Microplastic Pollution In Eye Drops: Investigating Microplastic Contamination In Disposable And Multi-Use Artificial Tears
AI summary Read the abstract
Researchers investigated whether disposable and multi-use artificial tear eye drops contain microplastic contamination, raising concerns about direct ocular exposure to plastic particles through a product applied directly to the eye.
ESCRS seeks to promote and support research in the field of intraocular lens implantation and refractive surgery and the dissemination of the useful results thereof. ESCRS has over 7,000 members from 130 countries world-wide.

Microplastic contamination in commercial eyedrop products: detection and characterization study
AI summary Read the abstract
This study detected microplastics in 81% of 21 commercial eyedrop products tested in Malaysia, with polystyrene being the dominant polymer and lubricant eyedrops showing the highest contamination levels. Researchers estimate that lubricant eyedrop users in Malaysia may collectively be exposed to up to 2.7 million microplastic particles daily, highlighting an overlooked route of direct human ocular exposure.
Microplastic entry into the ocular surface through eye drops usage
