Abstract Details


To report clinical results and safety profiles of Kerarings, (Mediphacos, Belo Horizonte, Brazil), implantation in eyes with moderate to severe keratoconus.


Royal Eye and Lasik center, Cairo, Egypt


Interventional case series of 30 eyes from 20 patients implanted with Kerarings using the femtosecond laser. Evaluation included uncorrected (UDVA) and corrected distance visual acuity (CDVA), manifest refraction, and Placido-based Scheimpflug imaging. Postoperative follow-up was 1 day, 1 week, and 1, 3, and 6 months.


This prospective study evaluated 30 eyes of 20 patients with a mean age of 27 years. The mean logMAR of UDVA was significantly better 6 months postoperatively than preoperatively (0.54 ± 0.15 versus 1.50 ± 0.23) (P<.001), as was the mean logMAR of CDVA (0.13 ± 0.07 versus 0.85 ± 0.16) (P<.001). The mean spherical equivalent refractive error was -5.43 ± 1.76 diopters (D) preoperatively and -2.42 ± 0.95 D at 6 months postoperatively (P<.001). The mean preoperative corneal astigmatism was, 7.21+/- 2.78 D and at 6 months postoperatively 2.99 ± 1.09 D (P<.001).


Implantation of Kerarings for moderate to severe keratoconus is safe and effective, leading to significant decrease in myopia and appreciable decrease in astigmatism with improvement in CDVA.
