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.
by Sean O'Hara on. I received a question about stair width from one of our clients and thought it made sense to clarify the typical stair design rules for houses. These are the rules that are in the 2006 International Residential Code. Stairways have to be at least 36â³ clear width above the handrail height.Handrails canât project more than 4.5â³ into each side. You need at least 80â³ of head height throughout the stair. The maximum height of a riser is 7.75â³ and the treads have to be at least 10â³ deep.Treads also need to be a minimum of 4â³ tall.tairways have to be at least 36â³ clear width above the handrail height.
