Why does it take time for the vision to fully recover following LASIK?
A smooth, central epithelium is crucial for clear vision. Following LASIK, although the epithelium is present, it may be slightly irregular and needs time to become perfectly smooth again. • How do I keep my eye open during the procedure? The eye is held open by a speculum, a smooth micro-clamp which is inserted under the eyelids. The eye is numb so one does not feel the need to blink. • What if I can’t stare at the fixation light during the laser treatment? The VISX Star S3 excimer laser automatically tracks your eye movements during treatment. • What keeps the flap down following the procedure? The first effect that helps the flap stick is called capillary action (similar to putting a piece of cellophane on a drop of water on a window). Following this, the flap is subjected to a suction gradient across the cornea, created by the endothelium, which is constantly pumping fluid out of the cornea. During the first 24 hours, the flap edges heal over, restoring more strength. And finally,
