[Pigment dispersion following extracapsular cataract surgery with posterior chamber lens implantation]

Pseudophakic bullous keratopathy is the leading indication for penetrating keratoplasty. Eight cases of postoperative corneal decompensation occurred during 1 year, five of them in 1 month. So far, three of these patients have received corneal grafts. None of the intraocular lenses were removed. Common symptoms are increased intraocular pressure in the immediate postoperative period, deposition of pigment on the corneal endothelium, long-lasting folds in the on descemet's membrane, edema of the corneal stroma, pigment dusting of the iris and anterior chamber angle. The potential role of the following factors is discussed: risk factors, infection, toxic reaction to the intraocular lens, antibiotics, Epinefrin and irrigation solution. The synonym "toxic solution syndrome" is proposed and discussed.
