What is LASIK?
The laser correction eye surgery (LASIK) is a surgical procedure intended to improve your view and reduce your reliance on glasses or contact lenses. This means that you can enjoy a comfortable growing in your lives normal. Especially if you are active and those who enjoy sports or other activities, that LASIK gives you the opportunity to participate in your activities without being tied to Favorites wear glasses or contact lenses. Furthermore, the laser vision correction (LASIK) can eliminate the risk of long.

Can be used as laser eye correction surgery to deficiencies in the following:
- Myopia
- The length of
- Astigmatism
- Very soon, reading glasses

Maximum depends on the correct number of factors such as the thickness of the cornea and iris size and imaging of the eye, and there should not be any barriers within the eye such as glaucoma or white.

Age is possible to perform the operation? -
Can be conducted laser eye correction surgery at any age, but according to the circumstances of each case, meaning that they can perform this operation for children when there is a big difference in the size of the glasses between the eyes, in this case can be made the process of the eye vulnerable if the child is unable to afford eyeglasses so as not to weaken the eye. And possible in the situation of older persons, provided the absence of other eye diseases as mentioned above. The Age appropriate they are generally 18 years old, and the reason for this is to increase the proportion of stable size glasses at this age, so we do not have to re-LASIK again.

-What are the steps involved in the operations room and the time it takes?
Laser eye correction surgery does not take more than ten minutes, and the process under the influence of topical drops (psychedelic drug), and the patient feels any pain during the operation, and then I feel a sense of burning light for 2-6 hours.
All that is required from the patient, not a movement not to touch the eye and respond to some of the instructions given by his doctor during the operation.
After transferring the patient to the waiting room to see the doctor again and return the patient to the house.

-What then are the instructions after the procedure?
Vision after laser eye correction surgery a direct and clear and the patient feels as if it were seen through the fog will this feeling for a few hours. You are advised not to drive immediately after the operation. Can be seen in the patient's TV or read what I liked on the day of surgery that can help it. In the meantime, can scan the forehead and cheeks with a damp cloth taking care not to touch the eye. Is strictly prohibited forgot the eye for 48 hours. And patients can deal with whatever he wants after the operation. Doctor examines the patient during the first 24 hours after the operation.

What are the complications that may occur after the operation?-
After the dramatic advances in technology, the complications of LASIK are extremely rare, for example:
Correction of over-or at least required, can be treated with the increase or decrease the reuse. Continuing blurred vision after the operation, very rarely continue this complaint more than two weeks.

Will I get the strength of eyesight 6 / 6 after the operation? -
LASIK is an alternative to glasses, if the strength of vision glasses before six it can be on the process to give you the strength of eyesight 6 / 6, but some eyes suffering from a condition called lazy in the sense that the eye can not 6 / 6 glasses medical seizures despite the absence of any disease, and in this case will give the operation the patient's eyesight, which was given by her glasses before the operation.

Eye Anatomy

Anatomy of the human eye includes cornea, conjunctiva, (iris, choroid &), lens, blood supply, retina, vitreous & optic-nerve. For ophthalmologists, optometrists, medical, dental, and optometry students, eye-anatomy forms the basis for eye-pathology in diseases: dry eye, retinal detachment, macular degeneration, diabetic retinopathy.

Consists of the eye (eye ball) of the three layers are from abroad:
Solid: -
The outer layer of the eye, consisting of connective tissue strong and non-transparent to protect the eye - hard, but do not absorb light, reflecting white - most of the damage to the hatred of a solid eye only the front part of which is the transparent cornea.

- Choroid:
Layer that lies between the solid eye and retina - and anatomy of the human eye, we find that human chorionic contain a rich network of blood vessels, and the basic function is to support the retina and provide food and oxygen for them. Placenta covering two thirds of the eye ball only the part of the back.

-Retina:
Inner layer of the eye, and cover two-thirds of the hatred of the eye from the back of the inside - and anatomy of the human eye, we find that the retina is the layer that contains the receptor optical receiving and responsible for vision - where he is receiving light from itself and converted to electrical signals transmitted through the fiber neurological, visual and accumulated in the optical disk optical disk, or also called the spot blind (where the optical disk does not contain photoreceptors) to form the optic nerve - The network includes the flick which is a spot concave in the retina contain large amounts of receptors light and the use of eye Looks sharp - that the eye is a ring of light on this spot.

Components of the eye and parts thereof:
- Vitreous body:
Glass-filled eye ball - means transparent gelatinous - relates to forward is to muscle in the form of the lens so that if decreased less curvature of the lens, and if it is represented by the Deputy of the curvature of the lens, and focus the process of light on the retina of the eyes after relying on the body of the eye.

