Information on LASIK eye surgery
Introduction
LASIK is currently the most commonly performed safe, predictable and effective laser procedure to correct myopia, astigmatism and hyperopia (far-sightedness) worldwide. According to an estimate, over 13 million people have undergone LASIK laser eye surgery in North America over the last 20 years! People are choosing LASIK laser vision correction to reduce their dependency on glasses and contacts and regain an active lifestyle. The letters L-A-S-I-K are shorthand for the full name of the operation, which is Laser Assisted In Situ Keratomileusis. While LASIK isn't a cure-all, it is the state-of-the-art treatment for certain types and degrees of vision correction.

What is LASIK?
LASIK is a type of laser surgery that can correct certain types of "refractive errors", the reduced ability to focus (or "refract") light.

Who can benefit from LASIK?
LASIK can treat:
  • Nearsightedness (myopia)
  • Farsightedness (hyperopia) and
  • Astigmatism
  • With monovision (a form of treatment for presbyopia), LASIK can also correct presbyopia, the farsightedness that develops with age.

Hence, LASIK procedure is suitable for basic vision errors such as nearsightedness, farsightedness and astigmatism.

Who performs the LASIK?
Only an eye surgeon or ophthalmologist can perform the LASIK surgery. He or she will assess your suitability for LASIK, taking into account your test results and needs as a patient.


What does LASIK do?
Your cornea at the front of the eye holds the greatest focusing ability of the eye. Laser eye surgery uses a cool beam "Excimer" laser to gently reshape the cornea, improving its focusing ability and removing the need for corrective eyewear. The entire procedure is completed within a matter of minutes.

What happens during LASIK procedure?
Before LASIK, anesthetic drops are applied, which have the effect of numbing your eye. During LASIK, two simple steps are performed by your eye surgeon:
An automated mechanical surgical blade is used to cut a thin hinged corneal flap which is then folded aside. However, "bladeless" procedures are also now readily performed in which a small flap is created on the surface of the cornea using blade free IntraLase technology or a precision surgical instrument called a microkeratome.
2. A computer-controlled laser beam is then applied onto the underlying corneal bed to change the shape and thickness of the cornea, thereby eliminating myopia, astigmatism or far-sightedness. Your Surgeon then places the flap back down and your eye begins to heal.

Possible side effects of LASIK

Symptoms related with night vision:As a temporary side-effect, you may see glare, halos or starbursts around lights at nighttime, for example while driving. Occasionally these symptoms can interfere with normal activities. But usually, they are not significant and resolve within 3 to 6 months as your eyes heal.
Dry eye:While your eye is healing, its normal system for producing moisture is temporarily disrupted. This often causes your eyes to be dry for a time after surgery and may cause fluctuating vision for some time. For most patients, the symptoms are mild and temporary. Artificial tears and other treatments can protect your eyes while they are healing.

What are some major benefits of LASIK?
The key benefits of the LASIK procedure are:

Better quality of vision:LASIK can, in many cases, improve the quality of both day and night vision. The laser is capable of treating people with larger pupils and is better for night time vision quality. It also minimizes the risk of night time glare and haloes. It results in a corneal shape that is closer to the normal curvature of the natural eye, providing better quality for both day and night vision

Increased accuracy and safety for better results: Advanced LASIK methods remove 20%-30% less corneal tissue, which is healthier and safer for the eye. Advanced methods of LASIK are also particularly beneficial for patients with thinner than average corneas, larger pupils and higher prescriptions.

Simple, short procedure:The entire procedure takes about 10 minutes. LASIK patients experience less post-procedural discomfort than others, and both eyes can be treated simultaneously.

Faster, rapid recovery:A rapid recovery time, usually within 48 hours. Most patients say they have no pain during LASIK and most can return to work the next day.

Comfort & convenience:Little or no post operative discomfort is observed in most cases and almost all patients undergoing LASIK are able to a normal, healthy life afterwards with improved vision.
