Everyone wants to have a clear vision. The basic rule for a clear vision is that the eye's cornea and lens must refract the light rays properly. This basic rule allows all images to be focused on the retina. If not, the images will be seen blurry. This blurriness has its own name: Refractive error. The reason for refractive errors is the difference between the shape of the cornea and the length of the eye. The main types of refractive errors are myopia (nearsightedness), hyperopia (farsightedness), presbyopia (loss of near vision with age), and astigmatism.

What is LASIK eye surgery? LASIK (laser-assisted in situ keratomileusis) is a very popular laser eye surgery to treat myopia, hyperopia, and astigmatism.
It is a new generation of laser eye surgery, conducted by an ophthalmologist to improve the eyesight of patients and in many cases – to allow patients to get rid of the glasses. During LASIK eye surgery, a flap in the eye’s outer layer (epithelium) is created. The surgeon folds back the flap, then removes some corneal tissue underneath by the help of the laser. Then the flap is placed back, where the corneal tissue was removed.
