ABSTRACT
PURPOSE:
To evaluate microbiological cultures of cataract surgical devices and products that were reused for multiple cases.SETTING:
Aravind Eye Hospital, Pondicherry, Tamil Nadu, India.DESIGN:
Prospective cohort study.METHODS:
Samples from multiple surgical instruments and products that were reused for consecutive cataract surgeries underwent bacterial and fungal cultures and were monitored alongside positive controls for 7 days. This included instruments that were processed using immediate use steam sterilization (IUSS) between cases (e.g., surgical cannulas, syringes, phacoemulsification and coaxial/bimanual irrigation and aspiration (IA) tips, phacoemulsification and IA sleeves) (Group 1), instruments that were used without sterilization between cases (e.g., phacoemulsification tubing/handpieces, coaxial IA handpieces) (Group 2) and the residual (unused) fluid from balanced salt solution bags after being used for multiple patients (Group 3).RESULTS:
3,333 discrete samples were collected from all 3 product groups that were reused across multiple patients. In all collected samples, no bacterial or fungal growth was observed. Of the 3,241 cataract surgeries that utilized reused and IUSS-sterilized instruments alongside instrument sets cultured on the same day and balanced salt solution bags shared across multiple patients, no eyes developed endophthalmitis over a 6-week follow-up period.CONCLUSION:
Bacterial or fungal growth was not found in extensive microbiological cultures of IUSS-sterilized ophthalmic surgical instruments, and cataract surgical products that were reused in multiple patients. This microbiological data complements clinical endophthalmitis data from 2 million consecutive cases at the Aravind Eye Hospital, suggesting that their instrument and surgical supply processing practices may allow for safe and sustainable ophthalmic care.
