Influences of methylcellulose on corneal epithelial wound healing.
We performed a study to evaluate the influence of methylcellulose (MC) on the corneal epithelial wound healing. A precise epithelial wound 2.0 mm in diameter and 70 microm in depth was created by an excimer laser on the cornea of a pig's eyeball. After treatment, the eyeballs were cultured in the incubator and perfused with TC-199 medium into the vitreous cavity. Topical MC with eight different combinations of concentrations and viscosities for experimental groups and BSS for the control group were applied on the epithelial defects three times. Wounds were evaluated 24 hours later with fluorescein stain and recorded with a scoring system. All of the experimental groups except one showed a more statistically significant superior wound-healing rate than the control group. MC possesses the effect to accelerate corneal epithelial wound healing.
