To describe a case of IOL calcification after DSAEK.
Medical University of Vienna
A patient with endothelial dystrophy was treated with Descemet stripping automated endothelial keratoplasty (DSAEK) in 2009. Due to a transplant rejection episode a Re-DSAEK combined with cataract extraction and implantation of a hydrophilic IOL (Lentis-L312, Oculentis GmbH) had to be performed 6 months later. Another eighteen months later, visual acuity dropped from 0.15 to 0.52 logMAR due to a calcification of the IOL.
The IOL was explanted and sent to the University of Utah, Salt Lake City, for evaluation. The IOL showed changes typical for IOL calcification. Interestingly, the calcification was constricted to the size of the pupil.
With new methods of lamellar corneal transplantation being used more frequently, the number of anterior chamber tamponades with air/gas increases. In cataract cases in which a gas tamponade might be necessary later on (cornea guttata), hydrophilic IOLs should be omitted.
