Custom LASIK is an individualised laser vision correction treatment that is wavefront-guided. With the Custom LASIK procedure, nearsighted, farsighted and astigmatic individuals have the potential to achieve a new level of vision. Custom LASIK uses wavefront-guided technology to measure unique imperfections in the eye. The technology then produces a treatment for the eye and the information is transferred to the laser. The doctor then uses that information to fine-tune the procedure thereby providing a new level of precision and accuracy.
