Retention of iris supported intraocular lenses at the time of penetrating keratoplasty for pseudophakic corneal oedema.

The long-term follow-up of patients undergoing penetrating keratoplasty for pseudophakic corneal oedema is reported. The cause and frequency of corneal decompensation following intracapsular cataract extraction with insertion of an iris supported lens was assessed and found to be unrelated to the implant in the majority of cases. The most common cause of decompensation was endothelial touch during the cataract extraction.
