Refractive Error Correction - Lasik Eye Correction Surgery
A refractive error is an error in the focusing of light by the eye and a frequent reason for reduced visual acuity. There are normally three main types of refractive errors: Myopia(nearsightedness), hyperopia(farsightedness) and astigmatism. Myopia is a refractive defect of the eye in which collimated light produces image focus in front of the retina when accommodation is relaxed; hyperopia is a defect of vision caused by an imperfection in the eye, causing difficulty focusing on near objects; astigmatism is eye condition where rays that propagate in two perpendicular planes have different foci. All of the three errors are caused by the out of shaped cornea of the eye. Therefore, based on the cause, researchers work out an effective way to correct those errors: Lasik Eye Correction Surgery.
Lasik accomplishes to correct vision with the help of a laser controlled by a computer. The surgeon would first create a tiny flap on the cornea, and then with the flap lifted, the surgeon apply the laser to remodel the cornea into a normal shape. Finally, the flap will be repositioned.
