Abstract
Keratoconus is a common degenerative disorder of the cornea. This article describes new methods for the diagnosis and treatment of keratoconus. Since corneal refractive surgery is widely used, the early diagnosis and rational treatment of keratoconus have become more important. Traditional diagnosis always depends on clinical manifestations and changes in corneal topography but it cannot stop the progression of the disorder. Currently, in addition to corneal topography, a three-dimensional anterior segment analyzer, confocal microscope, ocular response analyzer, OCT and other instruments are being used to screen keratoconus or suspected keratoconus. Active, preventive treatments like corneal collagen cross-linking can stop progression. Key words: Keratoconus; Early diagnosis; Treatment; Corneal collagen cross-linking
