Surgical technique: coupling of intrastromal corneal ring segments for ectatic corneal disorders in eye bank corneas.

Moshirfar M, Hsu M, Khalifa YM - Clin Ophthalmol (2011)

Bottom Line: The management of corneal ectasia is evolving, with intrastromal corneal ring segments playing an important role in delaying or eliminating the need for penetrating keratoplasty.This paper describes a modification in the implantation technique of intrastromal corneal ring segments that allows for coupling of the two segments with suture, affording more structural support.

ABSTRACT

Two intrastromal corneal ring segments were positioned on the storage tray to simulate their position in the cornea (A). 9-0 nylon suture was passed through the superior islet of the first segment (B) then through the superior segment of the second segment (C). An 18-gauge needle was then placed between the two segments in the middle of the loop created by the 9-0 nylon, and the suture was tied with a standard knot (D).

An 18-gauge needle was then placed between the two segments in the middle of the loop created by the 9-0 nylon, and the suture was tied with a standard knot (D).

Mentions: Two ICRS were positioned on the storage tray to simulate their position in the cornea (Figure 2A). While maintaining this configuration, a 9-0 nylon suture was passed through the superior islet of the first segment (Figure 2B), then through the superior islet of the second segment (Figure 2C). Care was taken to ensure the ICRS maintained their configuration and that the suture did not cross from the superior aspect of one segment to the inferior aspect of the other islet. An 18-gauge needle was then placed between the two segments in the middle of the loop created by the 9-0 nylon, and the suture was tied with a standard knot (Figure 2D).
