Once keratoconus comes on, it can't be completely cured, and its lesion is irreversible. The goal of all treatments is to prevent its further development and improve its vision to some extent. At present, the commonly used clinical treatments are as follows:
Cross-linking of corneal collagen can effectively prevent or slow down the development of keratoconus, and can improve vision to a limited extent. At present, the most mature treatment for keratoconus has a clinical history of 20 years, and the longest clinical follow-up is 7 ~ 10 years. For details, please refer to some problems of riboflavin crosslinking and the news that corneal crosslinking is safe and effective after 7 years.
RGP, a kind of hard contact lens, can improve the vision loss caused by irregular astigmatism in patients with keratoconus, but it can't stop the development of cone.
CISIS, a corneal ring implantation technique, can effectively prevent or slow down the development of cones and improve vision. Its clinical history is about 10 years, and it can only be operated in Europe at present. For details, please refer to what is the legendary Olympic ring? .
Corneal transplantation is the only treatment for keratoconus after advanced edema.
