Intrastromal corneal ring segment implantation in pediatric keratoconus: Up to 10 years of follow-up

< 0.0001). No eyes lost lines of CDVA 1 year postoperatively compared to preoperative, and 74.8% of the eyes gained lines. Preoperatively, 61.7% of the eyes had a refractive cylinder ≥3.00 D; one year postoperatively, 76.6% had <3.00 D. The treatment was successful in most cases at 5-, 7- and 10-year follow-ups (84.3%, 85.5%, and 88.9%, respectively), qualified success in around 8% of the eyes, and treatment failed in 6 eyes represented a cumulative rate over the 10 years <10%ConclusionICRS implantation induced significant visual and refractive improvements, and in most eyes with available long-term follow-up, visual and refractive improvements were maintained, supporting ICRS as a long-term visual rehabilitation option in pediatric keratoconus.
