Figure 1

Decision tree treatment considering the stability or progression, the corrected distance visual acuity (CDVA), and the refractive error. PRK = photorefractive keratectomy; pIOL = phakic intraocular lens; IOL = pseudophakic intraocular lens; ICRS = intrastromal corneal ring segments; CXL = corneal collagen cross-linking. If keratoconus is stable after ICRS implantation.
