The epithelial flap is repositioned and a bandage soft contact lens is worn for 3-4 days to minimize discomfort and to protect the epithelium. The method is less invasive than LASIK and appears to give rise to fewer complications. LASEK is an acronym made from the following italic letters 'laser assisted epithelial keratomileusis'. See photorefractive keratectomy; pachometer. Want to thank TFD for its existence?
Stair Tread (Run) Length: 10 Inches Minimum Translated: This means that the horizontal distance from the edge of the stair to the back part where it stops (called the riser) should be at least 10 inches long.
Winder staircases. While both the winder-type stair and the spiral stair have a curved direction of travel, the requirement for each is substantially different. Winder stair treads are treated similar to the typical stair tread in terms of rise and run: 7-3/4 inches is the maximum tread rise. However, the nature of the winder staircase says that its shape will be narrower on the inside edge, leading to a pie-shaped tread.
