We describe a case of corneal ectasia in a patient with previous radial keratotomy (RK). The uncorrected distance visual acuity (UDVA) was 20/400, the corrected visual acuity (CDVA) 20/50, and the spherical equivalent (SE) −5.125 diopters (D). Corneal topography revealed inferior corneal ectasia with corneal astigmatism of 9.2 D. Six months after corneal collagen crosslinking (CXL), the UDVA improved to 20/200, the CDVA to 20/40, and the SE to −4.625 D. Corneal astigmatism was reduced to 8.7 D. An add-on IOL was implanted to correct the residual cylindrical refractive error (−9.25 × 60; Torica-sPB IOL, Humanoptics), after which the UDVA improved to 20/32, the CDVA to 20/30, and the SE to −0.50 D. This case is the first to document the efficacy of CXL in corneal ectasia as a complication of primary RK in a nonkeratoconic or a keratoconus-suspect eye with an add-on IOL used to correct the residual refractive error.Financial DisclosureNo author has a financial or proprietary interest in any material or method mentioned.
