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.

f4-opth-5-1439: Confocal microscopy of keratoconus showing the deep stress lines in the posterior stroma.

Mentions: In a study of keratoconus using confocal microscopy, Hollingsworth and Efron concluded that the clinical sign of Vogt’s striae is indicative of collagen lamellae under stress.7 The authors have noted the same phenomenon on confocal microscopy of keratoconic corneas with stress lines intersecting at the center of the cone (Figure 4). The depth of these tension lines explains why ICRS segments work best when they are implanted deep within the stroma. The relief of the posterior lamellae may also explain why ICRS have been shown to slow progression of ectasia.5
