LASIK, or Laser In-Situ Keratomileusis, is an eye surgery that uses lasers to correct a number of common vision problems. This popular procedure aims to alter the shape of the eye lens and improve the patient’s vision, by making use of laser beams . After the surgery, patients usually achieve significantly improved or even clear vision.
If you are thinking of improving your eyesight through this surgery, here are the three things you have to know before undergoing the procedure.
Vision problems that LASIK fixes
LASIK is an example of refractive surgery. Essentially, this means that the vision problems that LASIK solves usually have to do with an incorrect path of light into the eyes. This is usually recommended for patients with nearsightedness, farsightedness, and astigmatism.
Nearsightedness is when the patient is able to distinguish objects that are near them, but struggles to see far away objects. The opposite condition is called farsightedness, in which far away objects appear clear to the patients, while near objects are blurry. Astigmatism refers to the condition wherein the vision is blurry in general, no matter the location of objects.
How LASIK Eye surgery works
With the use of precise and concentrated light or laser beams, an incision is made on the very thin covering of the eye, forming a flap and exposing the cornea. The cornea is the primary focus of this procedure because, in most vision problems, it is the shape of the cornea that needs correcting in order to properly focus the incoming light into the retina.
After making the incision, the shape of the cornea is altered according to the condition of the patient. A highly specialized laser is used to remove very small amounts or corneal tissue to achieve the desired shape.
Risks that come with the procedure LASIK surgery has a 98% success rate, which makes it one of the safest surgeries performed worldwide. However, as with all medical procedures, it also comes with several risks such as worsening of the vision after surgery. This could be due to too little or too much corneal tissue removed by the surgeon.
Most patients also experience dry eyes after the procedure, but this is mostly temporary and goes away after about two weeks.
