is a non-inflammatory abnormality of the cornea, which caused by changes in the structure of the cornea. It causes the cornea to thin and bulge outward in a cone shape or drooping. However, this condition can impair vision.
Keratoconus can be treated in several ways, include:
- Glasses can be worn in the early stages of the disease, when the cornea has not consequentially changed.
- Contact lenses can be used when astigmatism is too severe for glasses.
- Corneal transplant if the condition worsens.
Currently, there is a search for treatment options that stop the changing of the cornea, Thus, limiting the need for corneal transplant, including:
- Intrastromal corneal ring segment implantation (ICRS). This involves an insertion of a ring into the cornea to reduce its curvature.
- Corneal collagen cross-linking with riboflavin (CXL). This involves the use of riboflavin and ultraviolet-A (UVA) light to strengthen the cornea.
