleral lenses are a type of contact lens large enough to cover the entire cornea and sit on the sclera (the white of the eye). They’re a type of rigid gas-permeable contact lens —meaning they hold their shape and allow an adequate supply of oxygen to reach the eye’s surface.

Custom-designed scleral lenses help patients with corneal irregularities achieve dramatic improvements in visual acuity and comfort. Scleral lenses vault over the cornea and rest on the sclera while avoiding the diseased cornea.

2022年7月23日 · To put it simply, the scleral lens works by masking our misshapen cornea, thus tricking our brain into believing we have a healthy cornea. In this article we will discuss how the scleral lens works for those of us with keratoconus. As mentioned above, the lens masks our damaged cornea. The result is a temporary correction of our refraction error.

2019年1月9日 · Scleral contacts are larger in diameter than conventional gas permeable (GP) contact lenses, which allows them to vault over even relatively large areas of distorted cornea, eliminating much of the irregular astigmatism and other refractive errors caused by keratoconus.

2024年10月9日 · Scleral Lenses. Scleral lenses are larger than your cornea, so they completely vault over the "cone," making a new, smooth surface for light to focus on. They offer good comfort, especially if your eyes are very sensitive. Soft Lenses. Soft lenses are still an option early on in keratoconus but may not give you perfectly crisp vision.
