Unlike LASIK, the doctor does not create a corneal flap.
The corneal flap will be softly moved and will start to cure immediately.
You must avoid the instinct torub your eye as this will likely dislodge the corneal flap.
The corneal flap is then softly relocated and will begin to cure immediately.
Quick: The entire process of creating the corneal flap with all-laser LASIK takes about 30 seconds.
Rather than a microkeratome,Z-LASIK uses the Ziemer Femtosecond Surgical laser to create the corneal flap.
Your surgeon will create a corneal flap using an alcoholic solution, rather than a surgical laser.
Z-LASIK is a technique that uses a special laser to create the corneal flap, rather than a microkeratome.
Instead of creating the corneal flap with a femtosecond laser, the doctor will use a precise surgical blade called an epikeratome.
However, only procedures that use the IntraLase® laser for creating the corneal flap can be considered all-laser LASIK.
When creating the corneal flap, FemtoLASIK uses the Carl Zeiss(Germany) VisuMax Femtosecond laser instead of the conventional microkeratome blade.
Z-LASIK- commonly referred to as the“ALL-Laser LASIK” technique because the corneal flap is created using a special femtosecond laser.
The thinner corneal flap decreases recovery time because the natural bandage can heal much faster when compared to a thicker flap. .
A suction ring set on your eye just before making the corneal flap may cause a feeling of pressure, and your vision may dim a little.
Both involve lifting the extremely thin epithelium to access the deeper corneal tissues,instead of creating a thicker corneal flap as in LASIK surgery.
However, the complete healing of the corneal flap may take up to a year or so, and the healing period may vary from one patient to another.
These pulses are very rapid and create separation in the layers of the cornea,creating the corneal flap, without the use of a micokeratome.
In this way, he or she can create an extremely precise corneal flap and tailor your treatment based on the smallest variations in the structure of your eye.
By using this method, thousands of bubbles are precisely positioned side by side causing the corneal tissue to separate-the result is a corneal flap of exact diameter, depth, location and hinge position.
With All Laser Micro-LASIK®, corneal flaps are almost 50% thinner than flaps created by other microkeratomes and as thin as laser-created flaps. .
The hinged flap made in LASEK surgery is created in the epithelial layer of the eye andis much thinner than the corneal flap created in LASIK(which contains both epithelial and deeper stromal tissues).
This is when the corneal flap, which was cut out during surgery, acts as a natural bandage and the cornea is healed- the healing time after LASIK surgery.
LASEK also may be a better option if you have a high degree of myopia(which requires more tissue removal from the central cornea to correct the refractive error), or if your occupation or hobbies puts you at high risk of an eye injury anddislodging the corneal flap created in LASIK surgery.
The laser-created corneal flap is gently opened to provide Dr. Lin access to treat the stroma with the chosen laser and correct your vision(Stage 2: Laser Treatment).
With this technology,the surgeon can program the desired depth and position of the corneal flap into a computer system prior to actual surgery, making the creation of the flap an incredibly safe and accurate procedure.
The Custom Micro-LASIK® technique creates an ultra-thin corneal flap during laser eye surgery in order to gain access to the corneal stroma for laser treatment. Currently, Custom Micro-LASIK® utilizes a specially-designed microkeratome or a femtosecond laser to create an 80-110 micron flap that is almost 50% thinner than traditional flaps and preserves more corneal tissue strength, which allows laser treatment of patients with higher prescriptions and thin corneas.
Step one is to cut a flap of the corneal cap and lift it up and away.
The surgeon then pulls back the flap to expose the underlying corneal tissue, and then the excimer laser ablates(reshapes) the cornea in a unique pre-specified pattern for each patient.
But instead of completely removing and discarding this tissue, as in PRK,the LASEK surgeon pushes an ultra-thin"flap" of epithelium off to one side of the cornea, where it remains attached to the eye(like the thicker flap of corneal tissue created during LASIK surgery).
