To report refractive, topographic, and visual outcomes 12 months after same-day treatment with corneal cross-linking (CXL) and Ferrara intracorneal ring segments (ICRS) in eyes with progressive keratoconus (KC) and contact lens intolerance.This was a case series of 7 eyes (7 patients) with progressive mild to moderate keratoconus and contact lens intolerance undergoing implantation of Ferrara ICRS immediately followed by corneal cross-linking. Uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), refractive error, pachymetry, and keratometry were evaluated at 3, 6, and 12 months of follow-up.Mean follow-up was 11.7 ± 3.6 months (range, 5–17 months). Mean preoperative UCVA and BSCVA were 0.10 ± 0.07 (range, 0.05–0.2) and 0.56 ± 0.08 (range, 0.5–0.7), respectively. One year after the treatment, mean UCVA and BSCVA measured 0.60 ± 0.24 (range, 0.32–0.9) and 0.82 ± 0.25 (range, 0.5–1.2), respectively. The mean spherical equivalent decreased significantly (P < 0.05) with 3.5 diopters (D). Mean K values (average keratometry of the cornea) decreased from 46.81 ± 2.13 D (range, 44–51 D) to 43.97 ± 2.22 D (range, 42–47.5 D) 1 year after the treatment. The average preoperative thinnest pachymetry measured 462 ± 46 μm (range, 410 ± 546 μm) and did not change significantly after the treatment. In patient 1, the inferior ICRS was removed 5 months postoperatively because of implant migration.The combined treatment of corneal cross-linking and Ferrara ICRS is a safe procedure that may be considered in patients with progressive mild to moderate KC and contact lens intolerance.
