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. © 2007 by Lippincott Williams & Wilkins, Inc.
