Lasik Surgery - Know Utility Of It!

Dr.Nikhil Nasta · Accepted Answer

LASIK is a corrective eye surgery that aims at repairing vision impairment. It is known as laser in situ keratomileusis. This surgery is typically used to fix nearsightedness, farsightedness and even astigmatism. So can this surgery help in removing your spectacles and giving you crystal clear vision? Let us find out!

Definition: The LASIK procedure basically works towards reshaping the cornea, which is the clear portion that coats the eye. This is responsible for proper travel of light to the retina where it must focus in an appropriate manner so as to reach the back of the eye.

Corrective Technique: With its cornea reshaping technique, this procedure is effective in correcting vision and removing spectacles for at least 96% of the patients who go through this treatment.

Convenient: LASIK surgery is a highly convenient one that hardly creates any pain. Numbing drops are used to minimise the pain that may be felt during the procedure. Also, the time taken for the correction is very little with most procedures commencing within a day or two. Further, this procedure does not require any bandages or stitches and usually works with a powerful laser beam.

Eyeglass Dependence Reduction: Most patients have a dramatic improvement in the quality of their vision and do not require glasses, while other patients usually have a reduced dependence on eyeglasses once the surgery is done.

Preparing for the Surgery: To prepare for the surgery, it is imperative to meet and coordinate the details with the eye specialist of the ophthalmologist who will examine your eye care and seek to determine the risk of any kind of side effect. Also, the doctor will ask specific questions regarding the medical history of the patient before conducting the surgery. As a part of the preparation, the doctor will also take measurements of the corneal thickness and other such factors like refraction, corneal mapping, pupil dilation and air pressure, so as to carry out the surgery in the most effective manner. Do not wear your contact lenses for at least three weeks before this evaluation so as to get the correct reading which will make the surgery much more effective due to the correct settings applied to the pulses.

Procedure: During the procedure, an instrument known as a microkeratome laser will be used to lift the flap of the cornea which will be peeled back while the corneal tissue is reshaped. Then the corneal flap will be put back in its position.

Remember to be prepared for some amount of dryness in the eyes once the surgery is over. Talk to your doctor about other side effects.
