New technique of intracorneal ring segments suturing after migration.

PURPOSE: To describe a new technique for suturing of the intracorneal ring segments to stabilize it in the proper location and to prevent recurrent displacement of the ring.

METHODS

Two patients with recurrent ring segment migration toward the incision were treated with this new surgical technique between 2010 and 2013. The first case had Intacs ring (Addition Technology, Fremont, CA) and migration occurred 2 months after implantation. The second case had Keraring segment (Mediphacos, Belo Horizonte, Brazil) and migration occurred 1 week postoperatively. The ring segments were fixated to the cornea with a 10-0 nylon suture through the channel. The suture was removed at 1 month postoperatively.

RESULTS

Ring segments remained in the desired location with a follow-up period of at least 6 months after implantation.

CONCLUSIONS

This newly described ring suturing technique is an effective procedure that can be used to treat ring segment migration in the channel.
