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.

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.
Once the concrete stair treads are installed, people have a safe and permanent egress from inside and outside the structure. The standard size of a concrete stair tread is 24 or 48 inches by 14 inches with thicknesses dependent on the tread profile. These edge profiles include bullnose, wedge, square, and dropped. The bullnose profile has a thickness of two inches.
