Clear corneal graft overlying the seton tube to facilitate laser suture lysis

To reduce hypotony and shallowing of the anterior chamber after seton implantation.

The silicone tube is ligated with an 8-0 nylon suture and a clear corneal graft placed over the tube to facilitate postoperative laser suture lysis.

Laser suture lysis has been performed in 34 cases to date with a follow-up period of up to 26 months. No severe complications occurred after laser suture lysis.

This technique provides another option to increase drainage postoperatively without the risk of releasable sutures or instrumentation within the eye.
