Lasik eye surgery involves treating vision irregularities like farsightedness, nearsightedness, and astigmatism with the help of a laser. The process is painless and takes less than 15 minutes. A surgeon uses a tool like the mickrokeratome to create a feather thin flap in cornea without affecting the epithelial skin layer. This flap is then removed to expose the inner cornea stroma, which is then reshaped accordingly with the use of a laser.
