    Eye Operations Using Laser Eye Surgery

    Vision problems and refractive errors such as nearsightedness (nearsightedness), farsightedness (farsightedness) and astigmatism (distorted vision) can be corrected using the laser surgery procedure. These problems are related to the way the eyes focus on images on the retina, the photosensitive part of the back of the eye. Also an important factor in the ability of the eyes to focus is the shape of the cornea, a clear front surface of the eye.

    Eye Operations Using Laser Eye Surgery


    In laser eye surgery, a laser device is used to change the shape and contour of the cornea. An excimer laser is often used for this procedure; this produces ultraviolet light that vaporizes unwanted tissue. This procedure will change the contour and shape of the cornea, thus correcting minor and moderate refractive errors.

    In kraff eye, the doctor removes the outer layer of the cornea (epithelium) with a surgical blade. Then, a computer-controlled laser beam is used to cut and vaporize the cornea tissue. It usually removes enough tissue to change the shape of the cornea, resulting in better vision. The healing process for this type of procedure is usually from 5 days to 1 week.

    LASIK surgery involves creating a flap on the cornea using a blade or laser; it is known that this procedure is much more complicated and more complicated. The laser is then used to vaporize tissue within the cornea; this will improve your shape, leading to good vision. After removing enough tissue, the valves will return to their original position. In this case, healing will be faster than PRK.


    LASEK is a variation and combination between PRK and LASIK. The outer layer of the cornea is cut and weakened by alcohol so that it can be lifted whole. The laser beam is then used to remove tissue below the epithelium, as with PRK. After the laser procedure is completed, the epithelium returns to its place and heals. It usually takes about two weeks to cure and it is recommended to correct minor eye problems.
