How LASIK Laser Eye Surgery Can Cure Your Nearsightedness

LASIK laser eye surgery is a complex surgery procedure used to treat all degrees of nearsightedness. The physician who performs it uses a small knife to cut a flap of the cornea, then removes part of the underneath tissue with a laser and put the flap back in its place.

In LASIK eye surgery, the skills of the physician or surgeon are more important than in the PRK procedure, where the computer does most of the work. This is the reason why it is mandatory to find a high-skilled and experienced surgeon who has done several such procedures before to perform it. The success of this procedure depends mainly on the doctor.

Advantages Of LASIK Eye Surgery

Most physicians agree that this kind of eye surgery is very appropriate for correcting very severe vision problems. It also allows a faster recovery than PRK and other procedures. In addition, patients who have undergone a LASIK laser eye surgery can see accurate enough to drive and read within just a week or so.

Does LASIK Laser Eye Surgery Have Risks?

For a limited number of patients, LASIK laser eye surgery can have some negative side effects, which include over or under-correction, scarring of the cornea, astigmatism, corneal infections, lower contrast sensitivity or problems with driving at night.

LASIK Laser Eye Surgery versus PRK & RK

There are physicians that still consider other surgical procedures as well. Some patients who had previously decided on LASIK laser eye surgery are often advised to undergo a so called PRK or RK procedure instead. After studying all the options they have and consider the possible side effects, many of them eventually agree on other methods.

Many clinical centers, while they do perform LASIK laser eye surgery in many situations, they claim that other procedures or methods are in some cases more suitable. For instance, some physicians believe that for a small number of patients with low or moderately nearsighted eye conditions, a RK (radial keratotomy) is more appropriate.

RK is an earlier eye correction surgery procedure that does not need an Excimer laser. The incisions are made radically along the exterior portion of the cornea with a hand-held scalpel. Such procedures are intended to help reshape the curvature of the cornea and allow light rays that enter the eye to focus properly on the retina. The success of the method depends on the length and number of these incisions. Some surgeons use this type of eye surgery for a small number of people with a disorder called mild myopia.

In contrast, other physicians and surgeons consider LASIK laser eye surgery as the best option whatsoever. While they do mention other options to their patients, such as PRK or RK, they don't recommend them in favor of these procedures.

Other doctors claim that a RK procedure involves penetrating around 90 percent of the cornea, which can have negative impacts on the structure of the eye. Furthermore, once you have undergone a RK surgery, you can never repeat it or have a PRK. This is the reason why some physicians would never suggest this method to anyone.

LASIK Eye Surgery: A Definition

The word LASIK means ?Laser-Assisted In Situ Keratomileusis.? In situ is latin and means to deal with a phenomenon in place where it occurs, as opposed to outside of it?s environment. Keratomileusis is a surgical improvement of the refractive state of the cornea. It is performed by lifting up the front surface of the eye by forming a thin hinged flap, under which the shape of the cornea is changed by using some type of surgical device.

Excimer Lasers

LASIK eye surgery is therefore surgery that is done in order that a person who wears glasses or contact lenses should no longer be completely reliant on them to see. It is a medical procedure undertaken by a qualified opthamologist. The aim is to modify the shape of the cornea (the clear covering of the front of the eye) through use of an excimer laser. An excimer laser is a type of ultraviolet chemical laser that is unusually well focussed and capable of highly delicate control. Instead of burning away or cutting materials, an excimer laser intrroduces sufficient energy to disrupt molecular bonds of surface tissues. Effectively the tissue disintegrates in a controlled fashion through ablation rather than burning. Excimer lasers can remove very thin layers of surface material with almost no heating or change to the material which is left behind.

Flap Creation

When LASIK surgery is performed, a knife known as a microkeratome is inserted into the cornea and cuts a flap of skin. A human cornea measures from around 500 to 600 micrometres in thickness; the microkeratome creates a 100 to 200 micrometre thick flap. At one side of the flap is left a small piece of skin known as a hinge. The flap of skin is then gently folded back to show the stroma (otherwise known as the middle area of the cornea).

There are two types of microkeratomes currently in use, mechanical and laser. Both are affixed to the eye by use of a 360 degree vacuum ring, flatten the cornea with a clear plate, then cut the cornea underneath the plate.

Mechanical microkeratomes use a sharp thin metal blade. Laser microkeratomes are used in the IntraLasik procedure. They employ amplified light energy to form thousands of minute bubbles at a predetermined depth. These bubbles of water and carbon dioxide connect with each other create an incision.

Reshaping the Stroma

A laser that is controlled by a computer is then used to disintegrate a part (but not all) of the stroma and after that is finished, the flap of the cornea is fixed up and put back into place. New and more advanced ways of performing LASIK surgery are being looked at all of the time.

The purpose of eyeglasses and contact lenses is to compensate for the weaknesses of the eyes and to allow for vision that is as clear as can be. LASIK is a form of refractive eye surgery that is geared towards improving the eye?s ability to focus and not just focus, but also focus well on any object. When it comes to LASIK surgery, a laser is used to remove part of the tissue of the cornea and then it is reshaped in order to improve its ability to focus.

Are You A Bad Candidate For Lasik Eye Surgery?

Lasik eye surgery is not the right thing for everyone. Although there are many individuals that can see remarkable improvement with eye surgery, some are just not the right candidates for the job. That?s because of the eye conditions or the risks that they face. The eye surgeon that you are working with will talk with you specifically about your actual benefits versus the risks of lasik. They will also tell you if you even are a person that can consider having lasik eye surgery at all.

Some of the reasons why lasik eye surgery may not be right for you include these.

? If you are talking medications like steroids or medications that will limit the healing that your body can do, you may not qualify.

? If the costs are too high and you simply do not have coverage with your insurance company, you too may be limited.

? If you have an autoimmune disease or some other type of major illness or chronic condition, you may not qualify. This will depend on what condition you have.

? If you have a prescription for glasses that is quite strong, have a prescription that changes often, or you have a need to wear your glasses only some times, you may not qualify.

? If your career depends on your eye sight, you may want to consider your options closely.

? Your eye?s physical condition may also make a difference. Things like the pupil?s size, the amount of tear production that you have as well as the corneal thickness that you experience, all matter.

Although many individuals are the perfect candidate for lasik eye surgery, others have other conditions that stop them from having lasik performed. Your doctor will work with you to determine your level of risk and ability to have it before making any promises to you.
