THE PROCEDURE 
The cornea is first measured by a computerized corneal topographer, which measures approximately 15,000 points on the cornea and draws a topographical map in 3-dimensions accurately showing the exact shape of the cornea from centre to edge in all directions. This map is subsequently used to design the person's lens, to determine if the cornea is modified accurately by the lens and to monitor the molding effect over time. The lens works by applying positive and negative pressures to mold the corneal shape to achieve the desired result.
