[Standardizing the clinical diagnosis and treatment of keratoconus in China].

Keratoconus, which can lead to blindness, is an eye disease characterized by thinning and protrusion of the cornea. Keratoconus often begins during teenage with an incidence rate of about 1∶2 000. As no consensus on the diagnosis and treatment of keratoconus has never been reached in China, many doctors have not acquired a systemic knowledge of the diagnosis and treatment methods, thus various misunderstandings and problems in the clinical diagnosis and treatment of keratoconus still need our attention. By explaining the necessity and principles in the diagnosis and treatment of keratoconus, this article points out that clinicians should make efforts to comprehensively master the methods of clinical diagnosis and treatment of keratoconus and then provide patients with the most suitable treatment according to their different conditions, which are of great importance for the patients to maintain better visual acuity and quality of life for a long period.
