Wavefront (CustomCornea® - ALCON)
CustomCornea is the first FDA-approved customized laser
vision correction procedure (18 Oct 2002) that addresses
both higher- and lower- order aberrations to create truly
customized vision correction. Powered by technology designed
for NASA, the eye tracking device ensures accurate placement
of the small-spot laser beam.
This customized ablations accuracy is further enhanced shaping with the small-spot beam, 0.8mm in width. Laser beam can range from 9mm to less than 1 mm in width. It is the width of the beam that defines it as either a broad beam or small spot beam laser. When the laser vision correction was first introduced, lasers used broad beam. More recently, small spot beam was introduced. Like a wide paintbrush, broad beam lasers can cover a large amount of surface quickly but may not be precise and gradual in the shaping of the cornea
