PURPOSE: To describe the outcome of complete intrastromal ring (MyoRing, DIOPTEX GmBH, Linz, Austria) implantation following intrastromal corneal ring segment (Intacs, Addition Technology, Inc., Sunnyvale, CA) implantation for severe keratoconus.
METHODS: Case report.
RESULTS: A MyoRing was implanted in a keratoconic patient who had undergone a previous Intacs implantation surgery 4 years previously without Intacs explantation and had residual refractive error. There were no intraoperative or postoperative complications. After 1 year; mean keratometric power decreased from 50.3 to 43.6 diopters, uncorrected distance visual acuity improved from 20/400 to 20/50, and corrected distance visual acuity improved from 20/200 to 20/30.
CONCLUSIONS: In selected severe keratoconus cases with high myopia and steep keratometry previously treated with Intacs implantation, if significant residual refractive error is observed, secondary implantation of MyoRing over Intacs may improve vision and refraction.
