Titel | Clinical evaluation : Intrastromal Corneal Rings Segments and corneal ectasias |
Abstract Nr. | 3013 |
Doel | To report the visual and refractive results and safety outcomes of intrastromal corneal ring segment (ICRS) using mechanical implantation in patients diagnosed with keratoconus (KC) and pellucid marginal degeneration (PMD). |
Methodes | In this retrospective uncontrolled study, 131 eyes of 108 patients diagnosed with corneal ectasias were treated with Keraring-Intrastromal corneal ring (Mediphacos, Brazil). All ICRS were implanted by a mechanical procedure between 2009 and 2017. Uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BCVA), refractive data and complications were assessed with a median follow-up time of 12 month (range 1 to 79). |
Resultaten | Overall, UCVA significantly improved from logMAR 0.97 ± 0.42 to 0.50 ± 0.36, and BCVA changed from 0.34 ± 0.18 to 0.16 ± 0.14. The postoperative follow up showed a statistically significant improvement in the refractive parameters compared with the preoperative data. In this series we had no intraoperative complication, 1 eye developed infection 1 week after implantation and late extrusion of the ring segment was seen in 8 eyes. |
Conclusie | Implantation of ICRS is a safe and minimally invasive procedure leading to significant improvement in visual acuity (both UCVA and BCVA) in patients with ectatic disorders. Our results suggest its benefits are sustainable with time. |
