What is Intralasik?
Posted by
naileye at Wednesday, March 11, 2009
The" Intra" component denotes the use of the Intralase Femtosecond laser and LASIK is an abbreviated term for "Laser Assisted In situ Keratomileusis" With Intralasik, the first step of cutting the flap is accomplished using a highly precise laser, the Intralase Femtosecond Laser.
The Intralase software directs the Intralase 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). In an "inside out" process, 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 unseparated 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 Intralasik, surgeons can avoid the complications related to surgical blade problems. The Intralase laser precisely delivers the laser energy directly to the outer surface of the cornea, which suffers no trauma. A higher degree of accuracy in both the depth and size of the corneal flap is now possible with Intralase.

There are a number of valuable benefits that this form of surgery provides.
1) Safety
This is the most valuable advantage of Intralasik and the main reason why Optimax invested in this expensive technology. With the accuracy and safety checks offered by Intralase, 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) Avoid 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
Intralase FS60 for flap creation on IntraLasik, Custom IntraLasik and
PAC IntraLasik.
The VASTLY IMPROVED 4th GENERATION INTRALASE called the IntraLase-FS60 (femtosecond) 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.)
4th GENERATION INTRALASE-FS60 HAS VAST IMPROVEMENTS FROM LESSONS LEARNT FROM THE 1ST GENERATION INTRALASE:
• Twice as fast procedure time (usually less than 20 seconds).
• Enhanced patient comfort and safety during the procedure.
• Improved flap quality creation software.
• Smoother corneal surfaces than before, for better results.
• Administers less energy to the cornea for greater safety.
THINNER FLAPS CAN BE CREATED TO SAVE CORNEAL TISSUE!
Of course the biggest benefit of 4th Generation IntraLase-FS60 is the increased SAFETY and PRECISION from its older version of ALL-LASER BLADE-FREE procedure.

How does IntraLase-FS60 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 Intralase 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 used for Lasik)
• The process takes under 15 seconds, on average ( twice faster than the older version).
• 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.

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