Bacterial contamination rate of eyedrops: comparison of a hospital and a private outpatient center in Kermanshah, Iran.

Bacterial contamination rate of eyedrops: comparison of a hospital and private outpatient ophthalmology centers of Kermanshah, Iran. Eye drops are sterile solutions with different clinical effects. Like any therapeutic medication, they should be administered using aseptic technique and stored in a way that prevents bacterial contamination. In our hospital and local private clinical settings, some cases of bacterial keratitis are thought to be due to eyedrops, which are used on multiple patients and at some point become contaminated. This study was done to compare the bacterial contamination rate in an educational hospital with private ophthalmic centers and attempt to identify the route of contamination and consequently, a method to resolve or reduce the problem.
