Laser Eye Surgery

Laser eye surgery increasingly popular everywhere. The more people who lasering their eyes, that can appear without glasses or contact lenses. In addition to the purpose of beauty, some people want to free from obligation in using glasses because of the professional demand, like photographer and sportsman.

Many clinics in the Netherlands and abroad that offers laser eye package. To entrap consumers sometimes eye clinic abroad offer package laser eye accommodation plus tickets and lodging costs at the hotel with a price that is almost the same as in the Netherlands. Laser eye is quite safe, although not without risks.

There are many different techniques of laser eye. Below I will explain in brief 2 laser method for aberration refraction the most often used in the Netherlands (Lasik and Lasek).

Usually, laser eye safe. But many people do not know that the risk can be large also. A brother my good friend in Bali, the eyes was blind after get laser eye surgery. This has not been long in the Dutch television reports have impressions about laser eye failed.

Laser

Laser energy is the strong (-ray beam) that can be directed exactly as straight and flat on a small object. Diameter of the beam diffraction is very small, so that it can be used as a scalpel. Use of the laser is applied in the medical world and the various tools (such as a CD or DVD).

Preparation

To be able to undergo laser eye, you should consider a few things. In general, the steps are as follows: check the list of indemnity health insurance or your confirmation prior to your insurance company if they are willing to pay the cost of your laser eye. If not, you must provide a lot of money (in most clinics cost more than € 4000, for a pair of eyes). Request a brochure and price list of laser procedures in some clinics.

In the Netherlands and abroad also have a large difference in price for the same operation and maintenance after surgery. Please count the total price you must pay for full treatment (in all) and the cost of after service (warranty). To inform the clinic of the year how much they offer a warranty when complications occur.

After that you are looking for a good eye doctor (a lot of experience with the laser), who works in the eye clinic (clinic that the success is assured and use the latest tool). This is not easy, but the combination is essential to obtain satisfactory results. Take more time and attention you to search for information!

Finally you must choose a method of laser eye you want. Risk of Lasik and Lasek action more or less the same.

Reading Glasses

Until this has not been possible with the help of laser eye (eye surgery refraction) to help you be free from reading glasses.

The user can select the reading glasses with the help of wave action electromagnetic (CK = Conductive Keratoplasty), action without surgery or the use of laser rays. With the help of this technique the dependence on reading glasses can be reduced and even eliminated altogether.

Eye

The eye is a ball which consists of various layers. In principle, the corrections made on the surface of the cornea and / or on the epitel network. On the laser eye action for people with refraction aberration (refraction aberration is the long eyeball axis deviation or refractive media aberration that far into the causes of myopic, dioptric, and cylinder).

Before Surgery

Eye clinic usually only accept patients from the age of 18-55 years, sometimes up to 60 years also for the actions of LASIK. People with a stable eye (size glass eyes have been stable for 1 year) and the spectacled size + 3.5 (farsighted) to minus 6 dioptric can do laser eye. Each clinic has different health requirements.

Let your eyes initially get a quick scan; action is free in many clinics. If the results of the test is good and you can undergo laser eye, then the clinic will ask for your choice of laser methods. After that they will explain the procedures. Laser process itself short (up to 2 minutes per eye), and you do not need to Inpatient.

Lasik (assited laser in situ keratomileusis) Action

Laser LASIK eye action with action that is most applicable in the world. Tools equipped with the latest laser a eyetracker (pursuivant eye movement).

The first stage of LASIK is the sign in the middle of the cornea and the placement of a ring around the cornea so that the eye can not move. After it was created lamina (flap) on the cornea. At the next stage flap is then opened so that the laser rays can be worked on in the cornea.

Correction was conducted with the laser to change the surface of the cornea. After irradiation is complete, the flap is put back exactly in the place and time in 3-5 minutes will flap attached itself without the need to be sewn.

Cornea can be healed completely, but will not recover as before the laser process! Flap remains attached to the cornea. This place can remain the weak point. Duration irritation (and pain after the laser) is usually shorter action of LASEK.

Lasek (laser epithelial keratectomy sub) Action

The first stage of the lasek is, the epitel layer that is the most shallow of the cornea are removed. After that the surface of the cornea will get laser.

