Abstract
Gentamicin is the most widely used antibiotic in the decontamination of donor cornea for penetrating keratoplasty. However, the incidence of resistance to gentamicin is on the rise. Bacterial isolates from 178 donor corneal rims were studied for gentamicin sensitivity. The overall rate of gentamicin resistance was 63.4%. At 86.2% the Pseudomonas. species had the highest rate of resistance, followed by Streptococci at 84.6%. The high rate of gentamicin resistance encountered by us and others suggest that either addition of a second antibiotic to corneal storage media or replacement of gentamicin by an antibiotic with a broader spectrum of activity may help reduce the risk of endophthalmitis following penetrating keratoplasty.
