Significant variations in the drop masses of common lubricant eyedrops were identified using standard laboratory equipment. Heterogeneity in the drop volume of standard eyedrop medications suggest that potential dosage discrepancies exist, possibly altering treatment efficacy. A pre-established reference measure may lead to the production of more appropriately sized eyedrops for use in human eyes.
