Acute corneal hydrops after intrastromal corneal ring segment implantation for keratoconus.

UNLABELLED: We present a 14-year-old boy with a history of advanced keratoconus in the left eye. Two 400 μm intrastromal corneal ring segments (ICRS) (Intacs) were implanted on the 140-degree meridian at a depth of 400 μm in the left eye using the suction-guided manual dissection technique. While the temporal segment was being implanted, a probable break in Descemet membrane occurred, allegedly opening during the hours after surgery; acute corneal hydrops was observed on the following day. We have no knowledge of an ICRS implantation case that experienced acute hydrops due to a break in Descemet membrane without perforation of the anterior chamber; ie, without allowing aqueous humor through the corneal internal incision.
