Refractive reconstruction of keratoconus

Abstract

Keratoconus is a progressive disease that seriously affects the eyesight of young people. Keratoconus often causes high myopia, irregular astigmatism, and some patients with advanced corneal scar, visual acuity significantly decreased. In the course of diagnosis and treatment of keratoconus, refractive reconstruction of keratoconus is the focus of clinical attention. After years of research and exploration, a variety of treatment methods in different stages of disease(non-progressive, progressive, advanced)for keratoconus patients refractive reconstruction, so that they can obtain good visual function. This paper mainly reviews the refractive reconstruction schemes of keratoconus in different periods, analyzes the advantages and disadvantages of various treatment schemes at home and abroad, and summarizes the characteristics of different treatment methods, with a view to providing theoretical reference and new treatment ideas for the diagnosis and treatment of keratoconus.
