Abstract:
The possible causes of intraocular infections after microsurgical operations on the eye are discussed. Extensive experiments were carried out to investigate infection caused by the patient himself, by the surgeon and by the surgical surroundings. To consider the different aspects involved in "perioperative prophylaxis", we examined the preoperative, intra- and postoperative periods. Conjunctival diagnostics, disinfection of the conjunctival sac, and the operating area were investigated for the preoperative period. Microbiological examinations were carried out to check the possibility of contamination of eye drops, the operating theatre equipment, and of microscopes, etc. The sterilization of microsurgical instruments using different procedures was checked in particular. During the intraoperative period surgical clothing like face masks, gloves and gowns were examined. Sterile sheets for the patient, including an analysis of the respiratory air under the sheet, were monitored. The results are evaluated with respect to their significance for perioperative prophylaxis and the practical consequences for optimal prevention of infection.
Insights
Preventing intraocular infections after eye surgery requires rigorous perioperative prophylaxis. This study examines patient, surgeon, and environmental factors to optimize infection control strategies.
Area of Science:
- Ophthalmology
- Microbiology
- Surgical Sciences
Context:
- Intraocular infections pose a significant risk following microsurgical eye operations.
- Understanding the sources of infection is crucial for effective prevention.
- Perioperative prophylaxis encompasses multiple stages of surgical care.
Purpose:
- To investigate the causes of post-microsurgical intraocular infections.
- To evaluate the effectiveness of various prophylactic measures across preoperative, intraoperative, and postoperative periods.
- To identify practical strategies for optimal infection prevention in ophthalmic surgery.
Summary:
- Examined preoperative conjunctival diagnostics, disinfection, and environmental contamination (eye drops, equipment).
- Assessed intraoperative factors including surgical attire and patient draping, analyzing respiratory air.
- Investigated the sterilization efficacy of microsurgical instruments using diverse methods.
Impact:
- Provides evidence-based recommendations for enhancing perioperative prophylaxis protocols.
- Aims to reduce the incidence of intraocular infections, improving patient outcomes.
- Contributes to the knowledge base for sterile surgical practices in ophthalmology.
