Blade Free LASIK

The No Blade technique is a  Blade Free way to creating the  LASIK flap.  The LASIK flap is a thin part of the top surface of the cornea, around 100-140 microns thick,  which the doctor folds back in order to expose the corneal tissue below, which is then reshaped by the excimer laser to correct refractive errors.  (see LASIK for more details on the LASIK procedure). Conventional LASIK involves the use of a microkeratome to make the LASIK flap. This sensitive and mechanically complicated instrument makes a high speed oscillating blade move across the eye to make the LASIK flap. While conventional LASIK is generally considered quite safe, if a problem does occur, the microkeratome is usually the reason for the problem.

The Blade Free LASIK technique, by contrast, uses a laser to make the flap, and enables your eye surgeon to create your LASIK flap without using a blade cutting across your eye.

During the Blade free LASIK procedure, femtosecond  pulses of laser light (these are really really tiny pulses, both in space and time), are focused at a plane within the cornea. These tiny laser spots convert a very tiny portion of the cornea into a gas bubble. When millions of such laser pulses are laid down within the cornea, the corneal layers get separated, thus allowing the creation of a LASIK flap.

The exact shape, size, and depth of this layer of bubbles within the cornea are determined by your doctor depending on what is ideal for your eye. All of this is computer controlled for maximum accuracy and precision-this is not possible with a conventional microkeratome with a blade. The NO BLADE flap creation process takes only 10-20 seconds per eye.

Immediately after the flap creation process, the bed on which you lie automatically rotates, and now the corneal reshaping procedure is carried out. Before the corneal reshaping process with the excimer laser, your Centre for Sight doctor easily separates the tissue where these bubbles occur, and then folds it back, thus creating your corneal flap.

When corneal reshaping is complete, a flap created by Blade Free LASIK  is uniquely able to “lock” back into place. Your eye then begins to heal. Thus your Laser Vision Correction Eye Surgery is complete.
