[The COMOD system. A preservative-free multidose container for eyedrops]
1Augenklinik, Saarbrücker Winterbergkliniken.
Background:
The newly developed COMOD -system is a multi-dose-container for eye drops which makes the addition of preservatives unnecessary. In this study we investigated the microbiological safety of the COMOD -system which was used in action for the first time.
Methods:
After cataract surgery 97 patients only used unpreserved, dexamethason-containing eye drops in COMOD -bottles for two days in hospital and for five more days at home. The used bottle were examined microbiologically afterwards.
Results:
No COMOD -bottle showed a microbiologically serious contamination; no patient showed an unusual healing process which would have been typical for any infection. Concerning the handling it turned out during use in hospital that the hand-made prototypes have to be improves. The vast majority of patients managed the handling at home well, independent of sex or age.
Conclusion:
The COMOD -system is a suitable microbiologically safe container for unpreserved eye drops.
