About the Treatment
LASIK can be defined as a surgical process that involves a laser to correct nearsightedness, farsightedness, and astigmatism. In a LASIK surgery, a thin flap is created in the cornea by making use of one among the two, i.e., a femtosecond laser or a microkeratome blade. The flap is folded back, and then some corneal tissue underneath is removed by the surgeon using an excimer laser. After this process is complete, the flap is placed back in its original position, which covers the site where the corneal tissue was removed. In the case where a person is suffering from nearsightedness, the goal of the LASIK performing surgeon is to flatten the highly-steep cornea; in the case of farsightedness, the surgeon desires a steeper cornea. Moreover, in the case of astigmatism LASIK can be performed to correct the problem by smoothing and bringing back the cornea to a regular shape.
