In its simplest definition; Keratoconus is a thinning of the cornea, causing cone like protrusion.
Keratoconus leaves the surface of the cornea non-symmetrical, and in turn all light that passes through a keratoconic cornea will be irregularly dispersed. This is why, in most cases, eye glasses alone will not work to correct vision on an irregularly shaped cornea.

The best options for improving vision immediately when Keratoconus is present are contact lenses. The specialists at Obrig take all factors into account to find the best lens system for all patients, including those affected by Keratoconus.
In most cases, soft lenses alone will not work. Simply stated putting a soft lens on top of an irregular surface will cause the soft lens to rest asymmetrical, resulting in no meaningful vision correction.
Specially designed gas permeable contact lenses are usually used and can provide superb vision for many people dealing with Keratoconus. As you can see from the images, each eye is incredibly different, especially those that have Keratoconus. There is not one lens style that will work for every eye, and in these situations, there are no hard set fitting rules. A well fit lens is fit by an experienced contact lens specialist, such as those at Obrig.
These are just a few of the styles of contact lenses that can be used to improve the vision of those with Keratoconus and other irregular corneas; such as post-transplant and pellucid marginal degeneration.
It is extremely important to let the specialists at Obrig decide which form of lens would be best suited for your eyes.
We look forward to seeing you soon.
