Latanoprost Free-Acid Release from Tested Commercial Contact Lenses after 24 Hours.

n = 6, Mean Standard Deviation. Concentration of latanoprost were measured using EIA.
No-Cell Model: Cell culture inserts (PET membrane) without cells, Monolayer Model: PET insert with a monolayer of human corneal epithelial cells, Multilayer Model: PET insert with a multilayer of human corneal epithelial cells (stratified culture).
†The release as a percentage of uptake has been calculated based on the ratio of the released concentration over the sorbed amount.
#Significantly different from other contact lens materials (silicone hydrogel) .
*Significantly different from the amount released by respective materials in the no-cells model .
