The most commonly used refractive surgery procedure is the lasik eye surgery procedure and this is a very popular form of surgery that has the advantage of being less painful and resulting in a 20/20 vision in most cases, usually on the very next day.

The basic lasik surgery procedure involves an instrument which is known as a microkeratome which is used in the surgery to create a thin and round flap in the cornea. The surgeon will take the flap and fold it back so that it is not in the way and then takes away some corneal tissue that is underneath with the help of an excimer laser which uses cool ultraviolet light beams to exactly remove very small bits of tissue from the cornea in order to reform it.

Once the cornea is reformed into the correct shape it will work in an improved manner and focuses light into the eye as also onto the retina thereby getting the person to see clearly which will be better than what it was before the lasik eye procedure. Afterwards, the flap is replaced back in place and covers the area where the corneal tissue had been removed.

Corrects Nearsightedness, Farsightedness as well as Astigmatism
Lasik surgery procedure is helpful for nearsighted as well as farsighted people. In the case of nearsightedness the aim is to flatten the extra-steep cornea and with farsightedness, a steeper cornea is required. Excimer lasers are also used to rectify astigmatism through smoothening of the irregular cornea and getting it into a more normal shape and the lasik eye procedure will help to achieve this.

There are certain steps to follow before getting your lasik eye procedure performed and these include choosing a good surgeon, finding out whether you are the right person for this type of surgery as well as finding out whether you have any dry eye diseases which need to be treated and cleared prior to the lasik eye procedure.

There are different types of lasik eye procedures such as blade versus bladeless and also custom lasik or wavefront lasik procedures. The wavefront-guided lasik eye surgery procedure makes use of 3-dimensional measurements that figures out how the eye processes images and this is helpful for guiding the laser in reshaping the front portion of the eye that is called the cornea. The wavefront measurement of the lasik eye surgery procedure is extremely useful in extreme and precise individualized vision correction.

Lasik Eye surgery is a surgical process that is aimed at reducing a person’s dependency on glasses or contact lenses. The article provides basic information on LASIK eye surgery.

LASIK (Laser-Assisted In Situ Keratomileusis) surgery permanently changes the shape of the cornea, the clear covering of the front of the eye, using an excimer laser. A flap in the cornea is cut using an special knife called microkeratome. A hinge is left at one end of this flap. The flap is folded back revealing the stroma, the middlesection of the cornea. Pulses from a computer-controlled laser vaporize a portion of the stroma and the flap is replaced. This is just one of the techniques of Lasik.

Lasik Eye Surgery: Is this the right time? Examine your eyes with your eye doctor to start with. You must be in good general health and should be over 18 years of age. You should not have any eye diseases of concern like cataracts or glaucoma. Laser vision correction can treat a very broad range of nearsightedness, farsightedness and astigmatism.

Does the Lasik eye surgery hurt? Is it painful? The surgery may be a bit uncomfortable for a few patients. One good way to learn more about how it might feel is to talk to someone who has had the procedure, such as a friend or relative, or a staff member at the doctor’s office. Most of the times, its just the fear of the unknown. Anesthetic drops are used to numb the eye just before surgery begins and you may be given a mild sedative. After your procedure, your eye may feel a foreign body sensation or irritation for a few hours, but most patients are quite comfortable after taking a short nap. You will be given drops for your eyes to counteract the potential dryness you may experience for several days following the surgery.

Recovery period after Lasik Most Lasik patients usually see quite well the day following their procedure and may be able to resume most of their normal daily activities, but patients with higher prescriptions may recover more slowly. Although the speed of visual recovery depends on personal healing patterns, most patients notice dramatic visual results within the first few days following their procedure.

What are the risks from Lasik surgery? There are very few risks with the laser vision correction procedure. However, the chances of having a vision reducing complication have been documented in a number of clinical studies to be minimal. Do not forget that millions of people have had excellent results from laser vision correction.

It has become easier to get treated for any disease easily these days, all thanks to the advent of information technology along with the advancement of medical science. However, getting operated for some treatment leaves people with many apprehensions, especially when the vital organs like eyes are in question.

The doctors at the lasik eye surgery center will offer you treatment for eye diseases and conditions like myopia – a condition in which things that are at quite a distance, become blurred or indistinct, but things that are approachable can be viewed easily and clearly. The other condition, hyperopia is characterized by clear vision when viewing objects in the distance but blurrs vision up close. Lasik surgery is also effective for astigmatism, which is a distortion of the image as reflected on the retina. This is caused by a misshapen cornea or lens of the eye. In fact, the combination of these conditions is common and can be cured easily at any good and reliable lasik eye surgery center.

In fact, if anyone who wishes to undergo the lasik surgery wears contact lenses, then it is advisable to stop wearing them before the initial check-up. The center will ask to you not to wear contact lenses for at least two weeks before surgery, as they are capable of altering the shape of the cornea. The doctors from the center can choose a treatment from a variety of procedures that suit the eye condition. However, wavefront mapping method is generally used prior to the surgery. Lasik treatment is not advisable for pregnant or nursing women or people with various conditions like corneal scratching or infection, keratonconus, herpes simplex or herpes zoster, glaucoma or high blood pressure, inflammation of the eye or eyelid and crusting of the eyelashes.

If you suffered from any visual problems before your surgery other than distance viewing conditions, it is important to remember that the surgery is not expected to correct any of those conditions that were pre-existing. While lasik eye surgery is quite safe, there is always the slight risk of complication. Hence, it is important to consider these risks before going for or deciding on the procedure. And that is what the lasik eye surgery center does, by giving you factual points involved in the lasik surgery.
