During Custom LASIK, a laser is used for a bladeless procedure. First, instead of the microkeratome blade that was used in traditional LASIK, the FDA-approved femtosecond laser is used to create a flap with laser energy, allowing customization of the flap. The femtosecond laser is capable of creating extremely precise flaps of uniform thickness by producing tiny bubbles inside the cornea that are 1/10,000 of an inch in diameter. The laser beam cannot penetrate into the eye beyond the cornea, and therefore is extremely safe. After the flap is created, an excimer laser is used to reshape the cornea in order to reduce farsightedness, nearsightedness, or astigmatism. The flap is returned to its original position, and seals itself without sutures.
Custom LASIK is performed as an outpatient procedure that takes approximately 10-15 minutes. With the precision that the femtosecond laser provides, some patients who were once considered unsuitable for LASIK due to thin corneas may now be suitable candidates. Furthermore, research has shown that more patients achieve vision that is 20/20 or better with femtosecond custom LASIK as compared to other methods. Therefore, Columbus Ophthalmology only offers their patients the best: bladeless, custom/optimized LASIK with a femtosecond and excimer laser.
