What is a microcheratom?

Lasik is an abbreviation that means laser in situ keratomileusis , surgery that corrects myopia. The operation uses two devices, an ultraviolet laser and a microcheratom, a surgical tool with an oscillation blade. This exact shaver is used to reduce the thin slices from the cornea, the transparent outer layer of the eye that covers the iris and the pupil.

During the procedure, the suction ring is administered around the cornea, which holds it in place and creates the right pressure needed for the operation. The microcheratom then moves along the tracks on the side of the ring and cuts the flap in the cornea. Once the cornea is open, the laser is used to transform the cornea by removing the tissue to repair the vision axle. After removing the appropriate amount of tissue, the flap is placed back down, where it corresponds to the new shape of the cornea.Rraquer and was designed on a carpentry aircraft. The device was used to surgically correct visual vision, but the results were unpredictable and the first surgical methods using the oneThe instrument could not gain popularity. The development of lasers to be used in conjunction with a microcheratoma is much more accurate and has become the most popular method of myopia repair.

There are two types of microcheratomas; Mechanical and laser. The mechanical version has an oscillation blade that can move 12,000 revolutions per minute (RPM). The blade is connected to a rotating shaft, which in turn is connected to a gas or electric turbine. The blade can be moved either manually or mechanically. It is extremely important that the pressure is kept on the eye during this procedure by a ring and that only sharp blades are used to remove any negative side effects.

Thverze E Laser uses light energy to create bubbles under the cornea at a preset depth. Thousands of these bubbles are formed to create a cut. One of the benefits of a laser unit is that there are no blades that should be nA substitute, and the precision of the cut does not depend on the stable hands of the surgeon. Mechanical and laser products are accurate, but the laser unit seems to bring more consistent results and thinner cuts. A microchero with one -time use with disposable components has been developed that produces a thinner flap similar to those created by the laser version.

In some cases, postoperative complications may occur and several of them are associated with a flap. Fortunately, all such complications are treatable and can be repaired in a short period of time. Some eye surgeons migrated from the use of a mechanical microcheratom in favor of using two lasers and hoped to eliminate the complications with the valve and achieve a thinner and more consistent cut. However, Traditional Microcheratome is still a popular choice with many eye surgeons, but because of its long results and lower costs.