Correction made to change the surface of the cornea. After irradiation is complete, put contact lenses (soft contact lens) on the cornea as a protector. After approximately 4 hours if the layer is cured epitel the contact lens can be removed. Healing process is complete. LASEK appropriate action orang2 with a thin cornea or other irregularities cornea.

After Surgery

Control and critical care after surgery to prevent pain in the eye that arises in the process of healing, infection and complications. Remember that after get a laser your eyes must rest for a while (so you can not steer the car and swim). Usually with the help of eyedrops or take the medicine paracetamol is sufficient to overcome the pain after the operation.

Ranesi (doctor) Suggestions

Please really consider first, if you want to correct your eye which is valuable using laser surgery. If you already intend unanimously, talk first with your acquaintance who has a laser eye on their experience.

Request information to consumers about the organization of doctors and clinics that have a reputation of good. And do not forget to find out whether the clinic has a certificate that is recognized (ISO). You must remember that all the eye clinic is always a promise to provide high-flown, and they very rarely fail to include measures that clearly in their brochure!

If possible, always just one eye for the first that get laser and if the eye has healed well you can continue to the other. This is less practical and a little more expensive, but remember that you only have 2 eyes!

If your insurance company does not pay your treatment and you pay income tax in the Netherlands, then you can ask back a small part of the cost from the tax. First inform the tax office if you have hope to get back your money.

Of course I do not recommend you to not get laser eye surgery to cure your eye. The quality of almost every eye surgery undertaken by the experienced eye doctor in the good clinic is very good.

Laser Eye Surgery | LASIK (laser-Assisted in situ keratomileusis) Effek, You Must Know

Millions of people of North America do LASIK surgical procedures or laser-Assisted in situ keratomileusis (an aberration correction method for myopic, dioptric/farsightedness, and cylinder). Most satisfied with the results.

However, at this time Food and Drug Administration (FDA) want the warning to the hard material information to patients about the surgical complications occurred kemngkinan harmful.

What is LASIK Surgery

LASIK (Laser Assisted In-situ Keratomileusis) is an action with the refractive laser eye surgery made by ophthalmologic to improve myopia, hipermetropi, and permanently astigmatism. change the shape of cornea curvature, the cornea is the front of the eyeball and see-through. A laser device is used to make the incision flap (layer) on the eye cornea and leaving some still stick to the flap at the end of the cornea.

Before we continue the discussion on LASIK, it's good we discuss a bit about the anatomy, especially the part in this action LASIK.

Human eyeball has three layers:

• Fibrosa layer consisting of cornea and sclera
  Sclera consists of layers of fibrosa enwrap 5 / 6 to the back of the eyeball. Vision for the future through conjunctiva bulbaris ( "the white of the eye").
  Cornea is the transparent part of the mantle fibrosa enwrap 1 / 6 the front of the eyeball.
• Vascular layer consisting of koroid, silia body, and iris
  Koroid, a layer of dark reddish brown and sclera between the retina, forming the largest part of the layer vascular eyeball.
  Agency silia connect with koroid slices.
  Iris is the section near the front surface of the lens.
• In the layer (in the mantle), consists of the retina that have optics and the non-visual
  Optics the retina sensitive to visualize the light and has two layers: a layer neutral layer and pigment cells.
  The non-visual retina is the continuation of the cell layer and pigment layer of cells that pass the silia rear surface of the retina and iris.

Some procedures are performed in LASIK action:

Preoperative

The use of contact lens is usually stopped approximately 5-21 days before surgical action. Before the surgical action, the patient's cornea is reviewed using pakimeter to measure the thickness and with a topographer to measure surface contours. By using low-power Lasers, topographer create a topographic map of a cornea. This process is carried out to detect the astigmatism and other cornea deformity. By using this information, the surgeon calculates the amount and the location of cornea network which will be removed when operating. Usually, patients are given a prescription of antibiotics prior to this action to reduce the risk of infection after the procedure is executed.

