Abstract

Insights

Prolonging donor eye submersion in PVP iodine solution from 1 to 5 minutes significantly reduced contamination rates in eye banks. This enhanced decontamination method improves the safety of corneal transplantation procedures.

Area of Science:

  • Ophthalmology
  • Microbiology
  • Transplantation Science

Background:

  • Microbiological contamination of preservation media in eye banks is a growing concern.
  • Elevated contamination rates pose risks to the success of corneal transplantation.

Purpose of the Study:

  • To evaluate the efficacy of prolonged submersion time in polyvinylpyrrolidone iodine (PVP-I) solution for decontaminating donor globes.
  • To reduce microbiological contamination in donor corneas intended for transplantation.

Main Methods:

  • Retrospective analysis of 76 cornea donor conjunctival smears.
  • Comparison of contamination rates before and after extending donor eye submersion in PVP-I solution from 1 minute to 5 minutes.

Main Results:

  • Prior to extending submersion time, 15 of 76 donor corneas showed contamination in the preservation medium.
  • After increasing submersion to 5 minutes, no contamination was observed in the preservation medium.

Conclusions:

  • Extending donor globe submersion time in PVP-I solution from 1 to 5 minutes is an effective decontamination strategy.
  • This protocol provides a practical guideline for eye banks to enhance donor tissue safety and reduce contamination rates.

Hand hygiene

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Cleaning, Sterilization, and Disinfection

Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease.
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
