LASIK surgery has been the vision correction procedure of choice for decades. However, a fairly recent development in LASIK surgery now offers patients more options. Bladeless, also called all-laser LASIK surgery, uses a laser, as opposed to a blade, to make the corneal flap necessary for the procedure.
To better understand LASIK, it is best to explain that LASIK is a two step process. LASIK is a type of laser vision correction surgery called “lamellar refractive surgery” because it is performed between the layers of the cornea. Step one of the laser vision correction process involves the creation of a “flap”. A LASIK flap is a circular strip of the outer corneal tissue dissected away from the underlying corneal layers but left attached in one segment called the hinge. The most common location for the hinge is either the nasal (on the side) or the superior (upper) position. The LASIK flap is necessary in order to expose the deeper corneal layers to the excimer laser energy that reshapes your cornea to improve your vision.
The procedure for bladeless LASIK surgery is similar to that for traditional LASIK surgery. However, instead of using the microkeratome blade to create a corneal flap, your doctor will use computer software to guide the femtosecond laser beam and create a corneal flap with a precise depth using millions of microscopic air bubbles. The corneal flap created by the laser has a precise structure and shape that improves how well the flap stays in place. The doctor calculates the depth of the bubbles in the computer software with the data he/she receives from your preliminary evaluation.
LASIK procedures with a blade have a low incidence of complications. However, on extremely rare occations, a blade can create a flap with uneven edges, which can result in abnormal corneal surfaces. Rare incidents of vision-threatening scars can also occur after LASIK has been performed with a blade. With bladeless LASIK, infrared lasers create the corneal flap. The laser divides tissue at a molecular level and works rapidly to create corneal flaps that have more defined and better angled edges, resulting in fewer complications.
Available to More Patients
Previously, patients with thin corneas or dry eyes were not candidates for LASIK surgery. However, due to bladeless technology, many more patients are now candidates for LASIK surgery.
