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.
A standard number of treads in a stair between first and second floors is 14. One hundred-five divided by 14 equals 7 1/2 . That means the distance from the top of each step to the top of the next step will be 7 1/2 inches. With a riser height of 7 1/2 inches, tread width (run) should be at least 9 inches. Ten inches is a more comfortable run; when you multiply 7 1/2 inches by 10 inches, you get 75 -- within the conventional ratio of 72 to 75 inches. With 14 10-inch treads, the total run of the stair will be 140 inches.