Operative

Done when the patient is awake and moving. Sometimes a light sedative are given to patients, such as valium and anesthesia eye drops. LASIK three action steps:

a. Flap Creation

A corneal suction ring is applied to the eye, make eyes fixed on the place (that does not move). This step can sometimes cause bleeding (subconjunctival hemorrhage) in the sclera. This is a mild side effects that can be experienced for several weeks. Increasing the suction caused blurred vision for a while. This process is done with a mechanical microkeratomi use metal knives or femtosecond laser microkeratome (intraLASIK). A hinge left at the end of this flap. And behind the flap, show a stroma, the middle of the cornea. The process of adoption and this inversion can be less comfortable.

b. Laser Remodeling

The second step uses eximer laser (193 nm) to change the form of cornea stroma. Laser vapor the network without damage the stroma. To erase the network does not need to fire or cutting. Layer of network is taken about ten micrometer of its thickness. The use of laser ablation on the cornea stroma further acceleration in the improvement of the visualization and generate more light than the pain that earlier technique, photorefractive keratectomy (PRK).

View of the patient will be very clear when the flap is not lifted. Patients are able to see only white light encircle orange laser light.

c. Reposition of Flap

After laser re-shaping the stroma layer, flap position restored carefully by surgeon and checked the air bubbles, debris with the appropriate action on the eyes.

Postoperative

Patients are usually given antibiotic eye drops and anti-inflammation for several weeks after the surgical action. Patients are also more sleep and wear sunglasses to protect eyes from light, so that does not prevent the rub eyes when not sleeping, and reduce eye dryness. Patients must follow the doctors advice to reduce the risk of surgical complications after surgery.

The results of the very interesting, who does not like my vision is better without the contact lens and eye-glass. However much any posts about the benefits of LASIK surgery will be more prudent for prospective patients to realize the potential risk.

What are the complications of this surgery?

Subconjunctival hemorrhage is a common complication of minor post-LASIK. While the most common complications of surgical action is refractive dry eye incidence.

The risk of disruption to patients experiencing side effects visualization, such as halo, double visualization (ghosting), loss of contrast sensitivity (foggy vision) and glare after LASIK depends on the degree of ametropia before the surgery and other risk factors. Therefore, it is important to calculate the potential risk of a patient and not only estimates the average likelihood for all patients.

The likelihood of infection will also occur, at any time, anywhere in the incision is made in the body. This may require intensive treatment and may lead to temporary loss of vision or even permanent blindness.

And it is important to remember that the laser machine tools may not always do what they should do.

Some patients suffer side effects that damage the quality of vision even though they have improved the vision sharpness. For example, although the vision with the eye test chart (a test to measure the sharpness of vision) shows good results, some patients still can not see in light conditions with low contrast, such as when driving at night or in foggy conditions.

In one study, 41 percent of patients have good vision in the daytime, but some have lost their vision at night.

In another study, people who have short-distance vision (short-sighted) who undergo laser surgery, 80 percent can not see the traffic sign on the distance of 15 cars, and 40 percent can not see the traffic sign on the distance of 4 cars .

This is worrying, as well as that of a drunk driver. But with millions of people who undergo LASIK surgery, it should be asked how much the trip will be done at night.

Moreover, laser surgery can not stop the increase of age, and size for our age, the vision in the night, of course, have been decreasing. This causes a double-whammy.

Some patients have been suffering from post-operation problems of quality of vision such as double vision, or about the existence of such a circle of light on their blind vision.

May also occur under the action of professional treatment or excessive in the patient, resulting in less than 20/20 vision.

In one study, 36 percent of those who perform surgery on both eyes still need glasses. The report states that the other 2 percent from 10 percent of people still require glasses after LASIK surgery.

The other suffered from dry eye syndrome. In this case, the eye is not able to produce enough tears to keep eyes stay moist. This does not only cause restlessness, but sometimes also the haze, and this may become permanent, given the eye problem will continue to need regular eye drops.

And what all this means? This field does not currently intend to frighten people who want to perform LASIK surgery. This is more a form of expression is quite wise for patients to follow the advice of the Roman era which has been proved the effectiveness in a long time (time-tested), which is "please examine before buying a" let the buyer beware.

Only, you must be a patient who fully understand the information before agreeing LASIK surgery. And someone who says to you that there will be no complications, is a liar or stupid people.

Decisions even more difficult when LASIK surgery is done only for convenience not because it needs, given that the majority of cases end with good results.

The problem is, you do not know when rare complications will be occurred. It is a grisly sight when the loss occurred only because you want to remove my glasses.

Therefore a short description about LASIK. View from the benefits and complications incurred while this action LASIK surgery more profitable than conventional surgical measures. However, because the action LASIK is still quite new, possibilities the complication of this action more dangerous from the previous action.
