Persistent staining of lattice lines after intraoperative trypan blue use in patients with lattice corneal dystrophy.

Purpose: The aim of this study was to report the persistent staining of corneal lattice lines resulting from the intraoperative use of trypan blue.

Methods: This is a case series.

Results: Four patients with lattice corneal dystrophy (LCD) who underwent either deep anterior lamellar keratoplasty or cataract extraction with intraoperative trypan blue use demonstrated persistent, postoperative trypan staining of lattice lines on slit-lamp examination out to final follow-up (range, 176 to 541 days postoperatively).
