The aim of our study was to evaluate the clinical outcomes after Keraring implantation for keratoconus in patients with thin corneas. Patients and Methods Ten eyes from 10 patients with keratoconus, who underwent femtosecond laser-assisted Keraring implantation for keratoconus, were included in this retrospective study. Uncorrected visual acuity (UCVA), corrected visual acuity (CDVA), keratometric readings, central corneal thickness and thinnest corneal pachymetry have been evaluated preoperatively and 6 months after the Keraring implantation. Results UCVA, BCVA and keratometric readings improved at 6 months postoperatively. Conclusions Our data showed significant keratometric amelioration and visual improvement after Keraring implantation for keratoconus in patients with thin corneas at 6 months postoperatively.
