Descemet detachment after femtosecond-laser-assisted placement of intrastromal ring segments in pellucid marginal degeneration.
We report the case of a 46-year-old man with pellucid marginal degeneration who had uneventful placement of Intacs intrastromal corneal ring segments (Addition Technology) in the left eye because of poor best spectacle-corrected visual acuity and contact lens intolerance. The IntraLase femtosecond laser (IntraLase Corp.) was used to create the channels for the 2 ring segments. Initially, there was subjective visual improvement and the Intacs segments were well positioned. One week after surgery, corneal edema secondary to a large inferior Descemet membrane detachment was seen. The Intacs segments were removed, and an air bubble was placed in the anterior chamber. The Descemet detachment did not resolve, and penetrating keratoplasty was eventually performed.
