There was a significant increase in the number of cases of presumed bacterial keratitis associated with soft CL wear over the study period from 2004 to 2007 at our institution. The significant increase in CLRU noted from 1996 to 1999 to 1999 to 2002 reported previously seems to have continued between 2004 and 2007.

Guttae may occur in the donor cornea after DSAEK, as previously seen after PK. Potential causes include problems with tissue preparation and grading, tissue misidentification, or surgical manipulation. Methods of elucidating whether there is an underlying predisposition to guttae formation in certain grafts, continued vigilance to ensure the highest-quality donor tissue, and meticulous surgical technique will be necessary as the use of DSAEK continues to grow.
