For a vision to be clear, your eye’s cornea and lens must refract the light rays in a proper order. This helps and allows your eye to recognize and distinguish between object and the images. The images focus on retina; if it does not work so, then image which you see may get blur. This blurriness in the vision is termed as “refractive error?, which is commonly caused by difference in between the curvature and the length of the image.
Lasik uses an ultraviolet laser to get rid of small amount of cornea tissue. This gives cornea a new shape so that light rays are focused mainly on the retina. Lasik helps cornea to be thinner. It is an outpatient surgical procedure which hardly takes 10 – 15 minutes to perform for an individual eye. Anaesthesia is used in the form of eye drop that numbs the eye surface. Lasik is a procedure which can be done on more than one eye at a same time.
