All-Laser-Lasik

What is All-Laser-Lasik?

In this procedure, the first step of creating flap is using a highly precise laser, the Femtosecond Laser.

The software directs the Femtosecond laser to optically focus its beam into a tiny, 1 micron (.001mm) spot of energy that passes harmlessly through the outer layers of the cornea until reaching its exact depth within the stroma (central layer of the cornea). The laser beam creates a separation plane by forming an interconnecting series of bubbles made of carbon dioxide and water vapor.

The laser beam stacks a pattern of bubbles along the periphery of the treatment plane, leaving an separated section of tissue to act as a hinge. As with a traditional LASIK approach, the surgeon then folds the tissue back to expose the underlying corneal layer to prepare for the excimer laser treatment that will re-shape the cornea. With All-Laser-Lasik, surgeons can avoid the complications related to surgical blade problems. The Femtosecond laser precisely delivers the laser energy directly to the outer surface of the eye, which suffers no trauma.

There are a number of valuable benefits that this form of surgery provides.

1) Safety

This is the most valuable advantage of All-Laser-Lasik and the main reason why Optimax invested in this expensive technology. With the accuracy and safety checks offered by Femtosecond laser, major complications do not occur.

2) Precision

Flap measurements are highly accurate. This provides the surgeon with confidence to:

a) Treat patients previously rejected because of thin corneas.

b) Reduce the risk of ectasia - a complication that can occur from an unexpectedly thick flap. In ectasia the cornea is thinned beyond the margin of safety resulting in instability.

c) No induced changes in refraction which can occur with irregularly thick flaps from LASIK affecting visual outcome.

3) Outcomes

By being able to cut the initial flap in such a controlled fashion, we are able to closely predict our results. In creating such precise and uniform flaps we avoid surprises of new astigmatism and aberrations.

Technology

The VASTLY IMPROVED FEMTOSECOND MACHINES has been introduced at Optimax, Malaysia to create BLADE-FREE LASIK flaps. (The conventional alternative is when the LASIK flap was created using a microkeratome with a blade.)

How does FEMTOSECOND Laser Work?

• Pulsing at a speed of one-quadrillionth of a second, the laser uses an infrared beam of light to prepare the flap.
• The Femtosecond has pulses that are focused within the tissue to create an incision below the surface of the corneal tissue.
• A series of closely-spaced bubbles of 2-3 micron in diameter each, is created, which are absorbed into the tissue and leave a cavity in the stroma. (Hence the tissue above created is the flap)
• The process takes under 15 seconds, on average.
• The surgeon then lifts the flap to proceed with the Excimer Laser sculpting.
• The surgeon can precisely control laser specifications for flap diameter, depth, and edge angle.

BENEFITS OF FEMTOSECOND LASER

Of course the biggest benefit of Femtosecond laser is the increased SAFETY and PRECISION.

• Enhanced patient comfort and safety during the procedure.
• Smoother corneal surface for excellent visual outcome.
• Improved flap quality.
• Thinner flaps for tissue saving.
• Rapid healing & visual recovery.

In short there is no longer any worry about irregular or non-perfect flaps for Lasik!