-Iris:
Before the lens of the eye are the iris - which gives the eye color - and anatomy of the human eye, we find that the human iris is made up of circular muscles and radial muscles - in the center hole called the pupil (iris) - circular muscles narrows the pupil and the pupil radial expansion eye by the amount of light - in the dark pupil expands to allow for a larger amount of light entering the eye to facilitate the vision .

- Cornea:
After the iris and in front of the eye are the cornea - the transparent and does not contain blood vessels, where they take what they need oxygen directly from air and food through the nomination of mixing water, a solution that fills the front room and back room.

- Front front - and the back room:
The front room is a space located between the cornea and iris - and the back room is the space located between the lens and iris - fills the aqueous humor of these two chambers which is located in the angle between the cornea and iris in the front room - the aqueous humor is responsible for eye pressure, if the pool and could not go out for some reason can lead to hypertension and eye disease known as blue water

Muscles that move the eye are: -
1 - straight brutal muscle (lateral) Lateral Rectus Muscle of the eye damage is outside any consideration to the external (by eye).
2 - straight muscle humanism (internal) Medial Rectus Muscle damage the eye to look towards the inside of the nose.
3 - straight muscle upper Superior Rectus Muscle damage the eye to look up and inside.
4 - straight lower muscle Inferior Rectus Muscle damage the eye to look down and inside.
5, - muscle, oblique upper Superior Oblique Muscle damage an eye to look down and out.
6 - lower muscle oblique Inferior Oblique Muscle damage the eye to look up and out.

We know from anatomy of the human eye, which consists of the human eye

Contact lenses: A lens with a thin hemispherical shape made of transparent plastic material mixed with water to varying degrees angle is designed to latch onto the cornea. And purpose as the purpose of the lenses glasses in the function of improving the visibility (consideration) in the eye to correct refractive errors as minors and far-sightedness and astigmatism (astigmatism) and after consideration of the reading .

Should be available in the specifications to avoid problems with contact lenses following ideal:
1) Very light weight and small size to fit with the size of the cornea.
2) easy handling, and vision can be distinguished easily.
3) a high degree of purity and transparency.
4) to be very thin and polished edges minutes.
5) Do not bend willingly on their own.
6) flexible and non-stretchable.
7) is not affected by changes in weather conditions such as temperature, humidity and atmospheric pressure.
8) can be used for a long time.
9) Do not change color with use.
10) to be of the eye to be borne comfortably enough.
11) to be of a high water content.
12) allows the passage of tears to the cornea easily to feed the cornea and with a high oxygen permeability.
13) can be cleaned and sterilized easily.
14) free movement on the surface of the cornea.
15) can correct all refractive errors, eye (of defects).

It is necessary to follow the instructions of a specialist eye to be used correctly so as not to lead to problems with contact lenses and serious injuries in the eye.

Some of the problems with contact lenses, corneal ulceration, occur in users of contact lenses for long periods of time than prescribed for each type of lenses, for example, who use contact lenses during sleep daily, and follow the appropriate instructions.
Appreciates the possibility of hantavirus infection of the cornea in ulcerative users of contact lenses for smokers more than about 3-8 times, including in non-smokers.

Exposure to ultraviolet radiation a risk factor Allied with the blue waters; there are some types of contact lenses protective.

Note:
If you feel uncomfortable in vision after the introduction of the lens for an eye, make sure of the following:
1 - If the lens is in place, unplug them and make sure that no residue of fat or beauty products.
2 - It may be placed in the eye lens is not appropriate (left instead of right or vice versa).
3 - may be the lens upside down, which makes them uncomfortable.

4-contact Lenses may slip from its place or may enter a foreign object such as dust or dirt in the eye and cause pain and redder and abundant tears which requires removed and washed and worn again.

5-Wearing contact lenses for a longer period may cause the appearance of some signs and symptoms such as: pain, eye redness, itching increased secretion of tears, sensitivity to light.

- You can remove them immediately if you experience problems with contact lenses the following:

• itching or burning or tingling in the eye.
• feeling of a foreign body in the eye.
• The presence of abnormal secretions in the eye.
• flushes excess eye.
• blurred vision or the appearance of rainbows or halos around objects.
• Dry eye may occur in case of wearing contact lenses on a continuous basis or for a period longer than necessary.
It could be any of the symptoms listed an indication of the serious condition such as infection or ulceration of the cornea, so it is necessary to follow the treatment and to avoid any serious damage to the eye.

- Some medications, such as on drugs, refrigeration and sensitivity to congestion, diuretics and of muscle relaxants, tranquilizers and treatments for diseases and dizziness associated with travel, may cause dryness of the eye or a growing sense of the presence of the lens.
You should not use eye drops during the use of contact lenses, if necessary, one can use the drops before using the lens not less than half an hour.
