LASIK, laser-assisted in-situ keratomileusis, eye surgery is eye procedure that corrects given vision problems so there is no need to use eyeglasses or corrective lenses. The surgery is the most common of refractive eye surgery and changes shape of the cornea located in front of the eye.
This kind of laser eye surgery bends or refracts light rays to focus on the retina rather than any other point beyond or short of the retina. The main goal is to fetch you sharper and clearer vision. If you are living in Sydney then you can look for best LASIK Eye Surgery Sydney.
When it can be done
LASIK eye surgery can be done with vision problems like nearsightedness or myopia, farsightedness or hyperopia and astigmatism. Myopia occurs when the eyeball is longer that is normal or when the cornea is sharply curved hence light rays are focused in front of retina blurring distant vision.
When you have myopia you will see close things clearer, but not those at a distance. Hyperopia on the hand occurs when the eyeball is shorter than average or the cornea is too flat; hence light focuses behind the retina and not on it. In astigmatism uneven flatness or curving of the cornea disrupts near and also distant vision.
One of the best ways of reducing the risks that are associated with LASIK is to find a doctor that you can trust in qualification, skills and experience. It is also important to remember that there are health conditions that increase the risks. Find out the state of your health beforehand and be absolutely sure that you need a laser eye surgery.
