Gentle pulses of the cool light laser then flatten the shape of the cornea to focus light rays on the retina for clear vision. Finally, the flap is returned to it's original position, for a quick natural recovery. The flap of the cornea is replaced in the same way as for myopia.
Refraction refers to how a lens, such as a cornea, bends light rays.
When the cornea is shaped either too flat or too steep, light rays will not converge on the retina, resulting in vision that is out of focus. This improves the refractive error of nearsighted, farsighted, and astigmatic eye. There is a small chance of infection during the healing of the cornea, which is greatest during the first 3 days to one week.
