A long-term study shows that about one in 2,000 individuals in the United States are diagnosed with keratoconus, an eye disorder marked by progressive thinning of the cornea. This condition causes the cornea to bulge in a cone shape and can cause problems such as blurry or distorted vision or sensitivity to light.
Contact lenses are a very popular choice for patients who need to use prescription eyewear, but who don’t want the inconvenience and hassle of wearing glasses all the time. Some people opt to only use contact lenses, while others rely on a combination of glasses and contacts, swapping between the two as and when they want or need to. However, regardless of whether you wear contact lenses full time or not, you will still need a separate contact lens exam and fitting appointment. You’ll also need to find out about the best way to take care of your contacts and your eyes themselves in order to keep them healthy.
Specialty contact lenses are used to correct irregular cornea conditions. They come in a larger design that vaults over the cornea. They cover the cornea completely with support from the sclera. This makes them comfortable because they do not disturb the sensitive cornea.
Corneal refractive therapy, or orthokeratology, is used to lessen myopia. You’ll wear rigid gas-permeable contact lenses when you sleep, and over time, the lenses will reshape your cornea. If you’re considering orthokeratology, you probably want to know the benefits. Let’s go over some of the most common benefits patients enjoy when undergoing this treatment.
