Since being FDA approved in the 1990s, LASIK has changed a lot.
In the early days of laser vision correction, refractive surgeons (ophthalmologists who perform LASIK) used a one-size-fits-all procedure to reshape the cornea based on averages.
Custom LASIK is very different. Custom LASIK utilizes wavefront technology – which NASA used to produce near-perfect telescopic lenses – to produce similarly awesome accuracy in the cornea. The procedure is fully customized to each patient’s eye(s), and it can be used to treat nearsightedness, farsightedness, and astigmatism.
