Progressive epithelial ingrowth occurred with a continuous sheet of epithelium to the flap edge. Location of epithelial ingrowth and cytokine epithelial-stromal interaction appear to be important factors in this complication. Histopathological changes in the cornea after LASIK are difficult to detect in areas with normal wound healing.
The Er:YAG laser emulsified the lens nucleus safely and effectively. These early results include a higher than acceptable posterior capsule rupture rate and reflect the surgeon's learning curve with a new technology. Effective power delivery can be achieved with sapphire- and zirconium-fluoride-based fiber optics through a silica tip. The optimal energy delivery system has not been determined.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
