What is the percentage of patients receiving Uncorrected Visual Acuity of 20/20 or better?
This depends on the refractive error to be treated. 96% of individuals with Myopia or shortsightedness less than -10D, can achieve 20/20 vision following LASIK. Nine out of ten of those with high levels of astigmatism (up to 6D) and myopia can also expect to achieve 20/20 vision. For those individuals with hyperopia or long-sightedness the results are similar, those with low to moderate levels of hyperopia up to 94% achieving 20/20 or better.
