  • Abstract
  • Look Inside

We evaluated a series of 204 eyes donated for keratoplasty for possible bacterial contamination over the foregoing 2-year period. The series includ-ed 156 eyes from Sri Lanka, 28 from inside Japan and 20 from U. S. A.

The donor eyes from Sri Lanka were preserved as whole eyeballs in a solution free of antibiotics. Bacterial contamination was found in 70%. Eyes from inside Japan were mainly preserved as cor-neoscleral buttons in a solution with 5 mg/ml of mezlocillin. Bacterial contamination was found in 20%. Eyes from U. S. A. were preserved in M-K medium supplemented with 80 μg/ml gentamicin. None showed a positive culture.

A total of 492 different genera of bacteria were isolated, of which 44 were fungi. Major contaminants were coagulase-negative sta-phylococci (17.5%) and non-fermentative gram-negative rods (34.6%).

Ocular storage solution which is standard in Japan, indicates the addition of penicillin G and streptomycin to the solution to suppress bacterial growth. Our present tests show that the majority of organisms found in the culture are resistant to both the antibiotics and to mezlocillin. Gentamicin was found to be effective for a wide range of organisms found in the present study. We recommend gentamicin as the choice antibiotics as an additive to preserving solution of eye for keratoplasty.
