Keratoconus Classification, ACXL Indications and Therapy Flowchart

Modern keratoconus (KC) therapeutic strategy should be based on its clinical stage depending on corneal apex and posterior elevation location (central 2 mm), curvatures, thickness, high-order aberrations, documented clinical (UCVA, BSCVA) and instrumental (topographic, pachymetric and/or aberrometric) progression [1]. Therapeutic approach must be also strongly connected to patient’s age according to different progression rate, faster in paediatric patients 18 years and under and among young people between 19 and 26 years [2].
