LASIK

At first, the ophthalmologist will apply numbing drops to your eye by pulling down your bottom eyelid. It takes a few seconds for the drops to work. A device is used to hold your eyelid open. This device is specially used during LASIK eye surgery. You won’t feel any pain. During the surgery, the doctor uses an instrument called a microkeratome for cutting a thin flap in your cornea. The flap is then painlessly peeled back. Your vision is blurred during this time. The doctor uses a laser for reshaping and correcting the underlying corneal tissue so that it can properly focus light onto your retina. Once the cornea is reshaped and corrected, the flap is put back in place, and the surgery is complete.

The laser used for LASIK surgery is highly specialised ; it uses a cool ultraviolet light beam for reshape your cornea.

LASIK has a 96% success rate. The majority of the patients who have undergone LASIK procedure agreed to have an improved vision. Your vision improves immediately after the procedure or might take few weeks after the procedure.

You can make further adjustments for correcting your vision if it changes with age. You can do this even if you had LASIK surgery years ago.

Most of the people achieve 20/20 vision after a LASIK procedure A very small percentage of people require a LASIK enhancement procedure, a few months after the primary LASIK surgery for achieving visual acuity of 20/20.

You might experience blurred vision, watering, or itching. These problems disappear with time. Side effects also include hazy vision; dryness of the eye, difficulty with night vision; scratchiness, halos or starbursts around lights and halos; light sensitivity; small pink or red patches on the white portion of the eye; mild discomfort or pain in the eye.

Some people (a very small percentage) might also need a second surgery. This is known as an enhancement. An enhancement helps in achieving the desired vision correction. This is more common in people who were more farsighted, nearsighted, or had higher astigmatism before they underwent LASIK surgery. In other words, people whose vision required more intensive correction might need to undergo retreatment.
