title: Intrastromal corneal ring segment implantation with the femtosecond laser in a post-keratoplasty patient with recurrent keratoconus.
abstract: A 50-year-old woman had implantation of intrastromal corneal ring segments for recurrent keratoconus 15 years after penetrating keratoplasty. Two segments (0.15 mm and 0.25 mm) were inserted without any intraoperative or postoperative complications, using the femtosecond laser to create the tunnels (superior and inferior). Ten months after the procedure, the uncorrected visual acuity was 20/100, compared with counting fingers preoperatively, and the best spectacle-corrected visual acuity improved from 20/63 to 20/32. Although the results are encouraging, the long-term effect of this approach for the management of post-keratoplasty patients with recurrent keratoconus is not known.
