ABSTRACT: PURPOSE: To assess the prevalence of microfibre contamination in the anterior segment during and after cataract surgery and to evaluate the use of polymer-based disposable materials in ophthalmic operating theatres in Germany and Switzerland.
ABSTRACT: METHODS: A web-based survey was distributed to senior ophthalmic surgeons across hospitals, private clinics, and surgical centres in Germany and Switzerland. The questionnaire collected data on professional background, use of disposable versus reusable materials, and observations of microfibres intra- and postoperatively. Descriptive and comparative analyses were performed using Excel and chi-square testing with p < 0.05 considered significant.
ABSTRACT: RESULTS: Of 226 contacted surgeons, 184 (81%) were reached and 38 (21%) completed the survey. Most respondents (76%) were department heads or chairholders, and 68% had > 20 years of professional experience. Disposable, polymer-based textiles were used by ≥ 87% of respondents for surgical clothing, drapes, and table coverings. Microfibres in the anterior chamber were observed intraoperatively by 89% and postoperatively by 87% of surgeons. The estimated relative frequency was > 0.1 - 5% of eyes in most cases. Microfibres on or within instruments were reported by 71% of participants. Observation frequency correlated significantly with higher personal surgical volume (p < 0.03) and with senior institutional position (p < 0.02), but not with years of experience or total institutional case volume. Instrument reprocessing method (in-house vs. external) and the use of reusable irrigation/aspiration handpieces were not associated with increased microfibre observations.
ABSTRACT: CONCLUSIONS: Microfibre contamination of the anterior segment remains a frequent finding in contemporary cataract surgery despite the near-universal adoption of polymer-based disposable textiles. Further studies are needed to characterise the material composition of intraocular fibres and identify their sources to reduce this complication.
