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.

Mentions: ICRS flatten the cornea by means of a spacer effect in which the central arc length of the cornea is decreased.2 ICRS have been shown to provide refractive stability over time and slow down the progression of ectasia.5 The authors here propose a coupling technique to provide further posterior cornea stress relief for ectatic disease. The suture-coupled Intacs segments create a 360° ring complex (Figure 1) that is inserted into standard femtosecond laser-created intrastromal channels.
