Intact cornea
NettetIn eyes with intact corneal endothelium, topical MMC passes through the cornea and can be detected in aqueous humor and corneal tissues. 3–5 In PRK, MMC reduces corneal haze by depleting anterior stromal keratocytes; however, MMC can also damage endothelial cells through DNA crosslinking and apoptosis. 6 High MMC concentration … NettetNonetheless, using intact corneal tissue does not allow for complete control over corneal properties. For this, technologies such as bioprinting and other forms of laboratory-made corneas offer the ability to design a …
