Managing corneal ectasia prior to keratoplasty

The advent of refractive surgery allowed for great advances in the understanding of pathophysiology, diagnosis and treatment of corneal ectatic diseases. The different associations that highlight the importance of this range from the need for early diagnosis in the screening process of candidates for laser vision correction to the impact of refractive surgery technologies on treatment. Keratoconus is still an indication for corneal transplant, and it is expected that about 5–20% of the patients may require it. However, considering technological advances, the current treatment options are diverse and can be customized to each case. This review overviews the fundamental knowledge related to corneal ectatic diseases management and its management prior to keratoplasty. Whereas this is an area of dynamic development of scientific knowledge, we present fundamental concepts, along with information on the most recent studies and future prospects.
