Lasers Are Really Here And Not Just From Some Science Fictions

The lasers employed in the Lasik eye surgery is one of the most amazing offshoots of technology. One cannot help but feel awe at the uses of these lasers in modern medicine as it helps millions of people regain their eyesight.

Excimer lasers have been designed especially for doing Lasik eye method. Not all lasers have equal capability. The FDA has accepted all of the lasers now in use, but some people, prefer one method over the others. The difference in the methods lies in their manner of sending the beam to the eye and the monitoring of the eye's movement.

Lasers are generally classified into two: broad beam and scanning. Scanning is further classified into two sub- groups the slit into two sub- groups the slit scanning and spot scanning.

Broad Beam Lasers

The broad-beam laser uses a wider size rays to make incisions on the cornea, ranging from 6 to 8 millimeters to 8 millimeters. Utilizing these lasers essentially cuts the procedure time of the surgery. As such, use of these lasers reduces the risk of overcorrection due to pupil movement. However, the wider diameter of these rays caused complications; however since the improvement of the method, the risks have been virtually removed.

Slit Scanning Lasers

Slit scanning lasers project arrow like emissions in doing Lasik procedure. The ray is connected to a turning gadget with holes to broaden the part that has to be incised. The rays scan traversing the holes. Slit scanning lasers gcreate a more consistent beam and smoother incisions than broad-beam lasers. However, there is more probability to "overcorrect" when using a slit scanning laser.

Spot Scanning Lasers

Spot scanning lasers are also known as "flying spot" lasers. These lasers use a small ray measuring just about 0.8 to 2 millimeters.8 to 2 millimeters. During the surgery the beam searches the cornea transversely to do incisions. Spot scanners are able to make a very smooth cut. They are also able to produce tailored-fit incisions to treat severe astigmatism.

Eye-Tracking

Various lasers also bear an eye-monitoring system, which connects the eye position to the surgery. If this system will not be utilized, the patient will have to try to fix his sight on a distant object keep the eye completely motionless throughout the entire process.

There are two various kinds of eye tracking systems. One is called the open loop tracking which is a video based monitoring system which keeps tabs of the eye's position. If the eye moves out of position based on the programmed position, the procedure is automatically discontinued.

Another form of tracking system is called the "closed loop". This method allows tracking of the eye's position and automatically adjusting its setting keeping up with the changes in the eye's position.

Majority of the Lasik surgeons are in agreement that use of a gadget to monitor positional changes of the eye is important, especially if the procedures will take some time. Understably so because it will be almost impossible for the patients to hold their gaze for an extended period of time until the procedure is done.

IntraLase Lasers

Majority of surgeons as well, employ Intralase lasers in their Lasik eye surgery. The IntraLase laser can make incisions to make a flap to expose the cornea for reshaping. This laser is able to precisely make patterns of small overlapping spaces. The laser emission pulses very rapidly at a speed of quadrillionth of a second. The laser beam aims at the tissue and splits it at a molecular level. This method eliminates the use of high temperature or strong force on the tissue.

The IntraLase laser beam method uses special computer software to help direct the laser beam. This software directs the beam to make a series of very small bubbles on the middle level the cornea. This will create a flap in the cornea with a precisely established measurements. Using this software in operations has given hope to people with thin corneas to be qualified for the procedure.

For some, laser beams might look like some fictitious powerful gadgets created for fiction. But this is in reality an outstanding technology made available to us today. With the various methods of lasers that can be used for Lasik surgeons, they now have to capability of making the dreams of millions of people to get their sights back to normal.
