Lasik is a form of eye surgery that permanently changes the shape of cornea (covering formed on the front of eye). The lasik surgery in India is done to improve the vision in order that people has to lean less towards glasses or contact lenses. Whereas, following image is the proof that how many of them are dependent on optical glasses.
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.
The procedure starts with creating a flap of cornea tissue. This flap is peeled off so that the excimer laser can reshape the cornea tissue underneath. In ancient times, when Lasik was done, it happened with the help of a special knife that was used to cut the flap. In today’s generation more different types of lasers (femtosecond) are used to create the flap of cornea. Once reshaping is done, doctor replaces and protects the flap, and here no stitches are needed. Moreover, cornea will naturally keep the flap in hold.
