In all-laser or bladeless LASIK for corrective eye surgery, lasers have replaced mechanical cutting tools (microkeratome) associated with conventional LASIK.
Instead, bladeless LASIK uses two different kinds of lasers:
- Femtosecond laser: This laser directs laser energy precisely to create a thin, hinged flap, which then is lifted temporarily from the eye’s surface or cornea.
- Excimer laser: Energy from this type of laser is applied to the newly exposed eye surface, where tissue is removed in a precise pattern to alter the cornea’s shape.

How Bladeless LASIK Works
The LASIK surgeon uses computer software to guide the femtosecond laser beam, which applies a series of tiny bubbles within the central layer of the cornea. The resulting corneal flap is created at a precise depth and diameter pre-determined by the surgeon.
As occurs with a mechanical microkeratome, a small section of tissue at one edge of the flap is left uncut, forming a hinge that allows the surgeon to fold back the flap so the cornea can be accessed and reshaped for vision correction.

What Happens After?
Recovery is similar to that of traditional LASIK. Following surgery, some people (as with traditional LASIK) have reported feeling eye irritation for up to two days.
Study results have shown that a bladeless procedure may produce a lower incidence of dry eye after LASIK. Fewer enhancement (“touch-up”) procedures seem to be required when bladeless LASIK is performed. But Dr. Bley says that thin flap microkeratome LASIK also now has a lower incidence of dry eyes.
Bladeless LASIK – Safer than LASIK
The laser is much better at making a flap that is of uniform thickness and precision. It remains thin near the edges where we want most to preserve the strength of your cornea. The edges stick down more firmly, again adding more strength. This is a safety advantage for bladeless LASIK.
The precision of the lasers allows me to make your flap thinner, leaving more of your eye untouched, again with the extra strength. This allows the doctor to undercut the flap edge, making, you guessed it, the edge of the flap stronger.
