Official title

Effects of Carboxymethylcellulose Artificial Tears on the Eye Microbiome: a Randomized, Controlled, Double-Blind Study

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Carboxymethylcellulose (CMC), a common component in artificial tears, has been shown to modify the gut microbiome. The study is examining its effects on the eye microbiome, which may have implications on ocular disease and artificial tear choice. The study will administer artificial tears containing CMC to the treatment group and artificial tears without CMC to the control group. Surveys and conjunctival swabs will be collected before and after treatment for bacterial genome sequencing and analyzed by R statistical packages.
