Lasik eye surgery is a refractive surgical procedure that works wonders on the eyes of people suffering from nearsightedness, farsightedness, astigmatism and presbyopia. It reduces a person's complete dependency on glasses and contact lenses. The full form of Lasik is Laser-Assisted In Situ Keratomileusis and is a procedure that involves permanently changing the shape of the cornea, the clear covering of the front of the eye using an excimer laser.
How is Lasik surgery done?
The surgery should be done with great skill as it involves the most delicate part of human body. It is done with a knife called microkeratome and is used to cut a flap in the cornea. A hinge is done at one end of this flap and then the flap is folded back revealing the stroma, which is the middle section of the cornea. Instant pulses from a computer-controlled laser vaporize a portion of the stroma and the flap can be easily replaced.
How is Lasik advantageous over other surgical procedures?
Lasik eye surgery is quite advantageous over other surgery procedures because they often involve much less pain as an aftermath. Lasik unlike other eye surgeries also promise extremely good vision that can be achieved almost immediately or at least by the next day.
What to do in Lasik eye surgery?
But before you go for the Lasik surgery, you should have a proper test done by your physician. The optician will examine your eyes to determine their health, analyze the kind of visual correction needed and determine how much Lasik ablation is required. Risks like losing vision, developing debilitating visual symptoms, severe dry eye and large refractive errors are often associated with Lasik eye surgeries. So you consult a proper eye surgeon for the best results.
Once you are confident about undergoing the Lasik eye surgery you should follow certain rules to get quick results from the surgery. Following is a brief history of what should be done before, during and after Lasik:
Before surgery
?Stop wearing soft contact lenses, rigid gas permeable lenses and hard lenses. ?Do not feel pressurized by your doctor, friends and family ?Stop using creams, lotions, perfumes and make-ups. ?Keep removing all debris and residues from the eye surfaces.
During surgery
?Apply a numbing drop to your eye that will clean the area around your eye and create a numb feeling near your eyes. ?Wear the shield that holds the flaps in places. Wear it to prevent any sudden accidents or getting hit in your eyes.
After surgery
?Consult your doctor immediately in case of any itching, eye irritation, mild pain or sudden discomfort. ?Use eye drops given by the doctor to prevent infections or inflammations. ?Never wear contact lenses at least for next fortnight.
Lasik eye surgery is hassle-free but you should take proper care for your eyes. In spite of such care, if you face any worsening symptoms you should immediately contact your doctor to prevent any further eye-related problems.
Lasik eye surgery is a medical procedure which is designed to correct a person's vision so that they rely less on contact lens or eye glasses. It has proven to be extremely successful for millions of people around the world, including over 6 million Americans. Some well known people who have had Lasik eye surgery include world champion golf Tiger Woods, signer Jessica Simpson and actor Brad Pitt.
While there are great stories about how Lasik has improved peoples' vision, the actual results can vary amongst individuals, not every one is a good Lasik candidate and there are some risks associated with the procedure that you should be aware of. However, lets start by explaining what the operation is and how it works.
The word Lasik actually refers to "Laser-Assisted In Situ Keratomileusis". A Lasik operation is conducted by a trained eye surgeon called an ophthalmologist. Assisted by a computer, the surgeon uses a laser to mould the shape of the cornea of the eye by vaporizing the tissue. The operation is suitable for many people who suffer from short-sightedness, long-sightedness and astigmatism. The whole aim of Lasik is to reduce a person's reliance on contact lenses or eye-glasses.
An actual eye laser procedure only takes around 15 minutes per eye. The patient is awake throughout the whole operation and the person can walk in and walk out of the medical facility.
The entire operation is painless. First, the surgeon cuts the cornea to create a flap. This flap is flipped over to reveal the inner center of the cornea. Using a refractive laser, the surgeon vaporizes tissue which is micrometers in thickness in order to reshape the cornea.
The cornea is essentially the lens of the eye and by changing its shape a person will be able to focus more normally. If you have nearsightedness the ophthalmologist will flatten the cornea, while if you have long-sightedness he or she will make it steeper. If you have an astigmatism the goal is to smooth the irregular cornea. At the end of the surgery the flap is placed back into its original position.
Evidence shows that serious complications arising from Lasik eye surgery is less than 1 percent, with minor complications at around 3 to 5 percent. The majority of patients will only have some discomfort for a few days following the procedure.
Not everyone is suitable to have Lasik surgery. While the various risk factors vary between individuals, generally you will have to be at least 18 years old and have both good eye and general health. By talking to a qualified Lasik surgeon you will be able to determine whether you are a good candidate for laser eye surgery for your particular set of circumstances.
If you are tired of wearing contact lens or are worried about how you look with eye-glasses, Lasik eye surgery could be the type of medical procedure that you are searching for. Make sure you talk to a qualified Lasik surgeon about your options and suitability for the operation. You may be pleasantly surprised of the end results.
