Abstract Details


To study if intracorneal ring segment implantation is an effective and safe method of visual improvement in patients with keratoconus and to evaluate the long-term clinical outcomes after Keraring implantation for keratoconus in patients older than 40 years.


Corneoplastic Unit at the Queen Victoria Hospital, East Grinstead, UK


Eleven eyes from 11 patients with keratoconus who underwent femtosecond laser-assisted Keraring implantation for keratoconus were included in this retrospective study. The uncorrected visual acuity (UCVA), corrected visual acuity, keratometric readings, central corneal thickness and thinnest corneal pachymetry were evaluated preoperatively and 6 months after the Keraring implantation.


UCVA, BCVA and keratometric readings improved at 6 months postoperatively.


Our data showed significant keratometric amelioration and visual improvement after Keraring implantation for keratoconus in patients older than 40 years at 6 months postoperatively.
