Laser Assisted in Situ Keratomileusis (LASIK) is a proven treatment method for
corneal refractive surgery. Surgically induced higher order optical aberrations
were a major reason why the method was only rarely used to treat presbyopia, an
age-related near-vision loss. In this study, a novel customization algorithm for
designing multifocal ablation patterns, thereby minimizing induced optical
aberrations, was used to treat 36 presbyopic subjects. Results showed that most
candidates went from poor visual acuity to uncorrected 20/20 vision or better for
near (78%), intermediate (92%), and for distance (86%) vision, six months after
surgery. All subjects were at 20/25 or better for distance and intermediate
vision, and a majority (94%) were also better for near vision. Even though
further studies are necessary, our results suggest that the employed methodology
is a safe, reliable, and predictable refractive surgical treatment for
presbyopia.
