What is LASIK Eye Surgery?

LASIK (laser in-situ keratomileusis) is a procedure that can correct astigmatism, nearsightedness (myopia) and farsightedness (hyperopia). During this surgery, the cornea located in the front portion of the eyes is reshaped so that light travelling through it focuses properly on the retina at the back part of the eyes. In this article, we provide information about the advantages, disadvantages and risks of LASIK eye surgery, and how to prepare for it.

Benefits of LASIK Eye Surgery

  • Surveys reveal that this surgery has been successful for about 90% of patients.
  • There is negligible pain during the operation.
  • Vision correction is immediate or occurs by the next day.
  • This surgery does not require any stitches or bandages.
  • You can undergo follow-up surgery even after a few years to further correct your vision if required.
  • LASIK eye surgery can dramatically reduce your dependence on contact lens or eyeglasses, and many patients are able to become completely independent of them too.

Drawbacks of LASIK Eye Surgery

  • The results of the surgery on the cornea are irreversible.
  • It is a technically complex procedure which requires the doctor to cut the flap. Any error can affect vision permanently.
  • On rare occasions, patients may lose their “best” vision” which is the best eyesight they can obtain by wearing eyeglasses or contacts.

  • Vision problems while driving at night

How to Prepare for LASIK Procedure
First, the doctor will thoroughly examine your eyes and conduct tests to measure pupil dilation, air pressure, corneal mapping, refraction and corneal thickness. Contact lens wearers should not wear them for three days before their evaluation. The surgeon will examine your eyeglass prescription. Before going to the surgery, avoid wearing eye makeup. If you feel uneasy or unwell on the day, it is advisable to postpone the procedure.

After the LASIK Procedure
The doctor will prescribe eye drops to prevent inflammation and infection, and keep the eyes moist. You may feel a slight burning of the eyes and blurred vision for a while. Use only eye drops prescribed by the doctor. Healing is rapid and your vision will improve in a few days after the surgery. Go for follow-up visits as advised by your doctor.
